GT-1000 with 3rd party IR sounds diferent than IR loader

I did a comparison using the same IR both in the gt-1000 and with a IR loader (Nad IR). The amp was the same, the gt1000s Rectifier model. Somehow it sounds diferent, but why? Its literally the same IR file. The GT-1000 (with the IR internaly in the system) made the IR sound worse.

 
That’s interesting. Converters maybe? I dunno but even using something that should be transparent (EQ-200) I heard colorization even with the EQ bypassed.
 
Yeah, it seems like they get smaller/brighter in the hardware. To me it almost seems like part of the amp modeling is done at the cabinet stage and using a third party IR loses something in the lows/low mids. Setting it to “off” in the output on the pedal versus using the IR seems to leave it intact so outside IRs sound better. Not ideal honestly. I kinda knew what I was in for with it and have been quite happy with the internal cabs for live stuff.
 
As you've not shown the GUI of NadIR in the video - thought I'd mention double checking the NadIR default settings (lo pass and resonance), and any blending / panning may change things too.

its like its compressing the IR itself.
 
What length IR did you use? what does the HW support?

Also worth checking sample rates and what is supported
boss says it supports any bit size and length.

There is no limitation on file size for IR data.
- The data is converted to a proprietary format that is optimized for the speaker simulator.

my guess is that they optimized the boss with only their IRs in mind, and the 3rd party ir support didnt get a well deversed polish

They didn't even do that. The GT-1000 originally shipped without the ability to even host IRs, that function was hastily added in a firmware update a bit later and IIRC only had four slots available to store IRs on the unit.
 
It’ll now hold 16 IRs that don’t quite sound right. There’s some sort of resonant filter (SIC? I don’t know shit about fuck) in the stock cabs and without it all the models have a weird hollow low-mids/lows thing. You CAN get them sounding pretty good with very unintuitive amp settings but it’s hardly worth it. I definitely feel like Boss modeling is an accepted compromise. I really like the X-amps and the fact that I can momentarily shoot a note 4 octaves or or have a tape-stop pitch drop based on how hard I pick without buying a 3-button brick from Fractal and it really does (to me, anyways) sound and play very well. But with Boss you pretty much get what you get. The couple of firmware updates the GT-1k did get were a surprise.
