NAM: Neural Amp Modeler

@Sedaxel "So for NAM to be an option in that use case, I thing is crucial to normalize input gain and let the profiles (free or paid) be reliably available to avoid guessing. "

That will only be possible if everyone would use the same hardware for reamping (or list their dBu levels)
Yep - until users AND software developers acknowledge the subject and make it easy for users, all-in-one platforms have an advantage for consistency in this regard. Nothing that can’t be solved though but it requires a pro-active approach

Yeah, probably.

But there's a couple hopes, though.

One could be the Tonocracy way. To add a little calibration tool into NAM software to make easy to train the profiles with some kind of standardized gain. Yeah, it's not perfect, and lots of users won't do it right.

The other way could be to modify the trainer software to work different... Maybe in the style of Mooer GE Labs, which takes into consideration levels from the audio interface and stops the process if there are deviations.

But I'm only speaking without knowing a word about software programming. And I don't know either if that would be possible.

For me, that's the great (but really really great) advantage of Kemper and QC.

I use NAM with my own profiles because I know exactly how they must sound. But I have zero interest in loading 3rd party profiles because I'll never know if I'm experiencing a close behaviour to the real amp or not. However, I'm always considering to put my hands on a Kemper, even with its lower accuracy, because of the huge collection of profiles that for sure are fantastic.

@ArteraDSP I’m giving GigFast a few spins and everything is pretty straightforward to use which is awesome.
For getting an input reading it would be cool if GigFast could give us a -dbfs input readout like Logic here. I know screen real estate is everything so maybe even if you tap the input it pops up a more zoomed in view with a good reading etc.

(Running an IPad Air 4th gen with Audient ID14mk2 here for anyone wondering the setup)

For the people that care (I mean most people should but that’s another topic) it’s basically mandatory to get a good reading of the input so we can adjust profiles to match. There are ways you could even expand this topic with capture metadata or saved scenes, but again that’s a whole other scope of development. Just having a nice legible input reading would be a great step. I had to install logic and signup for their trial because so many iOS apps don’t have this kind of info, if GigFast can have it right there, super handy stuff!

Also do you know what the GigFast amp models are calibrated to so we can match?

Thanks, your feedback is well noted. We will try to figure out a way to implement better reading. For GigFast amps since they are parametric and gain is behaving like actual amp gain what we suggest is to leave your interface input gain at minimum. You will be fine if you are hitting -18 to -12 range.

Has anyone / does anyone use a pedal sized interface for this kind of thing? I see this Teisco one is pretty reasonable but not sure if there's some drawback on latency or something I'm missing vs a portable interface?

Ironically the IK iRig Stomp with an ipad running gigrig lite would be an awesome little setup for its built in interface, ipad holder and switches all built into one. NAM running on ios just opens up the door for more pedalboard options.

I actually have a MeloAudio ToneShifter Mega I may have to pull out for this:

I don't think those are still in production though; but I expect it to work with a new iOS device, since it is class compliant and works with Macs and past Phones, would just need a Microusb to USBc cable which I already have... Might be kinda fun to drag out and A/B vs the ToneX pedal.

Yeah that's the sucky thing, re NAM... it's doomed to be unstandardized in this regard. No way to get that milk back in the carton, IMHO.

I don't think you are likely to get adoption of most of the ideas above from others without a concerted effort. You'd need a vendor to drive or someone who was profiting from it to take the reins, for that to happen, I think; and you'd still have all the new non-standard profiles have been created and are being created every single day that are out of whack until then. So it is very likely a lost cause.

The XSonic XTone inteface pedals seem like they are well designed. Never tried one.

No: Your screen is not cracked. That's part of the image. Got me for a second....
 
I tried both, the Melo Audio (there is a rebranded model in uncle Thomm, named MP500 or something like that) and the Xtone Pro.

Didn´t like any of them.

The Melo was limited in the MIDI CC implementation (you can´t define the value of a CC number). Moreover, the audio convertion is bad. When I recorded a take and watched its wave in a DAW, it was offset with respect to zero axis. And the peaks appeared to be much less defined than the same kind of recording through my EVO4. Besides, the built in analog boost of the input was noisy... it worsened considerably the input signa, it was basicly unusable. I think this device is just garbage, sorry.

And the Xtone Pro... I found it also very limited in the MIDI implementation. I don´t remember too well what was the problem. If I recall, I think it was that you couldn´t choose which CC to send or something like that (sorry, don´t have a fresh idea about it)... like if it was intended for using the MIDI learn funtion in the plugins. Another BIG issue is that the input was NOISY if I used a mic. I had to put in the middle a little 1:1 isolator to get rid of the noise. And finally... the guitar input had no gain regulation, no knob or whatever. Even when you can use the "new trend" of using minimum gain input for correct use of guitar plugins, it´s not a bad thing to have some kind of regulation. Then, taking into account the bad quality of the AD converters in the Melo Audio, I kind of have little trust in these chinese interfaces converter quality. If We are so enthusiastic about the accuracy and quality of NAM, it´s a real waste to use bad quallity interfaces, really.

The quality of these devices, in terms of AD/DA is not reviewed anywherre. We only have the marketing word of both companies (high quality 192kHz 24bit audio!!!)... but honestly, I think that, if someone made a serious review with measurements and so, We´d discover that all tha giltters is not gold.

They also claim "ultra low latency!!!"... I didn´t notice less latency with than a Zoom U-44 which I had at the time, either. I don´t remember if I made some RTL measure in that moment, but wasn´t specially impressed by that.

Some good observations... If someone were incorporating this into a live rig they might want to look at other options based on the above... There are plenty of compact interfaces that would be small enough to mount on a board. You don't really need an interface with a footswitch if you have some kind of FX loop/Line selector type pedal and iOS devices can use any class compliant interface.

Messing with Gigfast on the phone and an Apogee JAM+ yesterday with headphones was really fun, was super easy to import NAM profiles and IRs definitely a cool development.
