trunk rev 5562
- mac lion 10.7.3, xcode 4.3, compile rev 5562 and debug, mainly using soundfont : GeneralUser GS 1.43 MuseScore.sf2, acoustic_piano_imis_1.sf2
- open a music score, play it, the audio is distorting
- If in both Mixer & Synthesizer dialogs, set chorus & reverb effects to 0, then the audio back to normal.

I think maybe you have the reverb return too high.

Leastways that is how I got round this problem several releases ago.

The problem being that the reverb built up a feedback loop which ended up overloading the sound system.

This is set in the synth window - if you are seeing the volume bar in that dialogue red-lining then reduce the reverb level in that dialogue.

Also adjusting the damp and room size controls affect this.

Maybe my problem is caused by AEOLUS, because when I set AEOLUS = FALSE in main CMakeLists.txt and compile again, this problem disappear.
