Notes: A clever hybrid of quad VCA, function generator and more in this chunky module. Four channels of oscillators, envelope generators and VCAs, plus slew, voltage sources and plenty of CV control.

Supplier's Notes:
Four channels of function generator, oscillator, slew limiter, envelope, and VCAs. This module brings the ultimate in flexibility as it can be used as a standalone synth voice, a massive amount of modulation, or a four channel envelope generator w/ mixer. We believe this makes QARV a great first module and a great addition to the largest of systems.

All four channels have the following features:

Uni-polar oscillator mode
Attack and release time control via potentiometer and via input jack
Shape control that controls shape for both attack and release
Output attenuverter
VCAs that normal to each subsequent channel (CH1 -> CH2, etc.). So you can get a mix of all four channels out of the CH4 VCA output (unless you patch a VCA output from an earlier channel)
Channels 1 & 4

Voltage source (CH1 - 5V & CH4 - 10V)
CH1 & CH4 can be switched between IN (slew mode) and TRIG (envelope) mode
RISE and FALL gates. You can use our G&T module to turn these gates into triggers.
Channels 2 & 3:

Bi-polar oscillator mode
Dedicated IN and TRIG jacks (helpful for adding offset to a triggered ENV)
BOTH input jack to simplify patching both the attack and release (also inverts the input to give more standard pitch tracking of higher voltage equals higher pitch)

Notes: A 22hp version of Mutable Instruments Elements. It is functionally equivalent and therefore runs all firmware options and having identical sound characteristics. This version is great compromise between the tight spacing of Atom and full size original, which is a bit large.

Width: 22hp
12V: 130mA
-12V: 10mA

Module power connector can be connected either way on the module side.

Notes: After Later's redesigned take on the classic Mutable Instruments Rings module offers all the distinctive resonant synth sounds you'd expect, from strings to percussion. Great value.

Supplier notes:
This is an exact hardware replica of the Mutable Instruments Rings module.

Notes: This is where Storm and Monsoon meet to create the latest improvements on the original Clouds design. With Typhoon you get all of the features of Storm combined with sliders and layout of Monsoon in 16hp. Typhoon runs the SuperParasites firmware, so no more having to swap between Parasites and Kammerl firmware options. Some of the notable features are:

Dedicated blend controls for Feedback, Panning, Mix, and Reverb (similar to Monsoon)

All eight modes from Parasites and Kammerl

Stereo VCAs

input/output mutes

Exponential and linear pitch controls

Universal CV routing and random CV signals

Comes with an exclusive black and gold panel, power cable and one year warranty.

Notes: uBurst

This is a new build of the micro version of Mutable Instruments Clouds. The module retains all the functions of the original Clouds, taking up significantly less rack space.

These modules use tall bushing potentiometers to offer a more stable feel.

The module is fully assembled, tested, and calibrated. Eurorack power cable is included.

Notes: An 8hp version of the retired Mutable Instruments Grids. It is an identical functional clone, so it will behave in the same was as the full size version, and will run any firmware that runs on the full size version.

Notes: Ornament & Crime for 1U Intellijel format

This is functionally identical to the 3U version, just re-oriented to fit in 1U racks. Ornament & Crime is designed by mxmxmx.

The apps currently available in Ornament & Crime:

CopierMaschine is an enhanced version of the original quantising digital emulation of a four stage analogue shift register (ASR).

Harrington 1200 provides basic neo-Riemannian Tonnetz transformations of triadic chords, triggered by the digital (gate/trigger) inputs.

Automatonnetz combines Tonnetz transforms with a "vector" sequencer - it can be both a chord sequencer and a melody sequencer, but not of the usual kind.

Quantermain is a quad pitch quantiser for external voltages, with editable scales; it can do clocked (trigger-driven) quantising, or continuous quantising, with a latency of under 100 microseconds; it also features quad Turing Machines, May-Verhulst logistic maps or byte beats as optional, semi-random, internally generated CV sources.

Meta-Q is a dual-channel quantiser, similar to Quantermain, but also offering scale and note mask sequencing.

Quadraturia is a wavetable quadrature LFO, based on the "Easter egg" in the Mutable Instruments Frames module.

Low-rents is a dual Lorenz and Rossler (strange attractor) modulation generator, partially based on the "Easter egg" in the Mutable Instruments Streams module.

Piqued is a quad voltage-controlled envelope generator, based on envelope generator code from the Mutable Instruments Peaks module, but extending it with voltage control, additional envelope types, including re-triggering (looping) envelopes, additional segment shapes, adjustable trigger delays, and a unique Euclidean "trigger filter" which turns the app into a Euclidean rhythm generator which can output envelopes, not just gate or trigger pulses.

Sequins is a dual-channel step sequencer offering 4 "tracks" of up to 16 steps each; tracks can themselves be sequenced.

Dialectic Ping Pong is a quad bouncing ball envelope generator, based on a hidden mode of the Mutable Instruments Peaks module.

Viznutcracker, sweet! is a quad "byte beat" equation generator, which can be used as an audio source to generate curious but often interesting 8-bit noises and tunes, or which can be clocked by an external source to produce "byte beat" control voltage sequences. "Byte beats" were first described in 2011 by viznut (aka Ville-Matias Heikkila).

Acid Curds is both a chord quantiser (sometimes called a "harmonic quantiser" for external pitch voltages), and a chord progression sequencer.

References is an utility app that outputs specific reference voltages on each channel to help tune or calibrate VCOs and other modules. It also includes a high-precision frequency meter and note tuner, a high-precision BPM (beats per minute) tempo meter, and a closed-loop calibration mode.

Notes: The Gemini 2412 is a creamy, extremely fat sounding dual filter based on vintage Oberheim SEM circuits. In addition to high-pass, band-pass and low-pass, there is the infamous variable filter type, which allows you to blend between several characteristics. Thanks to its dual concept, serial and parallel modes of operation and an ingenious modulation system, the Gemini 2412 should not only be able to achieve classic, extremely bulbous results, but also wafting stereo effects and lively formant sounds.

Notes: The Low Fat is a new 2hp Eurorack module by AJH Synth, it's a High Pass filter, with frequency control by either manual pot, and/or external CV with attenuator. It's intended to compliment other filters, particularly low pass VCF modules, in practical tasks such as removing excessive low frequencies, for example when the bass is swamping a mix. It can be switched between 6dB (1 pole) response and 12dB (2 pole) response.

By patching a CV signal to the FCV input it can be voltage-controlled and used musically as with any other VCF. When used in conjunction with a LP filter it forms a fully customisable band pass filter, allowing the range of passbands to be cherry-picked. Feeding in a 1V/Oct pitch CV and setting the FCV pot to a suitable level allows it to track an incoming pitch CV, so the amount of High Pass filtering remains constant as the pitch of the incoming VCOs traverse up and down the frequency range. This can be particularly useful in creating percussive sounds, such as snares and hats, but also on sequenced bass lines. Since it is only 2HP it's a great way to occupy one of those frustrating gaps in your eurorack modular case with something that is deceptively useful, and adds another dimension to the classic bass monster that is the Transistor Ladder Filter.

Notes: Truly unique one from AJH, based on the sound of NASA's Apollo voice transmissions. Think outside the box and process drums and synths through this thing. Freaky. May or may not allow you to communicate with real astronauts.

Supplier's notes:
Here's a bit of fun for all fans of space missions from the previous century! This module is designed to re-create the ground to space and space to ground transissions from the Apollo era.

To be "Mission Control Houston" the Quindar PTT (push to talk) button adds a short 2,525Hz Qindar tone to the start of the transission, then at the end of the message the PTT button or switch is released and a short 2,475Hz Quindar tone is added to the audio. The bandwidth is slightly reduced in this mode.

For "Astronaut comms" we press the Capsule PTT switch, which allows us to add coloured noise, distortion, bandwidth reduction and either hum or LGM (Little green men space tone) noise to the audio signal. A deep space electret condenser mic is supplied and an be used with the MIC input.

Obviously the Lunar Module can also be used to add noise, hum, distortion, bandwidth reduction and LGM noise tone to any modular level audio too, and if the mic is left attached theremin like sounds can be added too with careful loudspeaker feedback.

Notes: This useful module is a Bipolar Mixer, DC voltage source and Linear DC coupled VCA.

- With no input to channel 1 the Input 1 pot becomes a voltage source with a range of +/- 6V.
- The control pot and input for channel 4 can be switched to become an offset control and/or a second CV input for the VCA.
- Input 3 has 2x gain, so it can amplify lower level CV's too.
- All inputs are bipolar, which means that either non-inverted or inverted version of the input signal can be added to the mix depending upon the Input control being turned clockwise (non-inverting) or anti-clockwise (inverted). The 12'o'clock position is zero.

Notes: Two independent Contour Envelope Generators in a single 12hp wide Eurorack module. These are very accurate replicas of the Model D contour generators, with identical circuitry and component values running on the correct +9.3V and -10v supply voltages of the original; so they exactly replicate the original envelope response along with all of it eccentricities. Extra features include manual trigger buttons and envelope status LED's.

The contour generators played a larger part in the sound of the Model D than many people realise. There are two factors that make them unique, firstly the exponential slope when is used in conjunction with the (near) linear slope of the original VCA which is responsible for the famous Model D "punch". Secondly, the re-trigger behaviour is quite unique, multiple retriggering increases the output level so that either the volume increases incrementally, or the filter opens incrementally with each extra key press.

AJH Synth have added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesiser, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).

Notes: Five-channel mixer with mutes, built-in VCA, switchable overdrive and LED level meter. Simple, straightforward, high-quality stuff from AJH.

Supplier's Notes:
The MiniMod Muting Mixer & VCA is a 10HP wide, five channel audio mixer with many useful features. It is available with either a black (Dark Edition), or a silver front panel.

The mixer section has five input channels, and each channel includes a bi-colour tactile LED switch that can instantly mute or un-mute the channel, replicating the oscillator on/off switches on the original Model D synthesiser. This arrangement is more convenient than regular switches as each illuminated switch shows the on/off status of the associated channel and multiple buttons can be pressed at once, making it very useful for live performance.

AJH have also included a four segment LED level meter so that the overall level can be seen at a glance and adjusted to prevent the output from getting too "hot" and causing distortion in other modules further downstream.

It also features a VCA that is integrated into the output section, and this can be switched from linear to exponential response - this allows it to be used as a voltage controlled sub mixer or as a stand alone VCA with five inputs.

Lastly, AJH added a wonderfully soft and warm sounding overdrive circuit that can be switched in to add smooth, tube like distortion. This works in a similar fashion to a master volume guitar amplifier, so the amount of overdrive can be varied widely with different settings of channel and master output levels.

Notes: The Tone Science Chance Delay is a unique concept in Eurorack modules as it combines chance and randomness, with pulse delay and pulse conditioning. It is a collaboration between electronic musician/composer Ian Boddy and AJH Synth.

It can perform as a Chance generator, but is also capable of pulse stretching for Trigger to Gate conversion, pulse shortening for Gate to Trigger conversion, Gate Delay, Sub Bass Generation and also "divide by n" clock division.

There is a wide range of control and all functions can be operated manually from the front panel or can be automated using external CV voltages. Chance can range between 0 to 100%. The Gate out can be delayed by anywhere between from 0.5mS to 30 Seconds, and the output Pulse length can also vary from 0.5mS to 30 Seconds.

The TRIG push button allows manual triggering of pulses, also determined by the Chance control, and a green LED shows the output pulse status.

Includes a handy "Gate pass through" mode; when the Length control is set to zero the incoming pulse or trigger will still be determined by the Chance and Delay controls, whilst the outgoing gate length will be the same as the incoming gate length.

Compact 8hp form factor and very low power consumption make this an excellent addition to any Eurorack system.

Key features:

Chance, Gate Delay time and Pulse Length can all be set manually or controlled using external CV voltages.

The 'TRIG' push button allows manual triggering, and Chance will be applied to any manual triggering too.

Fast processing allows operation into the lower audio range, so it can perform sub bass generation on drone type sounds. In this mode the Length pot (or an external Length CV) can be used to change the PWM of the output waveform.

After the initial trigger pulse has been acted on, further incoming pulses are ignored until the current cycle has finished. This useful feature allows it to perform "divide by n" division on gate pulses, so it can be used for clock division, and the delay function can be used to add a "swing" away from the rhythm.

Gate pass through mode - if the Length pot is set to zero, then the incoming gate length is preserved, so in this case the gate has Chance and Delay time applied to it, but the outgoing gate length is the same as the incoming gate length.

By setting Chance to 100% and Delay to zero (0.5mS) it can be used as a Gate to Trigger converter, or a Trigger to Gate converter, depending on the Pulse length set with the LENGTH control. We can also use an external Length CV to shorten or increase the length of the output pulse in real time.

Fast and slow ranges for both DELAY time and PULSE length - Fast range is 0.5mS to 2 Sec and Slow Range is 2 Sec to 30 Sec.

Green status LED shows when the output pulse is high.

Front panel controls

Chance Control and CHA Input

This sets the probability of an incoming trigger or gate being passed through to the Pulse Generator circuit. The chance can be set anywhere between 0% and 100%.

The CHA input allows an external control voltage (CV) to control chance remotely. In this mode the Chance control acts as an attenuator for the incoming CV. With the Chance control fully clockwise a CV of +5V will give 100% chance, and lower CV voltages reduce the Chance accordingly. For example, a +2.5V CV will give a 50% chance. The attenuator function is useful if we are using higher control voltages of for example 0 to +10V. If we set the Chance control to the 12 o'clock position it would then halve the incoming CV signal, so in this case +10V will give 100% chance and +5V will give a 50% chance. Negative CV voltages are ignored and will be treated in the same way as zero volts..

Delay Control and DEL Input

This sets the delay amount that is applied to the leading edge of the incoming Gate or trigger received at the IN jack (or a press of the Manual Trigger button), assuming that the "Chance" has been determined to be positive. With the Delay Time switch set to FAST the Delay range will be from 0.5mS to 2 Seconds. With the Delay Time switch set to SLOW the Delay range will be between 2 Seconds and 30 Seconds.

The DEL input allows an external CV voltage to control Delay Time remotely. In this mode the Delay control acts as an attenuator for the incoming CV. With the Delay control fully clockwise a CV of +5V will give the maximum Delay time of either 2 Seconds or 30 seconds depending on the position of the Fast / Slow switch. Lower CV voltages reduce the Delay Time accordingly, so if we apply a CV of zero volts then we will get the minimum Delay time. The attenuator works on any CV patched to the DEL input in the same manner as described for the Chance control.

Length Control and LEN Input

This sets the length, or rather pulse width of the output pulse. With the LENGTH Switch set to FAST the pulse length can be anywhere between 0.5 mS to 2 Seconds. With the LENGTH Switch set to SLOW the pulse length can be between 2 seconds and 30 Seconds.

The LEN input allows an external CV to control Delay Time remotely. In this mode the Length control acts as an attenuator for the incoming CV in the same manner as the Chance and Delay controls.

Setting the Length control to zero invokes "Gate pass through" mode - in this case the incoming gate length is preserved, so the incoming pulse or trigger will still be affected by the Chance and Delay controls, but the outgoing gate length will be the same as the incoming gate length. Turning the Length control slightly clockwise will then invoke the minimum pulse length around control position 1, and further clockwise rotation will increase the Pulse Length as expected. This behaviour also applies to external CV's patched to the LEN input, where a CV of 0V will enable Gate pass through mode.

Fast / Slow mode switches

These switches allow the selection of Fast or Slow mode for Delay time and pulse length, so these ranges can be selected independently for Delay and Length. Fast range is 0.5 mS to 2 Seconds, and Slow range is 2 Seconds to 30 Seconds.

TRIG Switch

The TRIG push button allows manual triggering, and Chance will also be applied to any manual triggering, so depending on the setting of the Chance control, pressing the button has a chance of not doing anything! Holding the button down keeps the incoming gate high for as long as the button is pressed, however this is only really relevant in "Gate pass through" mode - normally only the leading edge of the input pulse is used.

IN - input jack

Connect your input here - a gate, output from an LFO, or even waveforms from a VCO. Any negative component of the input voltage will be ignored, so unipolar or bipolar signals can be used.

OUT - output jack

This outputs the binary pulse (or stream of pulses) that are generated by the Chance Delay circuitry. The gate low level is 0V and gate high level is +6V. The green status LED shows if a pulse is currently being generated.

Notes: The MCFx2 is ALM's state variable 'MCF' filter made double. It features 2 identical classic analog 3 pole state variable filter cores each with Low, High and Band Pass (or Notch) outputs. Direct and voltage control is provided for both filter cut offs and resonance. Switches allow the filters to function as one, with the 'Feed' switch internally routing audio from one filter to the other in series and the 'Link' switch linking the cut off controls for both filter cores. MCFx2 expands on the great sounding MCF filter to offer both serial and parallel functionality for stereo operation, dual peak, tighter slopes and other complex filtering set ups.

FREQUENCY CONTROLS
Sets the base frequency for the filter cut offs. The v/oct and frequency inputs are added to these.

RESONANCE CONTROL
Sets the level of resonant peaks atop the cut off frequencies. The resonance can get particularly aggressive going into self oscillation with the control past 12 o'clock.

OUTPUTS
Each filter output is 3 pole with an 18dB/oct slope.
Low - low pass filter outputs. Passes frequencies below the cut off.
High - high pass filter outputs. Passes frequencies above the cut off.
BP/Notch - band pass or notch filter outputs. Jumpers on the rear of the module select one or the other for each filter.
Passes frequencies within (BP) or outside (Notch) a narrow region around cut off frequency.

LINK BUTTON
Links the left cut off to parallel control both filters. The right controls will now set the max range of the right core. Both filters will track together when the right cut off is fully clockwise.

FEED BUTTON
Routes the output of the left filter core to the input of the right (unless patched), with the desired output filter type selected via jumper at the rear of the module.

Notes: 'MUM M8' is an 8hp Eurorack low pass filter building on the filter design used in the classic Akai S950 12 bit sampler with the addition of resonance, voltage control, clipped saturation and a dedicated VCA.

The low pass filter gives the recognisable super smooth vacuum like tone sucking sound which works magic on complex sources. The addition of clipped overdrive and intentionally aggressive self-oscillating resonance compliment the smooth filter core by juxtaposing it into more wasp like territory with acidic squeals and a more gritty sound.
Mum M8 features dual voltage control with attenuation (and inversion) of filter cut off and voltage control of resonance together with dual audio inputs - one of which includes a VCA to with the capability to aid overdriving signals into the filter core.

The filter core is a 6th Order Butterworth switched capacitor type design featuring an analog core but controlled by a high speed digital clock. This produces the characteristic smooth sounding filter but, as with the original S950, has a relatively high minimum cut off as to avoid 'clock bleed' into the filter output from the digital control. This minimum cut of point (and introduction of bleed if required) can be controlled via trimmers on the rear of the module (see calibration chapter). It is not unusual for there still to be some low-level artefacts from the clock present, particularly during filter sweeps - these add to the filters character.

The motivation for the module came from discussing filters in classic samplers with the artist Jack Adams - aka Mumdance. Jack suggested investigating the S950's filter well known as for it use in classic use in early jungle and hardcore. From that point onward Jack provided inspiration, help and feedback in the development of the filter. Big up Mumdance.

Notes: 'O/A/x2' is a dual channel attenuverter with each channel also including a bipolar voltage offset and LED monitoring. The module is primarily intended for fine grain flexible 'editing' of control signals (i.e changing the phase, level and DC offset of an LFO signal) but also has uses with audio signals such as attenuation, inversion and mixing.

Technical Specifications:

Supply: +/-12V (Reverse voltage protection)
Current Draw: ~50ma
Size: 4 HP
Depth: 32mm (including power header)

Notes: 'Pamela's PRO Workout' is a compact programmable clocked modulation source for your Eurorack modular system. It provides 8 highly editable outputs producing various control voltage signals correlated and synced to a BPM based master clock.

Each output can provide everything from simple clocked triggers, complex rhythmic waveforms, quantised melodic patterns to random chaos with direct and assignable CV control over numerous parameters. These features together with a quick and easy to use interface provide almost limitless synced modulation possibilities in a tiny space.

Building on the original 'Pamela's Workout' & 'Pamela's NEW Workout' the evolved 'PRO' Pam maintains the precursor's form factor and intuitive workflow but improves and adds many new features with upgraded hardware, more CV inputs, a new full colour hi res display and rewritten software adding many new enhancements like micro grid timings and cross output modulations.

Through optional expander modules more CV input and outputs can be added with support for external non euro equipment through Midi and Din Sync outputs. Please enjoy your next generation PRO workout!

Size: 8HP
Power: +12v 60ma / -12v 10ma
Depth: 32mm (approx with power header)
Outputs: 0-5v buffered low impedance. 12 bit res. 3.8khz max update freq.
Inputs: CV 0v-5v / Clock, Run - rising edge 700mV min.

Notes: Two control sections provide a sweepable cut or boost to a selectable upper and lower frequency band. The module has two ac-coupled audio inputs, one of which has an attenuation control for basic mixing, and a single audio output.

The 'PE-1' is inspired by the EQ circuits used in early 'Portastudio' type 4 track tape mixers. Warm up a digital source, fine control a live performance, extend a mixer, tweak a feedback loop - there are many uses for this great sounding EQ.

Features:
- Provides +/-12db of boost and cut across 2 selected frequency bands
- Dual input with single attenuation control
- Reverse polarity protection.
- Skiff friendly
- Designed and made in the UK

Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Notes: The 'Quaid Megaslope' is a five stage function generator or modulator which operates in one of 3 modes; a multistage 'CZ' or 'Juno' style complex envelope, a super flexible LFO and a step sequencer with per step programmable slew or slides.

Each mode produces a varying output voltage moving from point to point across a set number of chained together stages. Each stage features a destination level, an overall rate or time to reach its destination level and a variable slope for the output path to take. As well as direct control, every stage feature voltage control of both level and rate. There are both unipolar and bipolar voltage outputs together with triggers emitted for the end of each stage and the end of a full cycle.

The Quaid Megaslope is designed to be fun, flexible and intuitive to use.

Notes: The 'S.B.G' is a compact utility module intended for the interfacing of guitar effect pedals with your eurorack modular system.

It provides both attenuation and amplification of audio signals for level matching together with a crossfade control to conveniently adjust the wet/dry mix of a processed signal. The module also offers regulation of outgoing CV signals for safer use of pedal expression inputs.

Technical Specifications:

Supply: +/-12V (Reverse voltage protection)
Current Draw: ~30ma
Size: 4 HP
Depth: 22mm (including power header)

Notes: THE SBG-PRO supports mono, stereo, balanced, and unbalanced input and output via 6.35mm jacks with level matching controls with clipping indication. The module features both direct and voltagecontrolled equal power crossfading between wet and dry sources.

Additionally, an expression input, along with the included 'floating ring' cable and conditioned output, ensures safe, voltage-limited CV control of external devices from your modular system.

The module extends its sibling, the original S.B.G, by adding full size stereo balanced jack connections and voltage control focusing more on connectivity with not just pedals but also pro audio equipment including rack effects, 500 Series modules and mixing consoles.

Notes: Eight channels of audio and CV sampling with real-time editing and processing. Does basic sampling well but quickly gets creative and weird.

Supplier's notes:
The 'Squid Salmpler' is a Eurorack 8 channel audio & CV sampler. It is designed for immediate real time sampling, editing and mangling within a modular context.

Taking influence from early hardware samplers, The Squid Salmple focuses on usability and instinctive operation, incorporating a proven Pamela's Workout style user interface for minimal screen dependence and a fun, hands on experience.

With support for sampling and playback for both audio and CV, as well as CV control of all parameters, on-the-fly bank loading and saving to USB, The Squid Salmple brings a unique take on old school sampling into the modular realm.

The Squid Salmple comes with a USB Stick containing approximately 90 banks of original carefully curated royalty free samples. This includes a wide range of sounds from classic drum machines and weird synths to field recordings and CV modulations. Banks are provided by both ALM and some of our favourite artists and friends including Mumdance, Solid Blake, Russell Haswell, Lauren Flax, Dave Burraston (NYZ), Sue Zuki, Dungeon Acid, Sasha Lewis and Andrew Duff.

Notes: The 'Stereo Sum' is a unity gain summing mixer that features four stereo input pairs summed as pairs to two independent mix outs or all as a single combined mix. It is a useful utility for efficiently combining outputs of multiple stereo sources, such as the MEGA-TANG and Jumble Henge mixers or multiple MFX returns. The inputs accept stereo or mono signals (via normalisation) which can be audio or CV (module is DC coupled) and the top mixer's outputs are normalised to the bottom mixer section meaning if the upper output is left unpatched the two upper inputs will be added to the lower output.

Notes: The successor to Dinky's Taiko, Tyso Daiko is a 12-bit dual digital drum voice, with built-in analogue tilt EQ and wavefolder, plus extensive CV control. Intuitive, powerful and versatile.

Supplier's Notes:
The 'Tyso Daiko' is a dual 12-bit digital wavetable drum voice with full voltage control and an analogue EQ output path.

The twin voices are independently triggered and output, but share pitch, envelope and other parameters of a swept wavetable oscillator. One voice is output through a voltage controlled analogue tilt EQ emphasising upper or lower frequencies.

The other voice is output through a digital wavefolder which adds increasing timbral complexity (to noise).

Both voices respond independently to an accent input and the first voice is able to be 'choked' . A surface control allows for fine control of additional transients from a click to a slow attack. Full voltage control including a V/Oct pitch input makes the Daiko an expressive and wide ranging drum module with extremely wide pallet of sounds with lots of modulation possibilities.

The Daiko succeeds the original Dinky with the same spirit but much improved control, new features and new wavetables.

Notes: Expandoor

The Expandoor gets you quickly and simply using AMP's Melody Oracle, Star Song, or Touch Tones (as well as other possible future devices) as a CV and Gate controller. It outputs Eurorack-compatible CV and GATE signals, transforming your AMP device into a versatile and novel modular synth sequencer or controller. The Expandoor can be used as a standalone tabletop box, or mounted in a 3U 10HP rack space.

Three independent GATE outputs:

Just as the three "Register" zones on your AMP device gate the audio for the three octaves of the built-in synthesizer, there are three corresponding gate outputs on the Expandoor. The 1/8" jacks labelled "BS" "LH" and "RH" output ~11V DC gate signals whenever those zones are gating "ON" on your AMP device.

CV output, tuners and LED indicators:

The jack labelled "CV" outputs a tuned set of CV values (0-11V), tuned independently but correspondingly, to the set of tuners on your AMP device. The row of multi-turn tuners on the front panel allow fine tuning of each CV state. One tuner is active at a time, depending on the state of the "INTERVAL" zones on your AMP device. The active tuner is conveniently indicated in real time via lights found to the right of the tuners. The indicator lights serve a second function of showing you which tuner on the controlling AMP device is also active in parallel.

AMP LINK jacks

The AMP LINK jack on the bottom left of the front panel (with the arrow pointing IN) connects your controlling AMP device into the EXPANDOOR. Use only shielded CAT 5 or CAT 6 cables and connectors (the correct cables will have metal end connectors). The AMP LINK jack on the right outputs a signal identical to the input, allowing chaining of multiple Expandoors and/or Wave Expanders. Do not plug more than one AMP controlling device into a single Expandoor simultaneously, or damage to the devices could occur.

Each controlling device requires its own Expandoor or Wave Exapnder, but multiple expansion modules can be chained from one controlling device. One potential benefit to chaining expansion modules is the ability to output multiple tuned, corresponding but independent, CV channels. Meaning multiple sets of harmonic values could be tuned and accessed at the command of the single controlling AMP device, or accessed via other modules in your system.

Tech specs:

Input: AMP LINK via shielded CAT5 or CAT6 cable
Power: 12V DC Supplied via AMP LINK
Outputs: 3 Gate (~11V unipolar), 1 CV (variable 0-11V unipolar)
Tuners: 8 multi-turn fine tuners for CV, with indicator lights
