Cakewalk makes three additional stereo inputs available to SPAN giving you a total of four. I think some of the videos talk about that. I don't think the one suggested above talks about using multiple inputs. I usually put span in a Group or Mix bus. Once SPAN is loaded in the bus, I go to up to three of the tracks feeding the Group or Mix bus and assign sends to the additional three inputs allowing me to analyze all four track spectrums and overlay one over another. Only two spectrum graphs can be displayed at a time.

Exactly. The first SEND/TRACK must go alone to the BUS running SPAN. Other 3 kind of goes like a Sidechain SEND, and are named SPAN Input 1 that actually will work as MID/SIDE comparison and is, in fact, the second SPAN input. I just don't recall how to set the first step of the whole process... Thanks!

I know you gonna laugh at me but the thing is that months ago when I started learning C♭B, previous REAPER trial period, I actually managed to have 2 tracks, and their own freq. spectrums, analyzed in real time in a single Span window. Span was running in a exclusive BUS, just beside the MASTER BUS... I'm not gonna rely on my memory but that was sort of a SEND and/or PLUGIN PROPERTY setting, can't recall, anyway... Tomorrow is my day off and I gonna try to accomplish it again.

Thank you guys! The basic setup for monitoring a single signal is a very useful technique... I'm stucked at the how to set Span/C♭B so I can see the freq. spectrum of >1 track in a single Span instance. 

If you can help I´d appreciate
