i was trying Scott's transformer match tip earlier. All of a sudden, no sound, patch amps have reverted to 59 bassguy, vol, pitch and other fx blocks missing from layout. i have a gig tomorrow - NOT GOOD!!! I tried to reset sys params, i tried rebooting while holding down recall. I tried reinstalling firmware, downgrading to 5.7, restoring user bank A from onboard rom. Nothing. Help please...
