In essense, the QD is a 4-voice digital drum module in 22hp with internal mute and panning plus some very flexible CV assignment. Each voice can be a sample player, a wavetable VCO or a digital drum model, so drums are really only one possibility. Maybe “Quad Voice” may have been a better name, but drums are the focus and just because it can do other stuff doesn’t mean we should lose sight of the maker’s intentions. For each voice you have control over pitch, decay and sample selection.
A little SD card slot on the front can hold 1024 samples loading 128 samples into each voice at a time which can be selected via CV. The included digital drum models offer a range of kicks, snares, hats, strings and other percussive sounds.
