As I tune in Eb, I tried to export the tracks so I could transpose them a half step down but no luck, it seems that Jammit is protected against that. I tried using the "what you hear" functionality to record the sound in real time, and even video capture it to make a demo, but as soon as I press record on any other soft, Jammit stops playing. Anyone has a solution for that ?
Adobe Audition does that for me as well. Your software is releasing whatever driver it's using, I think.
However, AUDACITY does not do that... it records just fine on my laptop.
