via this auction"Although originally designed for use by novice musicians or first time synth-buyers, 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."Update: note the auction notes this is from 1976. CV! in the comments wrote in: "This is from 1981-82 I think, surely not 1976. They were giving these away when purchasing a Dx-7. It's DCO based but it sounds great and has a KILLER PW" VSE shows the date produced as 1982 for the MK1 and 1984 for the MK2.
