+ Connect up to 10 receiving apps (like synthesizers)
NOTE: This app requires Audiobus 3. Insert it into one or more MIDI input and output ports. Furthermore, this adapter only works with apps that allow you to select MIDI ports for sending and receiving. It won't work with apps that have no MIDI setup page.
IMPORTANT: Connecting apps via Core MIDI is an advanced topic. If you haven't done it before, please become familiar with it prior to downloading this app.
CONNECT YOUR "LEGACY" APPS TO AUDIOBUS 3
SETUP FOR SYNTH APPS (RECEIVERS)
For your second synth app, do the same steps, but select MIDI port "MF Adapter Out 2", and so on. Then, you can select it in the adapter app.
