A µP controllable dual waveform converter/processor from Curtis ElectroMusic Specialities.
Features:
from the original data sheet
complete sound synthesis system on a chip: two multi-waveform converters, a 4-pole VCF, a VC mixer and four VCAs
0 to +5V high Z control inputs for direct interface to CMOS multiplexer from system DAC
few external components
numerous waveforms and combinations for more timbral variety
independent and continuously variable waveshape and pulse width for each converter
filter FM
constant output vs. resonance VCF characteristic
open loop VCF design for rich sound
low noise, low IM distortion VCAs
choice of linear or audio taper VCA control scales
low VCA feedthrough without trimming
