Cant help directly but do you have the attached DOD documentation? It might help..
Ref Page 20...

Yeah I was just reading through the manual actually, nothing.

Think I may have found my answer right this moment however. Looks like the pipeline plug-in can route it to external hardware. I wasn't doing that.

Will try that and keep my fingers crossed!
Thanks for that

The routing sounds really screwed up to me, but I don't work with one of those boxes.

It's about half mixer and half interface?

Draw your signal path out of paper maybe? works for me.

The way I would go about this is:

Set up an audio output to one of your line outs.

Then set the output of that trumpet track to the new output.

Run a cable from that output to your compressor.

Run a cable from the compressor to a line input.

Setup a input for where that compressor is plugged into.

Create a track and set the input to where your compressor is.

Done.

Just work with your levels and tweak it into shape.

You should not be using the sidechain inputs on your SR866. If you want to compress the trumpet, your insert SEND should go to the compressor's input, and the compressor's output should be routed to the insert RETURN (with a Y-Cable, usually).

You would use sidechain if (for example) you wanted the bass to turn down every time the trumpet played. The bass would go input/output and the trumpet would go to the sidechain input. Each time the trumpet triggered the compressor, it would turn down the bass.

I use my dbx 266xs compressor in S1 with next routing map:
Soundcard Focusrtie Scarlett 2i4 has 2 inputs and 4 outputs and mix monitor control which allows me to listen input and output.
1-2 outs to speakers.
3-4 outs to compressor's inputs then, from compressor outs to 1-2 inputs of soundcard.

I also have connection from Virus Ti outs to compressor's inputs - and jacks from iPad to Virus Ti to have recording ipad sounds through virus fxs and then compressor - sounds like geek trick)

In S1 you then choosing outs for track or bus. You actually have to go to Song options and set outputs and inputs before. I use compressor often on drums bus and send it out to 3-4 outs in s1 mixer.

Then you have 2 ways - if your soundcard supports input monitoring - you listen and tweak compressor the way you like and record on the new track with setting up inputs 1-2 as incoming signal. Otherwise, you can add audio track with same inputs and click "monitoring" and you will hear sound from compressor. Then, just record it. Don't forget to solo right tracks.

Hope it helps.

So you can use a y-cable into the interface.

I don't want to hijack, but I have an FMR RNC, and I have been trying to figure out how to use it with my Firestudio project.

Same answer except you have to do two lines for stereo.

Help! Trying to figure out the correct setup for my Presonus studio channel as a pipeline plugin in S1ver2 software, to beable to use my preamp Studio Chan. to use as a vst plugin in studio one?
here's what I have:
1.Presonus Studio Channel
2.Audiobox 1818vsl

I need cable settings like inputs and outs.
