via this auction."The Yamaha CS01 Mark II improves upon the first CS01, which is itself a classic instrument. This is a true analog synthesizer with mini keys, very stable with no oscilllator drift like the minimoogs used to have, sliders for LFO, VCO, VCF, VCA, and EG with individual sliders for the parameters of each of these. There's an input for a Yamaha breath controller, which can control either VCF or VCA , plus wheels for pitch bend and modulation (assignable to VCF or VCO)."
