I am guessing the drive block
Over sampling option is too much CPU for the AM4 or Cliff possibly
Tweaked some of it behind the scenes so it improves the aliasing

"NEW SPDIF Input Mode option. This setting, available only when INPUT SOURCE is set to SPDIF, determines how incoming SPDIF signals are handled by the AM4 (Left Only, Right Only, L+R Sum, Stereo). The option “LEFT ONLY” will be of special interest to those using the AM4 in a 4CM configuration with the VP4, as it can be used to reduce overall latency."

So do I understand this right?

This would allow you to receive SPDIF out from VP4 in mono? But can you split the VP4 into pre/post fx over SPDIF?

Edited.

I think to get an AM4 and integrate with the VP4 for me; I'd probably end up running the VP all post using SPDIF. Which is generally fine; provided it could do split mode out of the AM.

question to AM4 and FM3/FM9 owners did you ever clone your favorite amp through NAM? you dont need a reamp box right? just a interface?

You don't even need an interface, just the modeler. I did it for myself, but don't have them shared.

Would you share with me? did you capture with boost, etc or just the pre amp (actually the amp because fractal has power amp modeling as well)

No offense, but I don't think it's ethical to be sharing captures of amp modelers. It takes away from Fractal's work. I did it strictly for my use, when mobile on a laptop.

Did you capture using the Am4 though? No need for extra FX loop for the dry signal?

Well, in my case, the FM9. But the AM4 should work the same. I can test this weekend.

I have done it, but much preferred the captures I made of my tube amps.

Sorry, I did ToneX, not NAM. I keep thinking about messing around with making NAM captures.

Using the TOne3000 sinewave is the easiest method I think, it works for preamp, amp, power amp and full rig. I'm not sure if there are benefits or cons of this method compared to the others where you download a software and train the profiles in your own computer
Tone3000 GPU cloud will train the nam files using the sinewave up to the standard quality which is theoretically the highest, but there is also a superior one used by 2do (the user) which is even more accurate and more GPU consuming, but standard is just fine

I converted some nams to tonex and some plugins to tonex using the internal reaper routing, usually results are not great for Tonex but when it works it's wonderful. Same for nam, converted some plugins to NAM and they work great, there is also the benefit of using different VSTs to make the capture "sound better" like VST eqs, compressors or simply SSL strips to "color" the sound.

If I send you a wav or mp3 file with simple chords B, A, G, E (the chorus of Bleed the Freak alice in chains) and the free IR I did could you do the same using the Soldano model in your Fractal? I'm going to use the Soldano model from Valeton + TS9 and IR
It's been a long time since I don't play a fractal and I would like to compare both amp modeling models

I meant not saying to you send me a capture but play the exact same chords and post the mp3 of it

Here is my first AM4 attempt comparing to my Uber preamp.

Definitely happy so far but I need to disable the Mesa 5 band
