” Great used cosmetic condition. It turns on, boots, but will not load any sounds. We replaced both internal batteries, but that did not fix the problem. This board can be used for parts for another repair, or one could possibly fix this one up easily… maybe.” Click here to visit listing on eBay

“YAMAHA SY99 Synthesizer workstation FM AWM2 with Viking case. Condition is “Used”.
You know about the amazing sound of the SY99. That’s why you’re here. This one is in good condition. No cracks, or whatever. The drive (as with 90% of them) doesn’t work. There is an aftermarket emulator drive. I had it, but can’t find it. 🙁 It also says something about the wave memory battery needing to be replaced. All the preset sounds function perfectly, and that’s all I ever really wanted from this beast. Those sounds! I bought this one used. I had a brand new one in 1992, but it was lost/stolen/sold/other… (don’t remember). I have had this current one at my house for a few years now, but I’m moving to an upstairs one bedroom apartment. SY99 can’t come… not carrying it upstairs! Please, buy this gorgeous sounding instrument and record with it. You’ll thank me. You’ll have sounds that no one else can recreate!” Click here to visit listing on eBay

“Nice Vintage Yamaha Model SY99 Polyphonic Digital Workstation / Synthesizer / Sequencer Keyboard.

It has some dings and signs of use but otherwise is in good condition for its age.

It does work – I tried all the buttons and keys but I am not a keyboardist so I cannot test every function on this keyboard as there appears to be a zillion setting permutations so I am selling it AS-IS – For Parts or Repair. ” Click here to search for synths on eBay
