Working with real-time MIDI

While ARIA is useful for playing MIDI files on a 3DO Station, you will find it even more helpful for editing MIDI files in real-time. Since the actual process of editing the MIDI files depends on the sequencer you have available, this section only gives a brief overview of the process:

Connect the Output of the MIDI sequencer to the Input of ARIA, using the Apple MIDI Manager's PatchBay application.
Load the MIDI file you want to edit into the MIDI sequencer (or start composing a new document).
Make sure a MIDI project document is the topmost document in ARIA.
Make sure there is a PIMap in the MIDI project window and that the PIMap is loaded into 3DO memory (see Playing a MIDI file on the 3DO Station.)
You do not need to attach a MIDI file to the MIDI project document; MIDI is interpreted in real-time from the sequencer or keyboard.

Note: Running real-time MIDI is more reliable if the MIDI Manager Patchbay application is up and running before any of the other programs are launched.
