PatternSequencer
![]()
simple MIDI pattern/step sequencer
PatternSequencer features up to 16 parts, each of which can have 8 different patterns. You can set MIDI channel, volume, bank and program number for each part. Patterns can be up to 128 steps long. Timing can be 4, 8 or 16 steps per beat.
Notes are edited on a 32×16 matrix. A note can span multiple steps by dragging the mouse.
Patterns can be looped or arranged as a song. This is done in the “Score Window” where you can specify which patterns should be played in a certain sequence.
It requires Mac OS X 10.3 and some kind of MIDI synthesizer. If you don’t have MIDI hardware, you can use a software synthesizer like Pete Yandell’s excellent SimpleSynth (459 clicks).
