This is more of a heads up, as I have a resolution (of sorts) to my issue.
Like many, I made the jump recently from F/W 2.92 to 3.00. I'm not normally an early adopter but recent firmware updates had gone well and so I deviced to have a leap of faith. The update itself went without hitch, but I soon ran into issues whilst using a 1SW Looper (the problem may also relate to the 6SW, etc., but I've not tested). As a relative newbie to playing guitar, my setup is incredibly simple, so nothing I'm doing is likely to be taxing the HX Effects unit too heavily. In fact, in this paticular case my setup simply included a Bass Octaver, Analog Flanger, Minotaur, Plate Reverb, LA Studio Compressor and a single switch looper (all on a single path).
My problem is that recording a 4 bar loop causes the HX effects to hang. I'm unable to end the loop and all switches and buttons cease to function; my only option being to power off the device.
I thought it may be an issue carried over from previous settings, so I performed a factory reset. Initially, I restored (only) my Presets, but as the problem persisted, I conducted a second factory reset and setup the pedals fresh. No difference, the unit still hangs.
I've managed to resolve my issue by reverting to 2.92 (which works perfectly), but this isn't ideal. I can't think what else to try at this stage and/or I'm not sure what additional information is needed to help troubleshoot.
Anyway, as I said, this is more of a heads up (for others who may be suffering the same issue).
If anyone has any ideas, I'm all ears. Also, I'm happy to provide additional information and/or conduct tests if it will prove beneficial.
