Yeah that app needs work like quantization both for rythm and scales and so on. It could be a really powerfull tool I think.

Make a webapp at least, allow me to export some useful format for logic.

Then you can work on other ways to use the voice to inform the sounds and other things. As I said. Think about it like VocoderMidi instrument/sequenzer. Something really useful can come out of that IMO.
