Can anyone tell me what I can do with the sequencer on the Q. I mean a computer's seq can pretty much do anything so what purpose would the one on the Q serve?

It`s a step sequencer so quite useful as a "programmable" and transposable arpeggiator sort of thing, great for dance / Electronic music, it also sequences parameters such as cutoff etc. there are companies producing these type of things as standalones (such as Doepfer, Analog Systems etc) and are selling loads, so it`s nice to have one onboard..

Great on the Keyboard version or a non-racked Qrack anyway..
