Maybe slightly better idea is to move stack section backward and forward from -4 to 4 with this number displayed per Rig basis. It is simpler than defining each FX position and will do exactly the same.
-4 -> before FX A

-3 -> after FX A
-2-> after B
-1 -> after C

0 default (after D)

+1 after X
+2 after MOD

+3 after DLY

+4 after REV

I think my idea is possible even for MKI and MKII users with some complications on the way in case of parallel path and with Stereo effects. But it can be restricted to no parallel path and only after+0 stereo FX are allowable. Its just "simple" rerouting .

have a faith:) Guys are observing what's possible to implement. The "Lock all but " in RM was after Toast ME as this was brilliant idea from the users

The thing about NAM2 is that the snapshot might be good but the problem is the rest of the stuff that Kemper can do besides sound like an amplifier.

I believe that chasing "real tones" is pase.

I mean, would you say that old tvs are better than the ones we have today? or that the picture quality was better before than the one we have today.

The radio sound compare to streaming music at high quality?

Why bother looking for an amp sound that is never consisdent and dependant of many factors to make it sound good. This is why every good or high quality studio have kempers lying around because this gives them the consistent sound they need to produce good records.

We should not be searching to capture old equipment instead making this new equipment sound good in the context of mixes and in live situations. Kemper does exactly that.

We are living the dream right now, we can do so much with the kemper that to me is just waste of time to keep looking to recreate a sound that is already there.

You are still speaking from the perspective of the player not studio guy that want to reamp the guitar part with exact the same sound as first take.
NOTE : play feeling is not important here as already recorded DI will be used.

Since this is a wish list - give me the ability to move around the effects block before and after the amp. Being locked into 4 before and 4 after doesn't always work - sometimes I need 5 after the amp if I'm using one rig for multiple songs.

what do you mean on another device? You mean an external device that is able to load NAM A2 profiles? If so, that's not surprising because the device is taking care of the levels on input, presenting the guitar with a 1 megaohm load and dealing with an calibration issues internally

Quote from jzucker

I've never once overloaded it using humbuckers and 3 stacked overdrives.

Maybe because you’re not using dedicated hardware, as you mentioned in the other thread. If, for example, Fractal were a VST plugin, it would probably have the same problem you’re describing.

Are you sure ? you can overload kemper or fractal too with to hot signal.

Have you checked calibration levels ?

Steps to Calibrate NAM Input

• Turn down interface gain: Turn the instrument/input gain knob on your audio interface all the way down (or to a known baseline). [1, 2]
• Check interface specs: Look up the maximum input level (measured in dBu) before clipping for your specific audio interface in its manual (common interfaces are around 12 dBu, while pro units can be 18 dBu). [1, 2]
• Enter value in plugin: Open the NAM plugin, enable the "calibrate input" option, and enter your audio interface's maximum dBu input level. [1, 2]
• Adjust for A2 profiles: When using newer slimmable NAM A2 profiles (which support full and light execution modes), ensure your input headroom matches the metadata so clean profiles do not sound overly gained-up and distorted profiles do not sound weak.

I think you nailed it.

The 2 use cases ( studio vs live) are very different and we have had the luxury of a unit that covers both very well.

are you sure ? I have two tracks l+R to track. Can i use one KPA to do this on one take ?

Can we mark this as the best answer and close this thread?

No — because you’re a player, not a producer, and the answer concerns players only.

If any part of this discussion makes you uncomfortable, you can simply unsubscribe or stop watching.

I really dislike when people try to shut down conversations about real issues and silence anyone who has a different opinion.

Quote from GCNC8068

I agree with Scott Uhl’s view. Especially the part about features now being more important than profile/capture accuracy - because we’re already at the point where all similar quality hardware produces excellent amp tones. Excellent amp tones are now “table stakes” for any product - they will be the arena of cork sniffers to fight in

The user interfaces, controls, ease of use, I/O, etc., are now the battlefield.

This is why the MK2 was disappointing for me. Few user feature upgrades in favor of more “accurate” profiles.

I do not agree. It depends entirely on the use case. If you’re in the studio, you want to track guitar parts with maximum accuracy, because there will always be some fixes, edits, or re‑takes. A hardware device can only track one signal in real time. NAM can track multiple tracks in bounce mode — faster than real time — and with higher accuracy.

So for studio work inside a DAW, NAM is the better choice. For live use — a hardware device wins.

Most influencers talk only about live performance, which is just half of the story. For live shows or simply playing for fun, I prefer a hardware unit. For tracking and full DAW projects, NAM is my first choice now.

Why? Because it’s not only about “does it sound good.” It’s about “does it sound indistinguishable from the rest of the track in this exact setup.”

So for me it is a more perfect “Sound Copy” machine for studio use — not just because it sounds good, but because it preserves the exact tone. If you need to retake some parts after your whole hardware setup (amp + cab + mic positioning + mixing chain) has already been taken out of the studio, NAM is the best choice IMHO. All you need is one training take of that exact setup for the session, and you can reuse it later.

Yes, sure — you can buy four Kempers to track L+R rhythm and one doubled solo in real time. But with NAM I can do this in bounce mode, not only real time, and I don’t have to buy four expensive devices.

And I still think that people who deny it may simply be speaking from within their own bubble of experience.

For studio it saves time , it saves money , it preserves the tone.
(and to be clear: I’m talking strictly about amp‑only amp sound emulation — not about additional effects, where Kemper is genuinely excellent).

But back on the topic why i think it is not possible to do on our KPA DSP :
I'm not sure if anyone would even attempt to port the entire NAM and Eigen math libraries to the Motorola/Freescale DSP56300 family.

Write a fixed‑point backend from scratch for all Eigen math operations — that’s thousands of functions. The DSP56300 doesn’t even have native floating‑point multiplication

1.Rewrite NAM in fixed‑point and manually scale every tensor.

2.Optimize everything for a 24‑bit MAC and a 150–200 MHz clock.

3.Shrink the NAM models by a factor of 100, because the DSP simply can’t store them.

I'm all for this feature, but I don't believe it's possible.

That will almost certainly never happen. The Virus never got a substantial architectural upgrade and the Kemper has followed the same pattern.

It is no surprise that there hasn't been a new generation KPA. The processing hardware is obsolete and there is no newer version to be had. Kemper has chosen to tie themselves closely to that processor, so they are not free to move to newer processors like their competitors can do. The response to the video that shows there was no significant processing update in the Mk2 should be "Of course there wasn't a change, what did you expect?".

There are pros and cons to this approach. It means there will never be a new generation Kemper, but it also means Kemper has been able to be very efficient and squeeze the maximum out of that Freescale chip. It's a miracle they've been able to do as much as they have with it.

Yep, and the DSP56300 family does exist in dual-core variants, so there's theoretically a bit more headroom there. But I'm not sure that would win the fight against neural networks anyway.

When it comes to new technology, the question isn’t if — it’s when.

I'm mostly using free BandLab Sonar, Mixbus, and UAD Luna.

Quote from StefanErtle

Well in the end it’s like having a car that has a digital display instead of „old fashioned“ indicators for rpm and speed. Does that make any difference apart from visual sensation?

Then getting 150 hps more currently having a 911 from Porsche with already 400 hps … how can I make use of more … and that couldn’t provide basic feel of a good guitarist that even outperforms me even on the cheapest amp imaginable…

Dare to say that my KPP has no display and I don‘t mind. All I need is to know what rig is selected. So far so great. Kemper will survive that spec-chasers …

My point was to have all the great FX available for live playing, plus some of the tone-shaping parameters like Pick or Compression — but also have the possibility to loop in a custom amp, cab, or both. If this could be programmed with MIDI switching, it's a win-win situation. You could even loop in a real Mesa Mark VI, just to still use the Profiler's genius FX on top of it.


Just to be clear — this was never about claiming an external amp sounds "better" than Kemper's own modeling. I'm not chasing specs or making an A/B "who wins" argument.

My point is purely about workflow and live routing flexibility. The Effects Loop already shows Kemper is fine with external gear being part of the signal path — I'm just asking for that same flexibility one step further: an option to route an external amp/cab source in at that same position, while keeping the Tone Stack, Pick, Compression, and — most importantly for live use — all the FX slots and MIDI switching that make the Profiler what it is.

Also, given that native NAM support isn't realistically possible on the KPA's current hardware, this kind of loop would actually be a workaround for that whole discussion — instead of asking Kemper to run a neural model internally, you'd let people bring their own external NAM/amp source and still keep everything that makes the Profiler great around it.

If someone doesn't need this, that's completely fine — it wouldn't change anything for them. It's a routing option for people who already own other gear and want to keep using Kemper's FX engine and live workflow around it, not a statement that Kemper's own modeling needs replacing.

Well open source and free is a fair price for what you can do with it

Actually I'm not sure if it's possible but I would have a feature request:

Add some kind of "smart loop" that could replace the nonlinearity (the Amp block), the Cab, or both — instead of just adding to the signal like the current Effects Loop does.

The idea is: I could plug in an external amp/preamp source and have it "sit" exactly where your Amp or Cab normally is, but still keep your Tone Stack and all the FX slots working like normal.

One more thing worth considering: it would be great if some of the character-shaping options that currently live in the Amp/Cab modules could still apply to the external signal — things like Pick (pick attack/response behavior), the Compression that's part of the AMP module, and the option to still apply the Liquid Stack EQ on top.

Basically a way to swap out just the amp/cab "core" (selectable AMP OR CAB OR BOTH) while keeping everything else (Tone Stack, Cab if I want it, Pick/Compression behavior, Liquid Stack EQ, and all FX) working as-is.

Not sure how deep this would need to go on KPA Team end, but wanted to throw the idea out there.

Quote from V8guitar

Entertaining and some good points but...the pros and cons of open source remain. Without the join up with hardware its still fragmented and will take time to settle in.

This is nothing surprising, once technology hits a certain point, then quality remains consistent and it prices drop and cheaper ways to access the tech are found...which is what is happening. It is interesting that the claims involve dismissing established tech - There were loads of kemper blind tests back in the day and few could tell the difference. We are saying that NAM can do that better?

So what do guitar players do in the meantime? either work around the compromises or buy what is system ready. I'm not wasting my money buying a Kemper Mk2 stage, I'm buying a solution I can use right now, works and sounds amazing. By the time this really has an impact, I will have got my moneys worth already.

Not sure if you're up to date, but tons of hardware vendors have jumped in recently. For clarity — my trusty KPA rack still sits on the desk, and I’m perfectly happy jamming on a single profile.

unpopular opinion ....

Or even better - wire that sensor to the display and let it hype you up depending on how hard the floor is shaking

light rumble: "nice groove"
a bit more: "now we're talking!"
floor properly shaking: "THE FLOOR IS SHAKING, KEEP GOING!!"
full earthquake mode: "I can't take it anymore, Dave"

An amp that actually feels the energy in the room and cheers you on. Completely useless, absolutely necessary.
Not for Player users though want the hype, you gotta own a model with a display.

and after a kick? "ahh sorry, firing up the springs"
