I found another PocketPC Drum Machine. This one has a bit of a twist. Here’s the product’s details:

Drum Kit Ace is a brilliant music & memory game and also an easy to program drum machine!

In the two game modes Memory Master and Rhythm Master use your touch screen stylus to hit the drums and follow the computers lead. Practice drumming in Freestyle mode, complete with metronome to help improve your timing.

The Drum Machine enables you to create up to 99 drum tracks. The interface is simple and intuitive. If you play an instrument (e.g. guitar, bass, keyboard) then why not create a drum track to play along to…for fun, for practice, for real.
