Anyone Want to Test This Beta Firmware

The genius that made my guitar discussing stuff I dont understand with the genius who made my processor. How cool is that. And I've read it. Twice. To think I took up the guitar thirty years ago just to get laid (didnt work btw).
If you guys need any further input from me I'll be out back listening to motorhead..........

We live in damn good times to be guitar players...
 
Can someone confirm whether this technology can be used to flatten the response of a poweramp into real cab (Matrix GT800) for better accuracy in live use? I have read the thread and see it discussed but I am not as smart as I'd like to be.

You missed page 1. :)

Would this also be beneficial for live power amp and cab users? Would this allow us to flatten the response of our poweramp before it hits a real cab like a 4x12?

No, this is for capturing IRs.

Of course I read that from the man, but what about the suggestion of using a flat cable to capture a null IR on one side, then the compensation component would could be an IR placed before the real cab to cancel out it's inaccuracies? Maybe I'm still way off.

Which inaccuracies? A real cab is what it is: a real cab.

You can't transform a traditional cab into FRFR because the speaker is not full-range.
 
As I understand it, the new IR capture process allows simultaneous capture of the mic/preamp signal and also the errors of the poweramp connected to a speaker load. Why not just capture the errors and use that as a kind of inverse IR to correct the poweramp into that cab?

Cause powertubes might behave a little different day to day or somethin'?

Yek, i believe you misinterprete. As i understood, he wants to exclude the inaccuracies of his power amp, resulting from the speakers load influencing the power amps "flatness". Refering to Cliffs measurments with a GT1000, he introduced "reference IR" measurment. But if "reference IR compensation" is valid for IR capturing, why wouldn`t it be also valid for PowerAmp-Correction when audition the real Cab by ear (instead of audition the miced recorded IR) ?!

That`s what i`m talking about the last days all over the place. The ability to export just the inverted reference IR standalone would accomplish this target.

Because i believe the impact of Power Amp correction will be valid, but always smaller, than the given speaker impedance of the actual cab (refering to SS-Amps), the simulation of this (SPEAKER TAB) have to be also be accurately adjusted to the actual used cabinet. Reading out the resonance peak for speaker tab adjustment will help, to get more accuracy results, playing a Axe-Fx Sim via (reference corrected Amp IR) through the actual cabinet in comparison playing the actual real Amp directly to the same actual cabinet.

The manual for the Pro D2 makes no claim of being able to handle speaker-level signals, and the maximum input is rated at +18 dB. So I would say no.
 
I tried to capture IR with the new method (Mic + Boogie MkV Slave Output) with no good result , i prefere the Mic Only method by far . Big hum too with the Mk5 slave output ...

It's probably that hum that's causing your IR capture problems.

If you have lots of hum that will ruin the IR. Use a humbuster cable between the Axe-Fx II and the amp input and that will get rid of the hum.

Tried with humbuster cable (Axe XL output 2 left to power amp return MkV) here the result : Mic only Capture and Mic + DI capture . What s wrong ...?
