The output files look like QuickTime AIFF audio files, but when I play them in QuickTime Player they stop immediately. Whats going on?
The output files are indeed AIFF files, but they do not contain digital audio waveforms, they contain the MIDI data which only GarageBand knows how to extract. It is completely normal for them not to play a sound from a regular audio file player. • When I drop the files in GarageBand, they show up very short. Why is that? Go to the GarageBand -> Preferences dialog, click on Advanced and check that the “Convert to Real Instrument” preference next to “Adding Loops to Timeline:” is not checked. This prefence attempts to convert the output file from Dent du Midi into an audio format but fails due to the way Dent du Midi formats the converted tracks. • I tried to convert several files, but I’m left with an empty “-GB” folder, or files that GarageBand does not like. What can I do? First, try removing the preferences file “Dent du Midi.plist” in the Library -> Preferences folder under your home directory. Start Dent du Midi and make sure the “Pass through program change events” option is off,
