On my system it sounds OK at 32 frames and 128 frames, but crackles terribly (no xruns though) at 64. In any case it crashes within a minute. Also, there is a known issue where starting a new jack client causes xruns. I don't remember what the status is. My theory is that the VP patches are exposing bugs in other apps. Lee
