The CS-01 is a monophonic, single oscillator synthesizer with a 2 1/2 octave mini-sized keyboard, that can run on battery power or via external PSU. It was obviously marketed to the young, first synth buyer, market. However, dispite it's mini-sized keys, it has been since adopted by many professionals for it's simple design, active sliders, and great sound.
The CS01 outputs any one of several waveforms, as well as noise and PWM, along with a voltage gate signal that triggers the envelope generator. The waveform is then fed to the VCF, which features variable resonance, and then on to the VCA. There is a sub oscillator as well. The oscillator has a slider for fine tune, and another with four octave settings, with the fifth setting switching it to the noise source. Available waveforms are triangle, sawtooth, square, and narrow. There is also a separate slider controlling the PWM speed and a slider for glissando. The filter (12dB/octave) section has sliders for cutoff frequency, resonance, and EG (envelope generator) depth. There is a EG depth for the VCA. There is a switch for resonance (low and high only). The LFO can be switched to control the VCA or the DTG. There is a slider for LFO speed and the amount is controlled by the controller wheel. The envelope generator is a simple ADSR with sliders for each (attack, decay, sustain, release).
