Vad1er - pretty much nothing works at home with that software but my FP10 by Presonus. At least I have one I can record in the collaborations with.
I did have a PreSonus Firestudio Tube for a review by the manufacturer and RW really mangled up the driver on that one, had to reinstall, but that is back traveling toward Presonus. I am not sure on who to blame the issues though cause compared to the FP10 the driver didn't "feel" as solid. Just intuition, you know

I am really surprised why this software can't work with a simple USB interface on a Mac - after all it is just an USB driver that for shows up in all audio applications already. Maybe I need to uninstall RW and find any and all files that could be on the hard drive, delete these and then reinstall. Or just downgrade back to the version that worked???
On another note Vad1er - I sent you a PM if you can describe how to record the length of a whole song.
