MidiPatterns is a multitrack, pattern-oriented, MIDI step sequencer. You can use it as a simple drum machine, or to handle complex multi-timbral, polyphonic scores, controlling multiple hardware and software synthesizers at once. Please note that MidiPatterns does not generate sounds by itself. Features: ? virtually unlimited number of polyphonic midi tracks per document ? output to multiple MIDI devices, directly connected or linked through a network ? virtually unlimited number of patterns per document, each with a size variable between 1 and 256 steps and specific time signature settings ? each step in a track can send volume plus 8 midi controller messages ? randomizing capabilities to improve expressiveness: notes properties (velocity, duration, probability, swing) and step controller messages can be set to change subtly and randomly during playback ? patterns can be assembled in variable length sequences ? imports and exports MIDI files ? MIDI clock synchronization, both as master and as slave ? articulated mute and solo configuration
