A
duophonic analog synthesizer with a 44-note
keyboard. Manufactured between
1979 and
1986.
The CS-40M contains 2
VCOs, which are switchable between
triangle,
sawtooth and
square (
pulse)
waveforms. They offer a 6-
octave range,
fine tuning,
PWM plus their own AR envelope generator. A
white noise generator is also included.
As the
filter there is the model you find in just about every CS-series synth: a
resonant* 12
dB/
octave** multimode
VCF which can be switched between high-, low- and band-pass. Controls for cut-off, resonance and keyboard tracking are available, as well as an individual
ADSR envelope.
The
VCA features its own ADSR EG, plus a mixer section for VCO1, VCO2 and noise.
The
LFO is switchable between
sine,
ramp up/down, square and
sample/hold. It can modulate up to the
AF range.
Internal
memory is available on the CS-40M, and can hold up to 20
patches. There is also a
tape interface for more storage.
Wheels for both
pitch bend and
modulation are included, as well as
portamento. The keyboard can be set to
unison mode, stacking the two
voices together.
Both voices have their own CV/
trigger outputs. CV
inputs include portamento, sustain,
brilliance,
volume and filter.
