“Studio use only Yamaha cs-70m 6 dual voice programmable synthesizer with built in sequencer. Successor to the CS80, used by everyone in the early 80′s. Great cosmetically, everything works, all the leds light up. I have the manual and the magnetic sound strips. A very big, heavy, fragile machine do pick up only in London. ” Link
“If you have a CS70 then you need these preset cards. Guaranteed to work. There are 29 cards, each with an “A” side and a “B” side.

They are identified as follows: clavichord; brass ensemble; organ I; string ensemble; delayed harpsichord; bell electric piano; percussive synth; breathy flutes; organ II; jazz guitar; vocal ensemble; poly sample/hold synth; laser shots; ring modulation; laser filter sweep; brass/clav; EG mod + VCO; string ensemble; flute; VB3 lower; B3 upper; funky; string II; brass; pitch bend clav; clavinet; space cadets; string quartet 1; string quartet 2; S+H bass; sync. I; shock the monkey b.p. B flat blast; shock the monkey B flat blast (lo); talk to ya later fugue solo; as pete a. use unison (?); talk to ya later echo-brass; harpsichord delay; shock the monkey brass 16′; shock the monkey brass 8′; shock the monkey steel drums 1; shock the monkey steel drums 2; steppin’ out attack bass; steppin’ out bass release.” Link
“Yamaha cs 70M 6 voice analog synth circa1981, this synth has been worked on a lot but still has a couple of issues, I can send a scanned copy of the techs notes if requested. The synth is in good condition for its age with a few scratches/scrapes and dents/dings here and there but not to bad at all given its age. There are no broken knobs or controls and all 61 keys do sound. Auto tune disables the 6th voice and then wants to tune it a 5th higher than the rest, and the tech could not resolve this issue, but he informed me that it most likely could be with more time and money spent , which I did not want to do, the synth sounds and plays great to me and and the voice issues were not apparent to the end user , unless you specifically were looking for them, as all 12 oscillators two per voice are working, and the memory is working perfect. The synth does come with a flight case and power cord and a copy of the manual/servicing notes. Some call these a poor man’s CS 80??? I don’t think so at all this is a big and beautiful sounding vintage analog synth totally and they are becoming very scarce anymore. You can get some great string sounds out of this cs-70M, and it has a poly-sequencer onboard as well. ” Link
“Vintage Yamaha CS70M analog synthesizer.
This example is in non functional condition but complete.
Does not power on, all voice boards in place, no missing PCB’s.
Currently i have no time to invest in this machine so i leave it to someone else.
Overall front panel looks good, side panels look a bit used. Its keyboard is straight..
My last CS70M sold last week within 1 day for more 3k+ so get your chance to make some profit.
This item is SOLD AS IS, broken for parts or repair.” Link
“Und hier ist Nr. 2 dran. Unser Yamaha CS70M. Wir hatten die Möglichkeit, den Vorgänger des CS70M für unser Tastronauten-Studio zu bekommen und müssen das leider durch den Verkauf einiger Stücke finanzieren.
Der CS70M klingt durch eine kleine Modifikation noch eine ganze Ecke besser, als er ohnehin schon klingt. Die Modifikation ist in wenigen Minuten reversibel. Es wurde dafür nichts gebohrt, keine zusätzlichen Schalter o.ä. eingebaut. Wenn ihr wollt, machen wir das für euch. Ich würde euch aber raten, die Modifikation (von außen unsichtbar!) beizubehalten. ” Link
“Purchased 10 years ago. Was working when I bought it for home use. It has been in storage for 8 years (that is how the key became broken). I believe that the Bridge Rectifier on the PSU has blown (shown in the photograph with a replacement). Unfortunately, no time or interest to fix it hence the sale. ” Link

“Biete hier einen von meinen Yamaha CS70m Synthesizern an.Viel dazu brauche ich wohl nicht dazu zu schreiben.Diese Rarität ist auf der ganzen Welt kaum noch zu finden.Wer die astronomischen Summen für einen CS-80 nicht ausgeben will,ist mit dem jüngeren Bruder auch bestens bedient.Mir persönlich ist der CS70m lieber,da die Tastatur im Gegensatz zum kaum spielbaren CS-80 hervorragend ist und der Klang-Eingriff und die Änderung der Parameter mit dem CS70m besser von statten geht.Der CS70m ist in einem sehr guten Zustand und fristete sein Dasein in meinem Studio und hat auf der Front keine sichtbaren Kratzer.An den Seitenteilen sind einige kleinere Blessuren im Rosenholz vorhanden,was sich leider bei dem Gewicht von 30kg nicht vermeiden lässt über die Jahre.Der CS70m funktioniert einwandfrei,ein passgenaues teueres Flightcase,die original Magnetstreifen im Lederetui,sowie das original Fusspedal,das z.b.VCA;VCF und VCO beeinflussen kann und bei dem der Gigant zum Erzeugen von unglaublichen Sounds herausgefordert wird,ist ebenfalls mit dabei.Am liebsten ist mir Abholung in der Nähe von Heidelberg.Ein Versand kann aber auf Gefahr hin für den Käufer,erfolgen.Zum Schluss das übliche:Keine Garantie oder Rücknahme für das gute Stück,da Privatmann.Viel Spaß.” Link
“up for auction is my yamaha cs70m.
she’s a very rare and beautiful sounding instrument. being sold in condition to sit down and immerse in her sonic goodness. everything works stable and in tune.
condition:
(see pics)
there were mods done to her:
1. Keycode Input (SK30 or SK50D connector) on the back was removed – done by org. owner
2. PGM lock (program write lock/unlock switch) was replaced w/ additional L/R outputs – never tested ‘em but if i remember correctly these outputs bypass VCA or VCF of the synth. (sorry may be wrong here) – done by org. owner
3. MIDI interface by Kenton was added by a Pro from “A Sound Education”, a shop here in Chicagoland.
they also turned her inside out to check for any problems: “Feet I” slider was cleaned and re-soldered, program switches 11 & 14 in row 1 were replaced. midi was implemented and tested. no other issues were found.
the wooden panels are chipped/worn in few places, especially on the edges. the metal faceplate has no scratches or prints missing on it.
the case provided has a dent on lower lid and is low quality, so to speak, but will help ship her safe.
also included in this auction are: printed Owner’s Manual, printed Troubleshooting Guide, Kenton Midi Manual/Diagram, 2 large Diagrams of Analog and Digital blocks and a bill from her recent stay at “A Sound Education”. ” Link
