I am using an application that sends a MIDI song selection message. From what I understand so far this is a “System Common Message” under the MIDI standard and is defined as F3 XX
11110011 0sssssss Song Select.The Song Select specifies which sequence or song is to be played.
If I open the global MIDI monitor in GP and send this message (for song 5) the monitor displays f3 05
If I attach a MIDI monitor to a MidiIn block in a rackspace it displays nothing. I thought it might be trivial to write a script to capture this and make a program change so GP would change it’s song selection but I don’t see any way to capture MIDI messages that don’t have a defined callback (ie Note/CC/PC)
There is a GetByte function but I can’t get the message to get to the bytes.
