Note Mirror & Multi Note Mirror
Note Mirror is a Max for Live device that will mirror incoming MIDI notes. If the incoming MIDI notes are going up, Note Mirror will duplicate that movement but going down and viceversa. You can transpose the mirrored voice, indicate the central note from which it will start to mirror and add a delay to it so it will start to play after a selected time. Multi Note Mirror is the same thing but with 3 simultaneous voices in addition to the original, useful to explore a different and experimental way of making chords and harmony.
This device is for Ableton Live.
