Default [4.731] Apple DLSMusicDevice crashes Reaper

I haven't used Apple's DLSMusicDevice plug-in in REAPER for a long time, and I don't remember encountering any problems with it the last time that I did. While playing with it today, though, I found that it crashes REAPER without fail as soon as I close the FX window. Here are the steps to reproduce the problem (after REAPER is already open):
  • Click the FX button on a track
  • If on a track that already has FX, click the "Add" button to open the FX browser
  • Choose "AUi: Apple: DLSMusicDevice" from the list and click OK
  • Close the FX window
  • REAPER instantly crashes

System details
Mac OS X 10.8.5
Mid-2009 MacBook Pro
REAPER 4.731/i386 87a685
NOTE: The same crash also happens in 4.731/64

hi jsbarrett, and welcome to the forum!
it looks like a known issue in Lion (i.e. DLSMusicDevice crashes other DAWs as well -- in 10.8), it has been fixed in 10.9.

Thanks, Jeffos. I've been hesitant to move past Lion in part because I haven't looked that deeply into how well Mavericks (and now Yosemite) will play with the software I use, especially Reaper. I suppose if I plan on using the DLSMusicDevice, I gotta make the jump. Research time!

DLS in Reaper always has worked fine for me under Mavericks and now also no problems under Yosemite.

Default unfixed

Doesn't work for me under El Cap. Initially it did nothing but present Quicktime Music Synthesizer greyed out, and no sound. Once I downloaded a soundfont, QMS and the soundfont both became selectable, but it only plays 4 or 5 notes and quits. When I hit stop on the transport bar, the rest of the notes play at once. OSX 10.11.6 and Reaper 5.22 32bit.

I haven 't got a clue about DLSMusicDevice, but why are you running a 32 bit Reaper on an OS that has been 64 bit for ages?
