Yamaha SY22

“Yamaha SY22 Dynamic Vector Synthesizer Keyboard w/ box, power supply.

Yamaha SY22 with rare Stage Selection expansion card. Keyboard uses vector synthesis. Has no filter but to honest. I didn’t miss it because the way you can blend sounds. Surprisingly has more unique waveform then I expected. Especially with the expansion card. YouTube videos don’t donit justice. A lot more going on under the then people show.

The bad: Output left & right does not work but, the phone output does with any problems. No static or crackle.” Click here to visit listing on eBay

Yamaha DX27

“Yamaha DX27 Used Keyboard Synthesizer Synth Programmable Algorithm Used As is.

Comes with a euro ac adaptor with US plug converter but powers up with no issues.

I plugged it in and functions and switches appear to work but I’m not an expert. The absolute highest key seems to be a little wonky so you’ll probably have to hit it with some contact cleaner.

Keep in mind that we are offering this for a discounted starting bid and there are plenty of serviced examples out there. Buy this only if you’re a tinkerer/pro that knows how to maintain vintage synths. With a small bit of effort you can have a great player synth for a fraction of the price of a serviced one. ”

+ a dedicated complete guide by Yasuhiko Fukuda
+ a separate Sound Patch Library book with hundreds of additional programmable sounds
+ a Voice Library catalog with accompanying Performance Notes
+ both original sound cartridges
+ a DX-ROM 128-voice third cartridge that I purchased separately
+ a blank cartridge (with some additional loadable voices).
+ Voice data list sheets for recording your own NEW voices
+ Gotcha Covered custom-made dust cover
+ two original equipment cassettes: “DX Performance Demonstration” and “The DX Zone”
+ an original equipment Breath Controller

I can provide additional pictures for lists of patches and everything else!

But we’re not done.

The flight case alone cost $400 (1985 dollars!) and it is designed to protect your instrument under extreme handling conditions.

This bundle is an exceptional deal, given the total cost of individual items purchased separately (and the trouble of piecing together everything)!” Click here to visit listing on eBay

Yamaha DX7s

” Yamaha DX7S Digital Synthesizer Keyboard. Working and in good, clean condition. Includes 1 cartridge, volume pedal, music holder, and soft case.

Functionality:

All 64 of the cartridge voices function perfectly
The “internal” voices show unreadable special characters on the screen, and not all of them play a sound. Those that do are special effect type sounds vs instruments
I tested the headphone and 1/4″ outputs, as well as the volume pedal – all working fine. I do not have a way to test the MIDI ports” Click here to visit listing on eBay

Yamaha CS15

“Yamaha CS-15 Vintage Analog Monophonic Synthesizer Working – GREAT!
Absolutely lovely and fat sounding synth! My favorite on my collection, that’s why it’s so hard for me to sell it but I have to let it go.
Physical condition is 7.5/10.
This synth has two of everything (oscillators, filters, envelopes, etc). The first filter is a bit noisy and crackly, but I’ve being using the second filter and that has worked for me. If you want an absolutely perfect working synth, you will have to take it to the synth doctor. Otherwise, great!” Click here to visit listing on eBay
