I noticed a strange behaviour in Garritan, that I cannot solve and maybe some of you have already experienced this before and is able to ellucidate me. When playing one particular MIDI file (only that one) the volume slider of the close mic (but not the ambient) moves rapidly up and down with each note (!!!!!). So, the overall sound is like a very fast wah-wah effect. At first I did not even realized what was happening, and thought it was a buffer problem and changed buffer size, then changed driver, then reinstalled ASIO, and then saw the slider moving erratically on Garritan (I was rendering on Reaper, so the garritan window was not open). The same midi file plays perfectly on all other VSTs (VSL, pianoteq, Noire...) and I don't see anything strange in the midi events of that file (it has "key pressure" events because it is an XP MIDI file, but even If I delete those, the file still causes the same up and down movement of the slider).
Anyone saw this before? Is something related to Aria?
