midiGATEs midi probability is an Audio Unit v3 MIDI Effect and CoreMIDI capable app. midiGATEs listens to MIDI input and based on random chance mutes some of the incoming notes to make a busy, repetitive stream of notes a little more interesting and sparser. 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, normally not used but there if you need it. If midiGATEs is inserted as an AUv3 MIDI effect in a supported host such as Audiobus or AUM it should setup and work automatically. If you wish to use it without an Audio Unit host you can toggle the CoreMIDI input and output and use it that way.
