Up for sale is an Alesis QS7 synthesizer in fair to good, used condition! It features 64-polyphony voices, 76 velocity sensitive, semi-weighted keys, on-board effects based on the famed Alesis QuadraVerb 2 processor, 512 presets and both expandable ROM/RAM and preset memory. It's in used condition with a few repaired keys and two keys that feature chips along the front, that shouldn't affect playability. Two keys near the chipped key feel different when depressed and might need work to have the same semi-weighted feel as the others. Other than a few dead pixel lines on the LCD, everything else works perfectly and it sounds nothing short of incredible!
