Hi there,
I have the same annoying problem with ghost notes, mostly when the room temperature rises above 23 C .. I want to use the TI2 Polar in my live setup (also as audio interface) but it is almost useless when it alsways triggers some notes and one has to push the panic buttons to stop that. Had that problem during my last gig for several times and it almost ruined that track..
An other problem is that the TI2 sometimes seems to loose the internal Clock-Lock, the Delay Effect then gets some weird up-pitching-effect for 1 or 2 seconds before it locks back to the tempo :-/
Maybe it is a way better idea to sell that crappy TI and buy another rock solid Nord Lead.. Never had any problems with any of my Nords.
