I've been really enjoying getting Ampire to work for me and getting some really good sounds out of it.
I'd like to see a noise gate and compressor integrated into the effects chain interface though, and more drive pedal options such as a Boss Superdrive, Fulltone OCD, Orbiter Fuzz, etc) and more reverb options such as hall, plate, room, etc. Not sure what it is now. Maybe even a stereo widener effect. Maybe there's already one in Studio One 4, I don't know.
That's it, thanks for listening!
Cheers!
