From the developer:
MidiPatterns is a multitrack, pattern-oriented, MIDI step sequencer. It can be used as a simple drum machine, or to handle complex multi-timbral, polyphonic scores, controlling multiple software synthesizers and hardware expanders at once.
Supports multiple tracks: virtually up to 32000 polyphonic MIDI tracks per document, altough memory, MIDI system capabilities and your sanity will probably lower that limit.
