RhythmPro lets you create and play your own custom drum patterns with real digitized drum sounds on a Palm handheld. Or it can also be used as a versatile and extremely accurate metronome. You can create rhythm patterns in almost any imaginable time signature, save and organize your patterns into categories, and play them using your choice of four different display modes for optimal visual and audio feedback. Set the tempo for each pattern using the onscreen controls or just tap the screen twice in time and RhythmPro calculates the tempo of your taps and begins playing.
