MIDI access from sandbox on Lion

Hi,

We've got an app that uses MIDI which we're now running in a sandbox for sale on the Mac App Store. We use either QuickTime (OpenDefaultComponent(kNoteAllocatorComponentType...)), or DLS Synth (via AUGraph etc).

I notice that neither of these work in the sandbox on Lion, but they do work in Mavericks.

I'm not using any special sandbox permissions, but a bit of Googling suggests some temporary exceptions are required for MIDI to work.

https://developer.apple.com/library/mac/technotes/tn2312/_index.html

says

com.apple.midiserver

Required

com.apple.midiserver.io

Optional



Can anyone clarify what's required, and is the change between Lion and Mavericks as expected?


Thanks

Hamish
