Thanks for all the help everyone... it is MUCH appreciated.
Marc: It is showing up correctly in the profiler, so it looks like USB connectivity is probably not the issue.
Chicago: I did not load up the template file (for some reason I couldn't find it when I tried to... probably because I'm a dumbass
) But I did check and have the setting you mentioned in place.
Plus using buffer size of 256, etc...
So I have had issues (differentiating in severness) on 3 different machines.
1. New Mac Pro
2. Maxed out Macbook Pro 4 GB that is the second to latest generation
3. 3 year old Athlon PC
I also tested this a few months ago on my buddies 17" macbook pro with no issues. But if it is "synth related" then something could have happened since then.
But this is interesting... I disabled my MAudio ProjectMix I/O Audio Interface AND mixer and was able to do a "good run" with no screw ups.
Problem is the "loud pitch stuck note" bug is extremely random and I've had good runs before.
...But I tried HARD to tweak it out (by hitting a ton of keys while chaning settings) and it worked like a charm.
So I'm now trying the projectmix I/O without the interface control to see if that works. Will update here when I figure this sucker out
