Image Line (makers of Fruity Loops) are a bunch of smart cookies. I lay down part of a track I'm starting to like (with the beats in Ableton Live and the synths in Fruity Loops, which I just this morning figured out how to use as a ReWire device) - and I discover I'm using a synth instrument I have to pay for. Which I haven't bought yet. And when I saved it, it deleted the melodic line I'd just laid down. It warned me that it would do so, but I guess I just didn't really pay attention.
Augh!
Augh!
