I play with Soundtracker. Stuff comes out.
- Men of Focus - Von Hat (Joe H / Sigur Ros)
- Men of Focus - Whipsmart Twist (via Whipsmart Ice)
Or, more recently, GarageBand.
(Find out where the name comes from.)
People I (vaguely) know do similar things, only much, much better:
- Joe Holmberg: Krauschanl and Ropebridge
- Rupert Lally
- Phil Jones: Gbloink!
- Salter Cane
