Summerize 4 CABS

[blackland]

Hi,

I did lots of IRs myself in the past. Now, after 2 years of tweaking, I have found my perfect sound. The preset is runing 1 Cab-Block with all 4 CABS active. Each of the 4 CABS is little tweaked within the block parameters for each cab (gain, pan etc.) . Since I am happy with the result I would like to save some CPU usage (which I need for other purposes). I tried shooting an IR of the block (pink noise/ white noise in synth, tone matching block).

The resulting IR was pretty disappointing to my ears, there was a feeling of much less resolution and separation in the resulting cab IR than in the sum signal of the original cab block.
I think this could be partly connected to the fact that I had used slight stereo panning in the cab block and the resulting IR is mono, but I think that fact alone cannot be responsible for the (relatively) big difference between the results. Its not like salt and suggar, but the difference is definetely audible.

Would I be able to tweak the 4 CAB IRS in the CAB block in CABLAB with same parameters like in the Axe and export a better IR as result (or maybe two, one for each side of the stereo field, so I could maybe use 2 instead o 4)? I would consider buying CABLAB if this would be definetely possible and would provide me a result which would be closer to my original.

Yes.

Try your original 4 cabs with everything panned center. Does that sound the same as your combined one?

This feature would be a great addon to AxeEdit, from the Cab-Block save/export as new IR.
But this would take away the extra $$ for cab-lab and the ability to rip the factorys cabs.
However from user perspective it would be more user-friendly and saves some CPU for other stuff.

no it doesnt. It is little hard to explain but the combined IR sounds little less brilliant and detailed.

I think the problem besides of panning comes from the pink/white noise and sample/integration time and this somehow flattens out the signal.
I would prefer just fft-ing the IR and doing it just mathematically with convolution,so there would not happen too much error/loss by sampling/averaging. Performing this programmatically is not a problem,I was writing some code a while ago which can do this easily,but since I was little manipulation the individual cab IR in the AXEIII itself, with those unknown "FAS-parameters" the result would be different of course from just a convoluttion of those 4 IRs.
Thats why I asked about CABLAB. if it would let me access the same parameters as the AXE for each IR and them adding them, I would go forit.
If it just lets me convolute the 4 IR to one without this possibility it wouldn´t help me.
