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. 

Sampling mode: 
- 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) 

Wavetable mode: 
- 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. 

Effects: 
- 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).
