I'll sell mine.. I have an old Pss-680 I found in my Attic when i was cleaning last week..I got it when I was in high school.. The power cord is missing and the battery cover is gone so I used an adapter from my Cable PC Modem and it turned on..

The keys seem to all be working, the percussion pads all work and from what I've tried, all the other buttons including the voice and style etc.. seem to be in working order.

The the volume control is a bit glitchy if you try and move the slider all the way up, the speaker cuts out, but if you move it down just a bit, it's fine.. The left speaker isn't working, the right speaker seems to be working fine..

But all in all, I'm sure no one would find it hard to get a suitable power cord to fit it and if you connect it to external speakers, the left internal speaker not working would not be a problem..

Maybe someone who fixes keyboards could check it out and repair the minor problems with it..

If anyones interested, email me at and make me an offer..

The Yamaha PSS-680 keyboard is a cool little keyboard. True, it is not as sophisticated as some of the more expensive synthesizers, and yes, now that I have gotten used to using the normal size keys on keyboards, the keyboard keys do seem to be a little cramped. And the sounds are not realistic and there are some limitations on the drum machine. But for all its shortcomings, I still like it. I have other keyboards that I use for music composing that sound like live orchestras, but when I like to create sounds from scratch using the on board synthesizer features, I can get some really neat and far out sounds. It still makes for a good cheap synthesizer especially since I don't have large money. It has full modulations -- attack, decay, feedback, and so forth and I like to play around with these just to see what I can come up with. In fact for a low end priced keyboard, it actually has features that my newer keyboards seem to be lacking and I haven't seen even in more expensive keyboards. Feed its audio output into a stereo system, and it sounds fairly good.

I even gotten quasi animal sounds out of it!

The PSS680 was my first step into digital synths, and was a central player in two of the bands I was involved in:

Impact, a keyboard duo

Syntheosis... a synth-based rock band.

In Syntheosis, it povided a lot of the backings and lead lines. As a controller, it is the most versatile synth I've ever used; I've had up to four instruments connected to the MIDI out, making great use of the multitimbral output.

At its introduction, it was really advanced for its time, and when it finally stopped working I was sad to see it go! The small-key format led me to produce some really fast lead-line work and some unusual chord colours; single handed 5 and 6 note chords not possible using large keys unless you have gargantuan hands! Other outboard devices include an Atari ST (with sequencing and patch editor software (Bryan Kennerley's PSS-Ed). We used the onboard sequencer to produce some nice sequences "on the move" in the middle of performances, where countermelodies and harmonies were required. The instrument's controller could be used to control external instrumentation whilst muting the internal fm sounds, allowing clever use of polyphony, which was 12 notes maximum on the 680. The instrument taught me a lot about music sequencing, and I achieved aq lot with such a small outlay! about programming!
