I've just had my first red lights of death after about six months with the unit. Still running firmware 1.10 but will do an upgrade later. I didn't have any problems until I changed a patch (originally 01B Lead the Way), which had been running fine all that time with some minor modifications, to use smart harmony instead of whichever mod pedal was in it to begin with. I also moved it to the end of the signal chain (well, before reverb) as it sounded crappy before the amp. Now the patch will sometime work for a while but sometimes will freeze whenever I try to change away from it.
Has anybody seen a resolution for this yet? I need the harmoniser!
