MIDI Channel Phase Mixer v1.0
From a design by AudioBus Forum member @horsetrainer

When the script receives a Note-On message it will be sent out on the channels specified in the top row of knobs after the delay set by the knob below it. If the top knob is set to Bypass no note is sent regardless of the delay setting.

When the script receives a Note-Off message it is sent immediately for that note on any channel on which it is playing, and any queued Note-On messages for it will be cancelled.

Sensitivity: reduces the maximum delay, making the delay knobs more accurate.
Accuracy: Higher settings mean less CPU work at the cost of timing accuracy. Increase this if notes are sticking or not playing as they should, or the script is spiking CPU. Otherwise it should be left alone.
