Yamaha CS-70m

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!

The sound were so thin that they designed a sine wave to go straight to the VCA to be mixed in for added voulme to the sound. Also it's not based on the amazing amount of components used in the old CS series (80-50). They cut corners in the M series and used many integrated components. The result was bad sound.

This review of the 70M is a joke. This synth has NOTHING in common with the previous CS series (80-60-50). The M series was the end for Yamaha in analog synths . They did not sell due to high price, very very poor flat and thin sound. And forget about getting MIDI in it. But anyway you can hardly find one for sale as they sold very few of them. DX7 came next fulll digital for good reason. They gave up on analog as they failed. I have played the CS70m & owned the 20 & 40M. They are nothing. The guy who has this page must have only seen the images of the CS70M and made his review based on this.

CS70M FOR SALE! You can hear this synth all over Boards Of Canada tunes. Yep, I'm selling this truly amazing poly. 12 gloriously warm VCOs, great modulation possibilities, the most astounding sub osc, brass etc. not to mention the killer uniso mode. This is synth has so much personality. I will miss her greatly, but really need the funds. Contact me: simon@jinadu.com

The german Tastronauten also use the CS70m. On their website www.tastronauten.de they have many good sounddemos of this synth and of many other synthesizers, too.
