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 (pictured below) 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.

The CS01 may look simple or toy-like but it is still able to create cool little analog bass blips, bass lines and bass bubbles that are just perfect for today's electronic musicians. It has been used by the Dust Brothers, Underworld, OMD, Richard Barbieri and Chick Corea.

Also played by Mitchell Forman in the 1984 lineup of John McLaughlin's band. (Mahavishnu Orchestra). He could really wail on the thing!

For me, Jean-Philippe Rykiel is the #1 master of CS-01:

An analog synth with a digital sound (actually). The "VCO" is a digital counter and the waveforms are extracted from this and output through digital to analog converters. Subtractive synthesis yes, but is it not stretching it a bit far to say this is an all analog synth ?
