I've tried loading up 4 different soundfonts in the DLSMusicDevice, and each time, it crashes GarageBand as soon as I close the DLS window and return to GB's main window. It's a new project with just the 1 instrument track. It's my first experience with soundfonts in
GB and its not going very well so far.
Anything I can try? Is there a better soundfont player plugin for use in GB?
It may be Mt. Lion. There have been other reports:
See for example: Soundfonts making GarageBand crash
I tried your soundfont on my Snowleopard installation (Mac OS X 10.6.8 with GB'11) and it works great.
But on Mt. Lion it crashes most of the time, if I use any soundfont.
More soundfonts are here, see the FAQ: http://www.bulletsandbones.com/GB/PlugInsSoundFonts.html
I have not used them since I switched to Mt. Lion. For me the additional instruments in the JamPacks that come with MainStage 2 are sufficent. They work very well with GarageBand '11 in Mt. Lion.
