interesting product...

but you can already do this in Real Band. If you hum along with your song and record it in a mono track, you can convert it to MIDI and apply patches to it, all without leaving the RB environment.

You can also export your hummed track to melodyne and make the same conversion there, then import the MIDI back into the project. But, that takes more steps.

If nothing else, this video has made me more interested in spending more time experimenting with RBs audio to MIDI feature.
