This MIDI device is used to split a MIDI chord dynamically.
If you play a chord on your MIDI keyboard, it will pass for example only 2 lowest notes of the chord, or the 3 highest ones.
If you use it on two different MIDI tracks sharing the same MIDI input, you can dynamically split your keyboard and control two virtual instruments with one chord voicing.
