Comment 24 for bug 1074346

Would it be possible to change colour of the waveform dependant on key. I'm pretty sure there is a vamp plugin that can detect the key changes in music. I think it's the key detector on here - http://www.vamp-plugins.org/plugin-doc/qm-vamp-plugins.html#qm-tonalchange.

This could be really useful for detecting melodic changes and also finding where in the tracks to mix - i.e. sam colour should mixxx harmonically.

Thanks for the great work
Rob
