Thanks for this, it works!

As a fallback, I wonder if this is safe:
1) stop the dls unit's graph
2) AUUninitialize() the dls unit
3) AUInitialize() the dls unit
4) start the graph

I haven't tested it yet. I would expect this to
work as far as resetting the GM synth, but is it
safe from the way the graph references the unit?

That is certainly an option, and I'd imagine we'd keep this around, but its not something I'd like to guarantee....

So, as long as you check that the file exists, and have a "fall back" plan, that should be OK - we wouldn't arbitrarily change the name or location of this file.

This suggestion may be too lame, and haven't tried to see if it would work...

If we can "count on the location", perhaps could attempt to set the kMusicDeviceProperty_SoundBankFSSpec property to point to--

System:Library:Components:CoreAudio.component:Contents:Resources:gs_in struments.dls

We've not really provided a way to do this - ummm... if you really need to, the best approach is to make a fresh version of the DLSMusicDevice unit and swap it in for your exsiting one...

After using a SoundFont or DLS file with a MusicDevice
(via kMusicDeviceProperty_SoundBankFSSpec), how does
one clear the sound bank and return to GM sounds?

AudioUnitReset() doesn't do it, and setting the property to
nil returns an error -50.

Thanks for help,
