The third edition of PSPSeq, a fully-featured homebrew sequencer app with 16 audio tracks, is now available. You can use your own samples (in WAV format) or use a selection of softsynths to put together your choons. Hack a Day interviewed creator Ethan Bordeaux, who says the inspiration came from an attempt to write procedural music:
myself and some friends designed custom DSP hardware to create autonomous generative music (the project was called Chiclet). I created the synthesis engine running on the DSP. I learned a lot from the project but wanted to make a tool that could contain some of my synthesis and sequencing ideas but in a more user friendly package ... I also considered using the GP2X however the PSP has a lot more horsepower and a larger installed base.
Listen to Keira, a track made on the new edition. Anyone out there remember the days of MED on the Commodore Amiga?
