Module A-112 is the combination of a voltage controlled 8 Bit Sampler and a wavetable oscillator. On top of it the module is able to generate some special effects.
A-112 was designed as an additional sound source with the typical sounds of the early 8 bit samplers and is not comparable with the modern polyphonic MIDI samplers available on the market.
- 8 bit audio resolution,
- 128kB memory in 2 banks 64kB each (equivalent to 2 seconds of sampling time for each bank with 32 kHz sampling rate),
- audio input with attenuator,
- overload display in record mode (gate LED),
- possibility of MIDI Dump to store sounds in a computer via MIDI,
- non volatile memory for the 2 samples in the module,
- manual tune control for adjustment of sampling rate for record and play,
- CV input (~ 1V/Oct),
- both manual tune and CV determine the sampling rate respectively the pitch (pitch range is 5 octaves),
- gate input (not a trigger: the sample starts at the positive edge of the gate signal and is played as long as gate is high or until the end of the sample is reached),
- manual Gate button,
- non filtered audio output (thus quantizing noise can be used as an element of the sound intentionally)
- special appearance of the sampling mode when playing a sample,
- the audio input is now used as a second control voltage input for moving through the sample in 256 byte wide loops (wavetables).
- To achieve the typical wavetable oscillator sounds the sampling memory must contain corresponding wavetable data (normally loaded via MIDI dump). These data contain a set of wavetables with different harmonic content (e.g. a filter sweep) to get the typical wavetable sound while moving through the tables via CV2. But you may also use a "normal" sample and go through the sample with CV2 to obtain partially amazing sounds never heard before.
- You may use for example sampled speech and go with CV2 through the syllables or speech shreds to get really very extreme sounds.
- An ideal addition for this feature is the Offset/Attentuator module A-183-2 which can be used to adjust the position of the wavetable (Offset) and the modulation depth (Att.).
- As modulation source an LFO (A-145, A-146, A-147, A-143-3), ADSR (A-140, A-141, A-142, A-143-1/2) or a random voltage (A-118, A-149-1) may be used. Even a ribbon controller (A-198 or R2M), the Theremin module A-178, the Joystick A-174 or the Wheels module A-174-2 are useful to drive through the wavetables.
- Additionally the module offers - in a way free of charge - some effects like delay, reverse delay, pitch shiftinng or freeze.
- But it has to be pointed out that due to the 8 bit audio reolution these effects are not comparable to high quality effect units and should be understand as an extra for nothing. The A-112 is not an effects unit !
The sampling time of the A-112 is about 1...30 seconds corresponding to a sampling frequency range of about 60kHz...2kHz (64kB@60kHz ~ 1 s, 64kB@2kHz ~ 30 s).
