I have a studiologic TMK-37 midi controller and I can't figure out how to change the octaves that it triggers. I am using traction on a MAC. any help would be greatly appreciated.

The vast majority of StudioLogic controllers are Master Controllers, meaning that they only send MIDI on Channel 1. I have a SL 990-Pro from StudioLogic and use it with both Reason and Logic. If you need to have it send on another channel you might want to look into software routing the messages to another channel using MIDI Patchbay or a similar application.
