i had this problem from the very beginning:
when i open vienna instruments or enseble in stand alone, after loading a patch and playing for some time, the volume suddenly drops and is about 1/4 of the original. nor controllers used - nothing.. and only restarting the program will help.. for a few minutes.
i am working on a macbook pro, 2gh core duo, 2gb ram with a m-audio firewire 410
anyone??
thanks in advance
