Of course. I'm just putting this out there so people know about it. It certainly opened up a whole new world to me. Controllermate supports multiple keyboards, you just gotta be sure you connect them in the same order every time. It also has 60+ 'building blocks' to choose from, including logic gates, making it incredibly intuitive and versatile. I just don't like being the only person I know pursuing jamtronica with Ableton and Controllermate.
Controllermate for mac can make any usb keyboard into a midi controller. It's incredibly versatile, very straightforwards, and costs about $20.
