Whereas the CS01 is barely more than
a synth-historical artefact, the CS33 builds on the
concept and is quite a capable little synth even by
today's standard. While it can do all sorts of
"bread and butter" sounds, its signature sounds come
from the PWM oscillator waveforms, twin linked
filter modes and the built-in distortion effects.
V2 has a smoother-working GUI,
re-designed layout, animated keyboard, better
stability in multi-core systems, etc.
Hahaha CS33 is available as a
freeware VST instrument plug-in for Windows PC.
