How about adding 3-band/3-color frequency characterization? Scale-able size and the spectrum characterization would be very helpful to isolate phrases, especially during long/sparse breakdowns.
Recommendation - Rekordbox Waveform Colour Change & Increase Height Size
Any chance of brightening up the Rekordbox Waveform Display from Grey to something brighter (Green?) so it makes things a little bit easier to zoom in to cue up/loop unquantized areas?
Also increase waveform height size maybe? Would be good to have a drag up/down bar to increase/decrease this. Its quite small on the screen. Does it need to be that small?
Just a thought.
I would like you also could see it in spectrum mode like in rekordbox software or in traktor or serato, I think CDJ 2000 Nexus is enough for doing it.
