# Yamaha CS-01
“Still in excellent condition for its age and fully working. Pots and switches have been cleaned out and all work very well and still have a good feel
All keys function and trigger every time pressed. Battery cover fitted and no leakage inside the cover
The CS-01 is a very old but classic analog monosynth from Yamaha. The CS-01 has been recognized by today’s electronic musicians as one fat little bass machine with simple controls. In a nutshell, the CS-01 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 CS-01 is the perfect monosynth for bubbly and growling bass! It features a very nice 12dB resonant VCF 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. Some of the lead sounds are superb when a bit of external effect is used – reverb, delay and any other units you might have” Link
