It would be great to be able to have separated channel analysis for certain modules ie:
Kick Drum
Snare
Bass
Piano
Vocal
Could show up as different colours
Spectrum Bar, Spectrogram, Multipanorama, and many more could all be capable of featuring this.
Even Balance could have multiple differently coloured nodes (might want to make the football a hollow line when this mode is activated to be able to see overlap, in fact some of other modules like Spectrum Bar would need hollowed out graph elements when multi-channel enabled)
I would love to have my template group buses setup and ready to go with these features.
