So far, I have had the TF crash (lock up) once while banking with a MIDI controller (Disaster Area). Second thing i noticed is that if you change the delay type on a preset and try to re-save it in its current position, is saves it with the generic delay type name.
Also, when banking into certain delays from other delays (presets) i encountered a loud squeal. I've had that happen before with my pedal, and changing some settings on the presets seems to help, but man is it alarming! Very loud and very high-pitched. Any ideas on what that is?
