A112 Vc
sampler/wavetable oscillator. 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: 8bit 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 (1Hz/V), both
manual tune and CV determine the sampling rate
respectively the pitch (pitch range is 5 Octaves, pitch
resolution is 1/4 semitone), 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. Effects: 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. Samples and wavetables are planned to be available at The Doepfer Homepage. Width: 10HP, Current: about 30mA, additional +5V/about 50mA required. |
