The Yamaha CS-01 is a 1982 monophonic synthesizer featuring a single VCO with PWM, a 12dB/ Octave resonant filter, an ADSR envelope generator and a small built-in speaker.
The CS01 is a very old but classic analog monosynth from Yamaha. Although originally designed for use by novice musicians or first time synth-buyers, the CS01 has been recognized by today's electronic musicians as one fat little bass machine with simple controls. In a nutshell, the CS01 is simple to use and edit but still has some great features for any situation. It's tiny and portable, it has baby-sized keys and it can run on batteries, and there is a built-in amplifier and speaker which is quite fun.
As for sounds and synthesizing, the CS01 is the perfect monosynth for bubbly and growling bass! It features a very nice 12dB resonant voltage-controlled filter. In addition to the oscillators' sine and square type waveforms there is PWM and noise. There are also LFO controls, glissando (like portamento), a typical ADSR envelope generator, pitch & mod wheels and even a breath controller input. A CS01 mkII was later released by Yamaha soon after the original. It featured an improved 24dB resonant VCF (filter) with adjustable slider control over resonance instead of switchable on/off resonance as found on the original. The CS01 mkII is also identifiable by its black case with green letters.
