Never tried it, but this also should work. I have no glue but the distorted sound can have the following reasons: * Heavy system load * Old versions of JACK or even ALSA * Bugs in ams and/or om. At least Zyn behaves in a similar way when using it in conjunction with a hold pedal As soon as the distortion occurs, try restarting all applications, including jackd and check if the distortion reoccures immediately or after a certain period of time.
