1) In the beginning there was sound, so load some percussion samples.
2) Next we need to set up the machines. Add a Groove 1 (optional), a BTDSys peerctrl and a BTDSys stutter (both required). Connect the looper to the master (or route it through other fx).
3) Time to get some weirdness going. Set the Groove 1 to 48 swing. Then, for each track in the stutter (I prefer not to use more than 3 tracks because more just creates cacophony), create an assignment in the peerctrl and link it to '[T] 6: Loop Time' Set slightly different value mappings for each assignment/track, but keep them very very close to the bottom of the drawing area.
4) Ok, we have it all set up, so it's time to edit the stutter patterns. Bring up the pattern editor and enter some 1's and 0's where you want them on some or all tracks. I find it works best when you enter a 0 (off) immediately after each 1 (on) - it keeps the loop neater. When you're done, create a pattern for the Groove 1 and add a 1 in the trigger field.
5) Move to the sequencer and add your sequence(s) for the Stutter and the Groove 1. I usually just paste the Groove 1 pattern all the way down to the end of the song, so when I click elsewhere in the song to play from there, the Groove doesn't trip.
6) Prepare to boogy! Press play!
Tip: If you're not satisfied with the loop you've created, tweak the value mappings in the peerctrl.
