Step 1) Plug in your ERAE Touch into your computer, after you have turned it on.
Step 2) Open Bitwig, and in your file tab, select settings.
Step 3) Add two controllers, select Erae Touch MIDI on the first one, Erae Touch MIDI (MPE) for the second, this way you can use MPE and non MPE instruments at the same time.
Step 4) To enable MPE in Bitwig, just click on the VST you are currently using in your project and select the “Use MPE” button. Make sure you change the channel of the instrument track from “All” to “Same”.
