Samplitude seems to be the only DAW that uses Comparasonics waveform coloring.
You can spot frequencies based on the color which is really useful for audio editing. Plus you can search for similar sounds using comparsonics waveform search.
But I noticed that Craig Anderton is a fan of them as he mentions them in this article :
Maybe his influence could mean they will appear on Sonar one day?
