“Auction for a Yamaha DX100 FM Synthesizer. Some minor cosmetic flaws, but is fully functional to my knowledge (tested, powers on, makes sound, all presets are functional, pitch controller, oscillator wheel, volume slider, etc. all working). Not skilled enough to have tried to make my own patches.
Needs a minor repair: power in jack is loose and will cut out if the unit is bumped or moved. To my knowledge, the battery power function works, but it has not been tested (compartment is clean).” Click here to search for synths on eBay
