"That's exactly why the same amp or drive setting won't also work on your real cab"
Because they only capture the frequency response of that snapshot, they don't capture the dynamics and distortion introduced by power amp/speaker/mic/preamp. They are not "3D snapshots", that's why initially I suggested to experiment with speaker drive and motor drive parameters.
I said:
"I still see no reason why it should be so difficult to use a single snapshot of a mic position to reproduce both a clean tone and a dirty tone when doing so with a real mic is not difficult at all."
You said:
"You admitted that it's not difficult at all if you're creating your sound for the FRFR out."
Right.
If I use a different instance (including different IRs and/or EQ) of the Cab Block for each separate Amp Block instance I can get satisfactory results.
But I'm trying to do this with a single instance of the Cab block and your explanations as to why this does not work so well don't really seem to be on the mark, as far as I can tell.
It's pretty simple to make them work both on the same IR: just tweak the amps and drive blocks you're using instead of the cab block!
But you don't want to do this because it would screw up your PA+cab sound..
And that's totally normal because, again, the IRs are not 3D snapshots.
You're assuming that
amp sim+PA+cab+mic+preamp=amp sim+IR but that's not right for the reasons I said above. Even if your power, speakers, mic and preamp are the most transparent on the market they still introduce some compression and distortion, they're not a $20k Hi-Fi system!
You said:
"Again, what's causing you this problem is that you are comparing amp-in-the-room sound (your power amp and cab unmic'd) to an FRFR sound.
For some reason you don't want to accept this statement but that's what it is"
It may well be at the root of my issue.
But I still don't understand how or why.
That's not clear in reality because in some posts you talk about unmic'd cab and in some posts of a mic'd cab..
You said:
"In my #1 I was talking about making sound your Frfr as similar as possible to your unmic'd cab = try to achieve amp-in-the-room sound with an IR"
Well that's what I used to try to do.
What I do now is to try to get a satisfactory sounding mic'd cab sound coming out of my FRFR speaker, a CLR in this case.
And I still don't understand why an IR that works well enough as a representation of my mic'd cab for a clean tone does not work equally well as a representation of my cab mic'd exactly the same way with an overdriven tone because with a real mic it DOES work.
Well, at least that's a step forward!
It does not work for the reasons I said above, you're not tweaking your amps/drives to adapt to the IR and you're arbitrarily taking out of the equation the non-linear effects of your pa/speaker/mic/preamp setup.
Even if you shoot an IR of your mic'd cab you'll still have the same problem because those non-linear effects are missing. The best you can do is trying to simulate them inside the axe fx.
Or, now that I think about it maybe there's a better alternative: use 2 amps in your presets, one tweaked for the IR and one tweaked for your cab. Done
