I just got a new i7 system with 16 GB RAM (yay!) and installed Sonar X1, GPO and IO.
I feel sure this is user error but I get some kind of "can't find opcode" error when trying to use IO (I just realized I didn't even try GPO yet but I shut that machine down already and 30 minutes into my happy hour so....ummm ).
Anyway, everything seems to be relatively normal except modulation doesn't have any effect.
I thought I would post this to see if it raised a red flag for any kind of simple solution.
Thanks mi amigos,
