Special handling of GM, GS, and XG MIDI files
General MIDI compatibility of a song file is indicated by the presence of a special System Exclusive message at the beginning of the song. When Music Creator finds a GM, GS or XG reset message, it assumes that you would like to work within the GM Score Production guidelines. This causes Music Creator to use special timing for program change information when writing MIDI Files, and allows it to search more aggressively for track parameters when reading MIDI files. The result is that it is easier than ever to create and use General MIDI song files with Music Creator.
Music Creator does not enforce or even verify compliance with the GM guidelines for your music data. But Music Creator does comply with them when generating events that represent track parameters. If necessary, Music Creator will insert blank setup measures at the start of your song. This makes space for certain events to be inserted at the correct times at the start of each track: bank changes, patch changes, volume, and pan. This means that you can use Music Creator’s track parameters for these settings when composing songs: When you save your work as a MIDI File, Music Creator will place these events in the track at the specific clock ticks recommended by the guidelines.
You can tell Music Creator to follow the GM guidelines by loading the “Turn GM System On” Sysx bank in the Sysx View (gmsystem.syx in your Cakewalk directory), and then either inserting a sysx event at time 1:1:0 or using the Auto setting for that bank.
When loading a GM file, each track’s bank, patch, volume and pan parameters are lifted from the data stream and placed in Music Creator’s Track view for you to see and edit on-screen. The GM mode ensures that all patches, banks and controllers are placed at specified times throughout a setup measure when you save a MIDI file. This ensures that all setup information can be digested by your synthesizer before it starts playback. If you don't have a setup measure in your project, Music Creator will insert one for you.
If there is no GM, GS, or XG reset System Exclusive message present at the start of your project, Music Creator  will not operate in this GM mode.
