I’m developing a script in Python that captures the notes of any song in Virtual DJ and sends them to [Waves Tune](https://www.waves.com/plugins/waves-tune) Real Time. I’ve managed to set the scale in some cases, but the notes don’t respond coherently. If I use learn mode, sometimes it shows CC20 for ROOT and Scale, and sometimes it shows CC21. I haven’t found any information indicating how to set the musical notes. I think that since the plugin offers this option, the information should be easily accessible.

This is an interesting idea. Hopefully someone from Waves can chime in here.
