Milky is a tiny MIDI effect processor app that sits between a MIDI Controller and DAW software or another MIDI receiver. It can adjust keyboard sensitivity, invert the sustain pedal polarity, route messages to different channels, and more.

How does it work?
Typically MIDI Controller is connected directly to the DAW (Digital Audio Workstation):
[MIDI Controller] -> [DAW]

In case you need to change the output of the MIDI Controller (e.g., adjust velocity or transpose notes), Milky comes into the equation. All you need is to put Milky in between:
[MIDI Controller] -> [Milky] -> [DAW]

In this setup, notes come from your MIDI Controller into Milky. Milky adjusts the velocity or tone of these notes and outputs them. DAW software of your choice listens to 'Milky Output' and plays/records them. Alternatively, Milky can send the output directly to the Receiving MIDI device:
[MIDI Controller] -> [Milky] -> [Receiving Midi Device]

Easy setup:
- connect MIDI Controller and turn it on
- select that MIDI Controller in Milky
- select 'Milky Output' in your DAW**

- All Keys Sensitivity

**NOTE: Garageband does not allow MIDI input selection and, therefore, cannot work with Milky properly.
