” Yamaha DX21 digital synthesiser from the late 1980’s, in good working order.

Missing the tops to the slider controls – see photo, but the controls all work well.
Pitch and modulation controls both work fine.
The case on the left hand side has a crack”

“Selling a Yamaha DX11 in cosmetically very good condition. All keys, sliders, wheels, and aftertouch work. There is, however, a bugginess where some of the higher patches selected will go into a function or edit mode instead of straight to the patch. The workaround, I have discovered, is to press the “internal” button right after, to actually go to those patches. This occurs when choosing Bank B as well, and is remedied the same way. My guess for the permanent fix is to upgrade the firmware EPROM chip.

That aside, it’s a very clean board and it sounds great. Selling as is and asking for $100 cheaper than the current going rate considering the abnormal behavior.”

“This Yamaha DX7 was quoted by Randy Waldman as the first one brought into the states from Japan way back when! This is his unit! It does have a low serial number! (13212) This DX7 was modded with a knob to switch to four banks! Also includes a Data Cartridge filled with more sounds! Pick new bank press a preset and you are playing a new sound!

All sounds play great and the sound cartridge has custom sounds. Only functional issue is two keys are down, but return springs are not missing. These two are not staying latched.”
