The Yamaha CS80 VS. CS70M - An Exploration of Two LEGENDS!

Please join us while we do a direct sonic comparison of these two classic Yamaha synthesizers. As is widely recognized, the CS80 is arguably the most legendary synthesizer ever made. Just under 800 units were produced at an MSRP of roughly $7000 each in 1978. Each weighs nearly 200 lbs. The CS70m was the digitally controlled flagship model of the follow up: CSm (m for memory) Series. It was released in 1981 at a retail price of just under $5000. We could not find the production total for the 70m (if anyone knows, please share in the comments!). However, like its sibling, I would guess that less than 1000 were made during its production run which ended in 1983 as Yamaha prepared to release the infamous DX7.

While they do not sound identical by any means, we hope this video demonstrates how incredibly under recognized the CS70m is within the CS Poly family and amongst vintage analog flagship synthesizers in general. It is the closest you can get to the CS80 in terms of feature set, voice architecture, and dual channel sound. For the prices people ask today for the CS50 and CS60, one would be smart to look for a 70m instead (IMHO!).

The audio is DIRECT, 100% DRY, & IN STEREO - You are hearing the raw audio as it comes directly from each synthesizer. NO post processing (Effects, EQ, or Dynamics) whatsoever.

Thank you so much for watching! This channel is a passion project. We are just two hobbyists who share a deep passion for synthesizers. Please consider subscribing, we would greatly appreciate it!

-The CS80 can also do bandpass filtering as the HPF & LPF are routed in series
-On the CS80, the sliders labelled: Sub Oscillator is the LFO
-The CS80 has 8 voices while the CS70m has 6.
