Here are two long and slow drum-free tracks I wrote where all the parts are in different time signatures. The sequences essentially all loop (with lots of live parameter tweaking etc) but at different lengths. In some cases two (MIDI) sequences are going to the same instrument, for example the plucked sound that goes on far too long at the start of the first one.
I don't think these tracks are amazing or anything, but I enjoyed making them and hope they're of interest. They worked well in a live setting. I hope this isn't perceived as too spammy.
Here's another one, Hoops, that is more of a pretty electronic pop thing - more like an old Plaid tune or something - with drums and what have you. Rather than being polymetric it's what I think you call a compound rhythm - a four bar phrase but the bars are different lengths. To my ears it does just feel quite pop still, which I was pleased about.
Edit: the first thing I ever released was in 11/8 now I think of it.
