nanodot is a rather minimal pattern-based MIDI sequencer for BeOS R3. Its main purpose in life was/is to teach me (and hopefully others) the basics of writing MIDI apps for BeOS; it also makes for a nice drum-programming 'scratchpad', and is a generally entertaining way to waste a few hours.

It features (surprisingly) tight MIDI timing Four 16-step patterns per window; multiple copies of nanodot may run concurrently for as many patterns as you like (at different tempos, too, if you feel like juggling beats...) Fine tempo control (with easy keyboard adjustment via the left/right arrows; click on or beneath the slider to give it the keyboard focus).Mute button.
