Maintaining stereo separation?

[Deadpool_25]

My FM9 signal chain runs through parallel amp blocks with each amp hard panned. The amp blocks are set to mute on bypass. The amp blocks converge into a single reverb block and then go to output 1. Output 1 feeds two real amps’ FX loops/cabs.

When I mute an amp I still get the reverb through both cabs. Is there a way to keep the left/right input/output isolated through a single reverb block? So if I send it only a left input, it only outputs on the left side?

I know I can use two reverb blocks—just curious if you can do this with one.

Probably a dumb question, but do you use 2 IR slots in the cab block with the slots panned hard left and right accordingly?

As a general rule, effects which produce stereo, like a reverb, sum the 2 inputs before processing them. If you want two independent paths to feed two cabs without any summing, you'll need to use 2 reverb blocks.

You could also use a scene controller or change the channel on a single reverb block so its output is balanced Left, Right, or Center as needed, or use output block channels -- this in addition to muting one of your amp blocks.

@bdrepko that's generally how it works but the pans don't necessarily need to be hard.

No cab block. I’m using real cabs.

Ok. I thought that might be the solution. Thankfully the FM9 will have no problem doing this without crushing the CPU.

Also an interesting solution. Hm. It’s really only an issue (and a minor one) when dialing in a tone so this seems like a pretty good idea. Adding a second reverb seems good too. I’ll play around with the two ideas. Thanks!
