I'm having problems with Stringport. After a short while the sound degrades to a very distorted sound. The only way around this is to reset the I/O vector size in the audio setup settings. This repeats after less than a minute of playing. I have tried quite a few things to remedy the problem with no success.
I filled out a support ticket a while back and have not heard back. Anyone have any ideas? I am using the latest version for violin(1703) on a new macbook with the latest Mac OS.
