- Send the signal through a low-pass filter to one channel for processing the low frequencies
- Send the signal through a high-pass filter to another channel for processing the high frequencies
- To a third channel send the full range signal and also send the high- and low-passed signals but invert them so you end up with only the mid frequencies
I got this idea from a fantastic Dan Worrall video in which he uses linear phase filters although even if you use any other type of EQ this still works and will null with the original signal.

What you see is EQ8 Live (no oversampling) with a 48db four band split. SPAN and Bertom EQ Curve Analyzer used.

I'm extremely skeptical that a 48db four band split would perfectly null. No crossover filter I've tested comes remotely close to this from linear phase to minimum phase.
Only thing remotely similar when using ISOL8, where if the multichannel mode or mute/solo band buttons wasn't engaged it didn't actually start the crossover filter. Thought it was perfectly transparent before that.
Yes it works. No idea why it's not there as a plugin. What Autobot describes is also explained here in 2015 : http://blog.dubspot.com/ableton-live-tu ... ion-racks/
Did not made any testing so can't say how *clean* the splitting process is.
