Doepfer A-112

Sampler / Wavetable module

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.
