I only use the TI in standalone mode. All of this is occurring directly interacting with my TI Key.
I reverted to an older OS and it's more stable as far as digital glitches and lockups at the moment, but still have some stuck notes.
I am still having trouble with the arpeggiator in multimode. I may be doing something wrong, but while I just programmed some multis with the arp, I all of a sudden can't save any multis with an arp turned on. What am I doing wrong? I can't even save a multi that I've saved with an arp in Multi #14 to Multi #18 either. The store button does nothing, but I can save a non-arped Multi to another location. I may not have known of this restriction, as I've never encountered it before. I'll RTFM.
