Great if you are working with MIDI.
MIDI Notes is very similar to a midi keyboard but with the advantage that you are able to configure all notes as you wish, and have multiple configurations ready to play.
MIDI Notes send send MIDI packages to different channels with a large range of notes and velocity (the force/volume of the note).
Please pay attention to the fact that MIDI notes does not play sounds. Youll need to interact with other MIDI apps.
