The CS70m is a great big powerful polyphonic analog synthesizer which belongs to Yamaha's excellent line of CS series synthesizers. Fat sounds, cutting leads and bubbly basses, the CS70m has 6 voices of polyphony each supported by 2 oscillators for a total of 12 analog VCO's! It's got very flexible LFO, envelope and filter controls all of which sound really nice and smooth. The VCF (filter) has its own independent envelope control as well.

Truly a lush sounding instrument that would please anyone looking for that J.M. Jarre or Tangerine Dream sound. Other features include a 4 track polyphonic sequencer, a 5 octave keyboard with aftertouch sensitivity and external magnetic data card memory storage. With only a slim 30 preset sounds that are mediocre, this is the kind of synthesizer that begs you to grab its knobs and start editing (that could possibly explain its big flashy knobs and buttons).

All in all an excellent and large synthesizer that will make any synthesist happy! It has been used by Kajagoogoo. The next step up from this synth is Yamaha's CS-80 which is an eight voice monstrous beast quite similar to the CS70m. The CS70m is likely to be too large for anything more than studio use but if you can find one it is definitely worth a listen!

If you're looking to sell I'm interested in buying (I've posted a few times trying to make a transition from to analog). Contact me at pablojaekwon1985@hotmail.com

Picked one of these up recently (Jan 2010) - you can check it out here:

Would love to put one of these next to a CS80 and see what the real deal is. I played one years ago; I was young, impressionable and totally blown away. I've been looking recently. With the CS80s over 10K this might be a good alternative. Plus I can control it with my CP-35. Weighted action in a vintage analog beast... how cool would that be? Well, I guess as cool as a T8 or a Chroma.
