This free Max for Live device delays the release of MIDI notes for certain amount of time. Control the amount of release time with the “Release” dial. Clear notes held by the device with the “Clear” button.
Useful for adding release to MIDI instruments that don't have release. I made this because I've been modulating a lot of MPE recently (new MPE devices incoming), and MPE modulations stop when the note is released leading to a sudden change in the sound.
