A full-fledged music sequencer for your Pocket PC? Impossible, right? Wrong! This app may be the single reason I abandon Palm OS in favor of Pocket PC. Construct and edit songs, create samples, mix tracks, and add standard effects, all from the palm of your hand. While editing music from a desktop environment is certainly more ergonomic, carrying your Pocket PC with you and building beats, or generating rough mixes when the muse strikes is a practical solution for creative types. Pricing for add-on instruments is a little steep, at approximately $17, but for the convenience of portability, nothing else is currently available.
