Yeah - used to do it a lot, you come out sounding like hardfloor, it's cool. 3/4's of a bar is an easy win for an acid line or 7/8ths. surely you just repeat the part but actually loop the tune on 8 or 16 bars, if you've got a complicated thing going on then wack a little fill in at the end of the 16th bar to pad out the gap so you can start on the first note again otherwise it'll end up like free jazz or something.

half of the high energy trance riffs you hear have their emphasis on 3/16ths 'cause it just sounds so damn exciting.
