The only way that i know of is to use the channel tools plug in to reverse the phase. I have done this with effects and it works well. There is not anything built in the bus that allows you to do this. But channel tools works great for this.

That's what I resorted to also, but there's a bit of delay added so you don't get complete cancellation.

Currently looking at the Blue Cat plugins, most of the analyzing vsts they have can send automation CC's based on peaks so that might be a better solution to automate things like EQ in realtime.

Try this

Kenneth,


Yes given your example I can see that, and I can see the need for a lower latency solution. When I used phase reversal it was with two buses that had identical stereo effects and parameters, I sent two identical signals reversing the phase on one of the buses would cancel both effects with no loss of latency or delay. Then adjusting some of the parameters in one of effects on one of the buses caused only the tail end of the effect to be heard. Great studio trick, but your example calls for a lower latency solution. Let me know what you find. I also looked at those blue cat plug-ins

I'm still contemplating which one of the blue cat plugins to buy, I'm thinking the "Digital Peak Meter Pro" is probably the one having the lowest added latency.

I just discovered the phase trick with purchased stereo drum loops.
 
i was struggling with standard EQing, until i tried the "carving" technique with 2 tracks out of phase.
 
FANTASTIC! my drums POP now.
 
only issue is organization.
 
i usually have a track for grooves and another for fills.
 
with the phase EQ trick, i need a pair for each spectrum carve. basically kick, snare/tom and overheads.
 
that's 12 tracks.
 
i had the BRILLIANT idea to have 2 tracks (grooves and fills) AUX sending to 3 pairs of busses.
 
but alas, no phase button on the bus. makes sense though, you need wave data to invert.
 
looks like some options out there though...
 
... AAAND this little guy recommended by Bristol_Jonesey worked like a charm on the BUS

it's bare bones, and has a LITTLE sonic residue - but workable:
 


 
there may be other, better plugins for this, but this gives me hope AND keeps my track count down.
 
i'd rather bus than track.
 
nice stuff!
 
this phase "carving" trick is the friggin' POOP!!!
 
it's kinda like an ALPHA MASK in Photoshop.
 
damn, my nipples are hard with this stuff.
 
 

If I understand the aim of this routing correctly, couldn't you achieve the same thing by side chaining one band of a multiband compressor? 

If I were looking to invert phase on a bus I would use Channel Tools or use an Aux track instead of a bus. I would avoid 32bit plug-ins where possible.

Yes that was my second thought - use an aux track, it does almost entirely the same thing as a bus track and may even be more elegant since you can keep it next to your source track. 

i briefly looked at the Sonitus fx:phase plugin.
 
not sure if this will work for my purposes. will try after work.
