I am a DJ / electronic musician who works with current dance music / remix projects. What is in VoiceOne / VoicePro for me?
You could make your vocals sound more professional using pitch correction or by throwing in the odd harmony or a little vibrato. Or you could go the other way; re-synthesize, de-naturalize, and robotize your vocals to fit your mix.
VoiceOne / VoicePro gives you the tools to 'go clean', or to 'go experimental' as you see fit.
