midiFILTr-PG Probability Gate MIDI Filter Effect For iOS

Developer Arthur Kerns shared this video demo for midiFILTr-PG – a Probability Gate MIDI effect that’s designed for Audiobus 3, but also usable with CoreMIDI.

midiFILTr-PG listens to MIDI input and, based on random chance, mutes some of the incoming notes. This takes a repetitive stream of notes and makes it sparser and more varied.

It has four modes:

  • Gate Mode – One set percentage to be muted for all notes. Also includes Gate On Repeats (when a note passes through unmuted, also pass through X more notes after) and Gate Off Repeats (when a note does not pass through the gate, also mute the next X notes) to make things a little more interesting.
  • Note Mode – Each note in the scale (C, C#, D etc) has its own percentage chance to mute incoming notes.
  • Sequencer Mode – Every eight notes has a different percentage chance to be muted. Can also change the sequence length to be less than eight.
  • Thru Mode – Nothing is muted.

If midiFILTr-PG is inserted as an Audiobus 3 MIDI effect, it should be setup and work automatically. If you wish to use it without Audiobus you can toggle the CoreMIDI input and output and use it that way.
