Multi-track Realtime Spectrum Analyzer in Studio One 3

Some recent live recordings have had (sonic) drop outs of either bass guitar or kick drum depending on which was dominate at the time. Some plug-in research has given me reviews of multi-track spectrum analyzers - but they usually have no (real time) affect on the track parameters just the ability to see what's happening in real time. The Pro-EQ looks like a good candidate. Perhaps putting together a multi-track analyzer layered so the signals can be altered in real time would be an interesting plug-in and very valuable.
