SimplePercussion

SimplePercussion has all 47 standard MIDI percussion instruments, which can play together in a loop of up to 70 beats (depending on your screen resolution). Just Mark the boxes corresponding to the instrument(s) and the Beat, and then play it. A moving vertical line shows the beat being played. Save to/open a file, change beats/second, beats/loop, and beats/heavy vertical accent lines.Also works nicely as a simple metronome.
