Hi David,
Just took a listen to some of the demo files and WOW that's impressive

Not just the AI vocals (thanks for the tip on ACE Studio), but the entire production (or at least as much as I've listened to) would be a definite blast to put on. I sure hope you can get someone to nab it and put it out there. Wish I had a theater group now. Or was independently wealthy....
Best of luck - I would love to see this on stage
ttfn,
Sherry
p.s. In reviewing the Ace website, they list "Turn vocals into MIDI & lyrics & pitch by acapella convertor". I'm guessing that you used the "turn lyrics and MIDI into vocals", but I'm quite curious now about how well the vocals->MIDI works. All previous audio->MIDI progs that I've tested have been pretty abysmal. Have you tried this particular feature in Ace?
