Hi, is it possible to change tuning of guitar in real time using native instruments guitar rig? For example, want to learn song that is down a half step. I want to plug into guitar rig and tell it half step down and off I go. So, this needs to be in real-time. It doesn't look like guitar rig could do this, maybe not possible for processing reasons. Any other programs out there? I understand that it probably is not possible to alter string tuning, but to drop the whole thing down a half step equally seems possible. thanks, Sean Also, why is the volume pot on guitar amplified ten times when adjusting. It's so scratchy and I don't hear this at all when I plug into an amp. The scratchy sound is louder than when playing.
