I just tried to compile the Juce demo plugin r726 under OSX, and it appears to conflict with the keys in Digital Performer.
At first once instantiated/inserted the keys are passing thru to DP (i.e. spacebar & the like for play/stop/rewind …)
But if you close the JuceDemoPlugin, then reopen it’s GUI, now the keys are not passing anymore to the host but generate osx alert sound.
The problem doesn’t happen with tag 1.46.
Anyone else ?
