QS7 was developed by Alesis., Released in 1996
The QS7 was released shortly after the QS6 as an enhanced and more Studio-quality version of what was already a powerful multitimbral synthesizer from the effects-box geniuses at Alesis. It featured a larger 76-note keyboard with semi-weighted action and a more conservative black chassis. Additionally, the sound engine has been doubled from 8 to 16 MegaBytes of sample/synthesis ROM (and is expandable to 32 MegaBytes). It also added 2 more stereo outputs, 2 more assignable control sliders, discrete MIDI OUT and THRU ports, a third Expression Pedal input, ADAT optical digital output, 48kHz clock input, and a second PCMCIA expansion card slot.
