Notes: Erica Pico VC EG is versatile looping AD/ASR envelope generator with voltage control over attack and decay times. It has automatic Trigger/Gate detection, as well as "drone mode" - at full CW setting of the Decay knob, the envelope is full open. In the LOOP mode you can retrigger envelopes for even more interesting modulations.
Two sample & hold units in one module for generating stepped random voltages or slicing signals
Notes: Module A-148 (Dual S&H) has two identical sample & hold modules, designed to produce 'staircase' voltages. The signal present at the sample input is sampled at a rate set by the signal at the trigger input, and held at that voltage at the S&H output.
The exact shape of the staircase depends on the sort of waveform at the sample input: NOISE or RANDOM signals produce random patterns; an LFO produces rising or falling staircase patterns.
Two LEDs for each S&H indicate the voltage (positive or negative) of the sampled signal.
Simple & effective voltage-controlled frequency divider - 8HP
Notes: Module A-163 is a voltage controlled audio frequency divider. The frequency of the input signal (preferably the rectangle output of a VCO) is divided by an integer factor N (N = 1, 2, 3, 4 ... up to 32). N can be adjusted manually and modulated with an external control voltage (e.g. from LFO, ADSR, Random, MIDI-to-CV, Theremin, Light-to-CV, analogue sequencer) with attenuator. The control input has polarizing function, i.e. the manually adjusted dividing factor can be modulated upwards or downwards. The basic idea of a polarizer is described in the modules A-133 Voltage Controlled Polarizer and A-138c Polarizing Mixer.
The output waveform is rectangle with 50% duty cycle. Unlike the A-115 with fixed dividing factors (2, 4, 8, 16) the dividing factor of the A-163 is voltage controlled and can be any integer value between 1 and about 20 (but only one output). In contrast to A-113 the dividing factor of the A-163 is voltage controlled and the output waveform is rectangle (the A-113 has 4 sawtooth outputs with 4 adjustable but not voltage controlled dividers).
Synth module featuring two separate voltage processors
Notes: The upper voltage processor features four inputs which are mixed and inverted at the output. Inputs 2 and 4 have their own attenuator. Input 2 is normalised to a positive fixed voltage source, which may be attenuated, and appears inverted at the output, useful for applying negative offsets.
The lower voltage processor features two inputs which are mixed and inverted at the output. Input 2 has its own attenuator. Input 2 is normalised to a negative fixed voltage, which may be attenuated, and appears inverted at the output, useful for applying positive offsets.
Dual trigger modifier, consisting of two trigger inverters for gate, clock or trigger signals - 4HP
Notes: Module A-165 (Dual Trigger Modifier) contains two separate trigger modifiers, to use with logical/digital levels (gate, clock, trigger). Each half of the module enables signals generated by the A-100 to communicate with other instruments (such as an external sequencer) or is simply used where you want to reverse a trigger polarity.
Whatever signal is patched into the input, inverted by the module, and fed out of the Inv. Out (inverted output) socket. At the same time, a trigger signal of roughly 50 ms is generated every time an edge of the trigger pulse is sensed (negative as well as positive). This trigger signal is available at the +/- output.
Two LEDs act as indicators showing the level of signal available at the two outputs.
When both units are daisy-chained the module can be used as level shifter for gate/trigger/clock signals (from min. +2,5V up to +12V)
Two independent voltage controlled switches in one module - 4HP
Notes: Module A-150-1 (Dual VCS) contains two separate voltage-controlled switches.
Each switch has a control voltage input, a common Out / Input, and two In / Outputs. The switches are bi-directional: they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. Voltages in the range -8V...+8V at the O/I resp. I/O sockets can be processed by the module.
Two LEDs show which in / output is active (i.e. which is connected to the common out / input).
Notes: A-149-2 is an extension module for A-149-1. It makes available 8 digital random voltages (i.e. only low/high states like a gate signal). The outputs are controlled by the "Quantized Random Voltages" section of the assigned A-149-1 and correspond to the 8 digital outputs of the shift register that is used to generate the Quantized Random Voltages. As the alteration of the A-149-2 outputs is clock controlled by the Clk In of the "Quantized Random Voltages" section of the A-149-1 the A-149-2 can be used to create random rhythmical sequences.
The A-149-2 requires the A-149-1 and has to be mounted directly to the left or right of the A-149-1 as an internal ribbon cable connection has to be established between A-149-1 and A-149-2.
Frequency divider for clock, trigger & gate signals - 4HP
Notes: Module A-160 is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses. The Trigger input will take clock signals from, e.g. an LFO, MIDI sync, or the gate from a MIDI-CV interface.
At the outputs, you have access to the sub-divided clock signals, from half the clock frequency down to 1/64. The low/high levels of the output signals are 0V and about +10V.
The A-160 also has a reset input. Whenever a reset signal is sensed, all outputs are set to zero, until the reset voltage disappears.
The Clock Divider can be used in combination with the A-161 Clock Sequencer to produce stepped sequences with a length of from one to eight events.
Notes: Module A-161 is an eight-step Clock Sequencer which is internally connected to the Clock Divider (A-160). Eight outputs are sequentially switched by the clock signals from the A-160 (see Fig. 1) and can act, for instance, as sequential rhythmic triggers for an envelope. The reset on the A-160 also works on the A-161 (instant return to Step 1). The low/high levels of the output signals are 0V and about +10V. In combination with a mixer (A-138) short analogue sequences can be generated. Our MIDI-Analog-Sequencer MAQ16/3 is suitable for MIDI-controlled analogue sequences up to 48 steps. A "real" analogue sequencer with 8 steps is the A-155.
Voltage-controlled clock multiplier with CV or manual control - 4HP
Notes: Module A-160-5 is a voltage controlled clock multiplier. The incoming clock signal (socket Clock In) is multiplied by a factor that depends upon the control voltage on socket CV In (0...+5V) and the position of the Mode switch. The multiplied clock signal is available at the socket Clock Out. According to the position of the Mode switch different clock multiplying factors are assigned to the control voltage. With 0V CV no clock output is generated. This state is indicated by "all LEDs off". With increasing CV integer factors (left position of the mode switch), power of two factors (middle position) or a mix of both (right position) are obtained. Nine LEDs are used to show the currently selected multiplying factor. In addition two LEDs are used to display the incoming and outgoing clock signal.
A manual control is used to adjust the clock multiplication factor manually without the need of an external control voltage. The voltage generated by this control ("Manual") is normalled to the CV In socket. As long as no plug is inserted into the CV In socket the clock multiplication factor is adjusted by means of the manual control knob and displayed by the LEDs. For dynamic applications (like the ratcheting function described below) the manually generated CV is overwritten by the external CV which has to be fed into the CV In socket.
The module can be used for all kind of clock multiplying applications. One important example is the generation of so-called ratcheting sequences. The band Tangerine Dream is famous for this kind of sequences. A normal sequencer generates only one gate signal per step. A ratcheting sequence may have also more than one gate pulses per step. This function can be obtained by using the A-160-5: one CV output of the sequencer is used to define the number of gate pulses per step. If the control of the step in question is fully CCW the generated CV is 0V and no gate signal is generated (mute of the step). When the control of the step in question is turned clockwise one, two or more gate pulses are generated depending upon the position of the mode switch and the voltage generated by the CV at this step.
Technical note: Due to the nature of clock multiplying it takes a few input clock pulses until the clock output is stable. One has to average a few input clock pulses to generate the multiplied clock output signal. Even when the input clock frequency changes it will take a few cycles until the output clock signal is correct as the module cannot foresee the future of the clock input signal. The generated clock output signal is derived from the last few cycles of the clock input signal. Consequently the module should be driven only by a clock signal with constant or slowly changing frequency.
Notes: Module A-162 contains two identical circuits that generate a trigger signal with adjustable delay and length from an incoming rectangle signal (e.g. gate, trigger, rectangle output of an LFO or VCO). The rising edge of the incoming signal is used to trigger the new trigger signal. This module makes it possible to delay the onset of a trigger pulse, and also change its length.
On each of the two units, two controls can alter the onset time and duration of triggers, from about 2 ms up to more than 10 seconds. A control LED shows the generated signal.
Notes: Erica Synths Black Multi is highly accurate active buffered 2x1to3 or 1to6 multiple that will work for signal splitting in any circuit, including driving several VCOs in tune from one CV source. "Octave" or +/- 1V offset switches on both channels allow to add or subtract one volt form each channel thus transposing VCOs one octave up or down. Hidden feature - custom offset - allows to set user defined offset on the first channel.
Notes: The Bass-522 module is based on the 522 circuit and offers a punchy attack, long decay and wider pitch range. Adjustable noise and pitch envelope have also been added.
The sound can be triggered by Gate, M-Bus and signals like piezo pickups, dynamic mics and drum pads. The Sense parameter decides the sensibility and dynamic of attack, amplitude. decay and pitch.
The following parameters are available and can be controlled by CV:
TONE dampens the attack transient.
DECAY sets the release time of the amplitude.
TUNE defines the basic pitch from around 35 to 70 Hz.
PITCH controls the amount of pitch envelope.
NOISE mixes the noise floor (no CV control).
The module offers the new developed M-Bus connector which means you can you control everything via MIDI/CV interface or the new MFB SEQ-01 Pro Drum Sequencer without additional patching. The following addresses are supported:
Trigger with Velocity - MIDI Note #35 or #36 (switchable) and controller values for Tone, Decay, Tube, Pitch and Noise Decay.
Notes: The ADSR module is a voltage-controlled envelope generator. Normally, the characteristic is logarithmic, but a linear part can be added. With the help of the loop button, the envelope can also be used as an LFO, then Attack and Decay determine the frequency that goes far beyond 100 Hz. Another special feature is the CV inputs for Attack, Decay and Release. This can be used e.g. control or modulate the times externally. In addition to the normal output, there is an inverted output in parallel.
The power consumption is +/- 30 mA. The module has a width of 8 HP (40 mm).
Notes: The 24dB VCF SSI is a voltage controlled analogue low pass filter module with the new SSI2144 chip. In addition, it has a 12dB output that works either as a low pass or bandpass (+/- 12dB). There are two inputs, one with attenuator. Another CV input with attenuator is available for the cut-off frequency. The resonance is controlled either via a controller or via another CV input with attenuator.
The power consumption is +/- 30 mA. The module has a width of 8 HP (40 mm).
Notes: The DRUM-99 module is an audio-mixer that has been designed for the modules of the MFB-DRUM series but also for usage with other manufacturer's modules. When using multiple drum-modules in a modular system, the following processing stages like filters or VCAs often lack enough audio inputs. To route a complete drum-set through a filter, a separate mixer like the DRUM-99 comes handy.
DRUM-99 offers five monaural inputs with individual level control. Tiny trim-controls are used to set the channel panorama position for the internal stereo-bus.
A fixed level stereo-input can accommodate the signal of one or more additional DRUM-99 modules. These inputs can also be used with the DRUM-06 module (Tom Tom) that also offers a stereo-output.
All five mono signals and the stereo-input are routed to the stereo-output that can be connected to two VCAs, filters or other sound manipulating devices. The output may also be used to connect the DRUM-99 to a mixing-console or audio-interface.
The stereo-output is designed for a possible summing with additional stereo-outputs.
Notes: The VCO/DCO is a voltage controlled analogue oscillator module. This can also be used as a DCO, eliminating the need for heating and temperature sensitivity. All functions except for the FM input are also available with the DCO. Sawtooth, triangle, rectangle and pulse are available as waveforms, with soft switching between the individual waveforms. This can also be done with a control voltage, so you have additional PWM modulation.
The power consumption is +/- 30 mA. The module has a width of 8 HP (40 mm).
Voltage controlled LFO, switchable to oneshot mode
Notes: The module VC LFO accommodates a slowly oscillating oscillator, which is primarily used for modulations. It has five waveforms, CV input with attenuator and a control range from 10 seconds to 100 Hz. In addition, the LFO has its own reset input, over which the waveform is restarted. If you set the speed accordingly and have a separate reset pulse, you can synchronize the LFO with a sequencer. The following waveforms are available: rising sawtooth, triangle, falling sawtooth, rectangle and sample & hold.
The output voltages are maximum +/- 5 volts. The module has a width of 8 HP (40mm).
Clap module based on circuit designs of the MFB-522 & Tanzbar Lite
Notes: The Clap-522 Modul contains an enhanced circuit of the MFB-522 and Tanzbar Lite. You can edit and modulate the sound in a wide range.
As modular concept you have the possibility to control the parameter PUSE, SNAP, ATTACK, DECAY and FILTER via CV-signals from Envelopes, LFOs and Step Sequencers.
The parameters are in detail:
PULSE is the amount of claps between 1 and 7.
ATTACK sets the noise level between the clap repetitions.
DECAY controls the release of the noisy reverb.
FILTER defines the colour of the noise floor.
WIDE edits the gap between the single claps.
Beside sequencer generated analogue and digital trigger-signals, drum pads, piezo pickups and dynamic mics may also be used. Here the SENS controls allow individual adjustment of the input sensitivity. Dynamic trigger also changes the volume of the clap.
The module provides the new developed M-Bus connection. MIDI signals can control following destinations:
Trigger MIDI Note #39 or #82, switchable, with Velocity. Controller values for Wide, Attack, Decay and Filter.
B-STOCK: Box opened, product in perfect working order
Notes: ***B-STOCK: Box opened, product in perfect working order***
TOPOGRAF is a drum sequencer with three tracks, that works with a "topographic" principle; it contains a number of drum patterns arranged in a "virtual map"; and with two knobs MAP X and MAP Y you can set a position in this map. With one knob per channel the density is defined; and a CHAOS knob brings some randomness into the whole process. All in all, a few knobs for a lot of drum patterns you probably wouldn't make this way by yourself - a nice source of inspiration and also great for playing live.
TOPOGRAF is the AE modular version of the Grids module by Mutable Instruments. It is 100% identical to Grids.
