My GP has worked perfectly ever since I bought my license V4 and the upgrade V5. But suddenly the output signal mutes for about 1 second every 19th second. Almost as if it is working in some demo mode. The problem happens no matter rackspace I use.
I use MacBook PRO M1 with XSonic Xtone Pro (USB-C to USB-B)
Can you please remember what changed before this issue started to happen?
Operating system update, driver update?
Can you do a test: open your gig file and in audio options select your internal audio chip. Does the problem happen this way?
Do you use a USB hub?
