The OPUS does everything well...HOWEVER, you need to know (if you don't) that that tool group is POST-Cabinet IR, not just on the preamp/power amp section. The OPUS is, at its heart, a recording solution that has a "master EQ" before it leaves the box. I run compression at the front of the signal chain.
Now, you can do as I do and apply the Cab IR (with OPUS EQ) to the DI only and run the preamp/power amp IR section (without OPUS EQ) to the 1/4" output. It is recommended that Delay and Reverb be done AFTER the OPUS. I run a wet stereo effects line in this manner. I run the EQ2 as a wet stereo effects loop master EQ at the end of the loop before the L/R desk/FOH outputs.

A word about OPUS midi and SA pedals. I have a full midi SA pedal (EQ2) and a midi capable pedal (SPECTRUM). The Spectrum requires the SA 168 midi adapter ($49).

You can run the OPUS off this adapter from the 1/8" TRS THRU with a standard Boss midi cable. The OPUS has only midi in, not out/thru.
I hope this helps...
