Synth of the week : Yamaha CS-01


The Yamaha CS-01 is a classic analog monophonic, single oscillator synthesizer with a 2 1/2 octave mini-sized keyboard. It's tiny and portable, it can run on batteries or via a wall-wart AC/DC converter, and there is a built-in amplifier and speaker.
As It was marketed to the first synth buyer, it looks as a toy, but it has been since adopted by many professionals for its great sound.

The CS-01 features a very nice 12dB resonant VCF filter.



Sine, square, PWM and noise type waveforms.



LFO controls - glissando (much better an funnier as a portamento) - a ADSR envelope generator - pitch & mod wheels and even a breath controller input (wich has separate knobs for VCA and VCF amount).

A CS-01 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 CS-01 mkII is also identifiable by its black case with green letters.

The CS-01 did come with a cool carrying case.

I have one of these, and loved it except for one thing-- the filter resonance, even in the 'high' setting, is not quite wet enough. I wanted near oscillation! So, I went inside and changed the resistor value to gett it nice and wet in the h setting.
