The A-112 Module is a combined module of a voltage-controlled 8-bit sampler and a wavetable oscillator. Moreover, it is able to produce effects. It is available as a supplemental sound generator module for the A-100 with the characteristic sound characteristics of the early 8.Bit samplers and cannot be compared with commercially available MIDI samplers!

"Sampling mode: "

8-Bit audio resolution , 128 kB memory in 2 banks (S1, S2) of 64KB each (this corresponds to 2 seconds sampling time at 32 kHz sampling frequency), audio input with attenuator, overdrive display in recording mode (gate LED) Dump capability to archive sounds, non-volatile memory for the samples in the module, manual tune control to adjust the sampling rate during recording and playback, the CV input (1V / octave), along with the tune control The sampling rate or pitch (pitch 5 octaves corresponding to 0 ... 5V, pitch resolution 1/4 semitone), gate input (no pure trigger, but the sample is started at the positive edge and runs until the Gate input becomes "high" or the end of the sample is reached), manual gate button, unfiltered audio output (ie, quantisation sounds can be used for sound generation).

Wavetable mode:

A special form of sampling mode, with the audio input acting as a control input for the sample which is stored in one of two banks (S1, S2) with 64 kbyte of memory each. In wavetable mode each bank is arranged as 256 pages of 256 bytes. The wavetables are loaded in the sampling memory (normally loaded via MIDI dump), thus making a wavetable oscillator, in which different waveforms (with different harmonic content) are traversed by CV2. With this mode of operation, however, a "normal" sample can "pass through", which sometimes results in quite astonishing sounds (interesting for the "passing through" speech, where the language spins very extreme sound structures).

Effects:

In addition, the module offers - as a free "extra" so to speak - some effects such as delay, reverse delay, pitch shifter and freeze. It should be stressed, however, that these effects can not be compared with the result of high-quality effectors due to the 8-bit resolution and should only be understood as a free-of-charge addition for bizarre sounds.

Module A-120 is a voltage-controlled 24 dB low-pass filter, which filters out the high frequency components from a sound spectrum while allowing the low frequencies to pass unhindered. The cut-off frequency (corner frequency) determines the point at which this effect occurs. They can be set or modulated both manually and via control voltages (filter modulation, with an LFO for example). The VCF1 is configured as a "transistor cascade" with an edge slope of -24 dB / octave, which is also used in various Moog synthesizers, This results in the typical, "legendary" Moog sound. The resonance (emphasis) can be adjusted at the VCF 1 to the point of self-oscillation. In this case, the filter operates as a sinusoidal oscillator.

The module A-140 is a envelope generator and since it delivers control voltages, belongs to the modulation-modules. As soon as the ADSR is triggered at gate-input, it generates an adjustable control signal called the envelope. This envelope is present on its outputs in normal and inverted S-form and can be used e.g. for modulation of VCO, VCF and VCA modules as well as for transient and decay oscillations of other modules. The S-form of the envelope is unambiguously defined by four parameters, attack, decay, sustain and release. The ADSR is triggered with a gate-signal at gate-input and provides the possibility of a retrigger-Function, i.e. the envelope will be restarted every time a trigger signal is present at the retrigger-socket while the gate is active.

In connection with the comparator-module A-167 a free run "ADSR-LFO" can be realised.
