Yamaha CS01

Yamaha CS01 Image

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.

Does anyone know what kind of signal the breath controller input is responding to? I don't have a breath controller and would like to use an alternate means of control. For instance, I use a Casio VP-2 pedal to affect the VCF on my Juno-6. I tried the same pedal on my CS01 without any luck. There was some effect but it was very slight. Would a similar Yamaha pedal work?

My CS01 has MIDI but I'd like to be able to mess with the sound while the sequence plays. Unfortunately my hands are usually busy on another instrument. HELP!!

Got my cs-01 mk1 for christmas as a kid back in 1983. Damn love it. Too bad it is now in need for service.
Second thing I need to get out of my system is that people who keep on moaning about the uttermost importance of how a sound is created, they freaking annoy me! Analog, digital, DCO or VCO. Why care?!?!?

I own it. I use it. I love it. I have the mk1 and get a variety of excellent bass tones out of it. Everything from nice subtle rolling analog lines to big punchy dancehall stabs. Also some nice theremin-like leads for the homies. Mini keys are super playable after some practice and the women love the waves and ocean sounds after love making.
