ALM Busy Circuits

Notes: Gritty drum voice module based on new old stock Yamaha FM synthesis chips, also capable of a decent range of synth tones. User-friendly knobby interface with a decent range of CV inputs for modulation.

Supplier's notes:
'Akemie's Taiko' is an authentic complete FM synthesis based drum voice created using original Yamaha IC's. It builds on the same technology used in the mighty Akemie's Castle but in a more complete triggered voice form featuring both signal generation and envelope shaping.

The module provides CV and direct control over a number of FM parameters including algorithm selection, operator release envelopes, ratios, waveforms & feedback. This gives a massive range of unique sounds.

The voice is able to track 1 volt per octave allowing it to be used for melodic lines as well as percussion. Also optional 'frequency ramps' can be enabled for additional audio effects.

The drum voice includes a trigger input as well as accent and choke trigger inputs to add further expressive and rhythmic control.

Notes: The Jumble Henge is a 16 input stereo spectral mixer with a unique patch-based mixing interface in a compact space. Each input has a carefully tuned resonant analog filter and a unique fixed pan value, providing each sound its own space within the mix. There is a Mix control to adjust the depth of the filtering and a clean external stereo input for chaining with another mixer or extra sound source. Jumble Henge is a space efficient solution for creating rich stereo mixes from a number of both mono and stereo sources.

INPUTS
Vertical and horizontal patch position determines a source's spectral and stereo placement in the mix respectively.

Aside from centred inputs, every input sits in its own unique pan position, helping to keep a separation between sounds but building a complete stereo image when combined.

The centre right inputs of the top two rows are normalised to the centre left inputs. - i.e if just a left input is patched it will be effectively panned center.

Towards the highs the panning becomes wider - as the human ear better pinpoints direction at higher frequencies, whereas the lows remain more centred for a tighter, more focused sound.

MIX CONTROL
Mix control for the overall depth of the filters applied to the inputs. Note: a slight volume increase occurs near the centre of the dial.

EXTERNAL INPUT
An additional clean stereo input pair for chaining with another mixer or additional source. Right input normalised to left input to accomodate mono sources.

OUTPUTS
Stereo mix output, the sum of all 16 inputs.

Jumble Henge was designed in collaboration with Worng Electronics and is based on the 'SoundStage'.

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.

FREQ INPUTS AND ATTENUATORS
Control voltage inputs here are combined with knob offsets to set the final cut off. Attenuversion control allows for both attenuation and inversion of the CV. Expects approx. -5V - 5V input.

RES INPUTS AND ATTENUATORS
Attenuated control voltage inputs here are combined with knob offsets to set the final resonance.
Expects approx. -5V - 5V input.

AUDIO INPUT 'In'
Signal inputs to the filter cores for processing.
Input sources may need to be attenuated, filter will drive from hotter input levels.
The Left input is normalised to the right (unless 'Feed' is enabled).

Notes: The MCO MK II is a highly versatile digital VCO and voice module inspired by 90s/00s digital synths shrunk into just 6HP.

It offers a broad collection of unique, high-quality synth voices, each with extensive, customizable parameters. These parameters can be directly controlled or modulated through assignable internal and external sources. Certain per-voice parameters support audio-rate modulation, including FM, sync, and DSP. Each voice also supports up to four-voice chords, external-triggered envelopes, multiple LFOs, and dual audio outputs for comprehensive desktop like synth functionality.

Voices include a multi dimensional wavetable oscillator based on the original MCO, a complex additive synthesis engine, a multi mode 'JP' type digi-synth, a lush virtual analog implementation, a fully featured vocoder, a bass synth for both kicks and sub sonic tones and finally arebirth and porting of our discontinued SID GUTs chip voice.

Each voice includes factory presets as well as the ability to store and recall user presets. All state is preserved across power cycles.

The MCO is designed to be familiar, quick and easy to use with a high resolution colour display and a rich visual user interface.

A USB-C connection allows for easy firmware updates, user wavetables upload and device config backup and restore. Axon expander modules are also supported to increase CV control options.

Notes: The 'MEGA-TANG' is a 4-channel linear VCA and stereo mixer providing per input control over level, effect send, pan and muting. Designed for live use in mind with a simple & compact layout, the 'MEGA-TANG' builds on the clean and transparent sounding Tangle Quartet VCA by adding a stereo mix output, effect sends (mono send with a stereo return) which pair great with the MFX, manual panning, soft mute buttons with LED indicators and an expansion port for future expandability.

Individual VCA outputs are available which remove the channel from the main mix (useful for cueing and monitoring). All signals are Euro level and bar the effects return, DC coupled for CV use as well as audio.
