# Yamaha CS-15 with Mochika Sequencer
“Up for sale is a Yamaha CS-15 bitimbral analog monosynth, along with a hand-built Mochika analog sequencer (search ebay for others, I believe he still sells them here). The synth is fully functional and was serviced about a year ago, there is a small dent on the top of the keyboard but it has been checked out and is 100%. The Mochika provides an 8-step cv/gate sequencer that can be synced to a click input from a trigger or old analog drum machine (would go very well with a 606 or similar), and effectively makes this the equivalent of a CS-40. Each CS-15 oscillator has it’s own CV input and it can be set up to run as a dual monosynth given the two vcfs and vcas. There is also an audio input which is run through the filters and can be used as a trigger. Run your bass drum through the highpass filter and it’ll blow out your speakers. I really can’t say enough about the filters here, they’re just liquid smooth. Pains me to let it go, but I’m moving and a buddy is offering me a great deal on an SH-101 so it’s time to pass it along. ” Link
