Autogain for guitar inputs

Hi new here and don’t even have my unit yet🙃 but applying an autogain feature on the input would be the easiest solution… Don’t know how hard that would be for the programming team to get up and running but makes alot of sense to me… And would save you having to save all those guitar input presets… Just plug and play

This my answer to another feature request and then thought I should put it up as an actual request… As said new here so hope nobody minds me doing this…oh can’t wait to get the quad cortex I use the plugins and love em :crossed_fingers:

Hey and welcome :smiley:

Is there anything like this on other products you have used?
I’m having a hard time imagining how this could possibly work.
Mainly:

  1. How is the the QC supposed to know which guitar is connected?
  2. How would the QC know if the connected guitar has low output pickups or just the volume knob is rolled off.

This reminds me a lot of the general discussion about input gain in modelers and plugins.

On one side there is the argument, that if you want the modeler to react exactly like the amp, then you shouldn’t change gain between instruments. A real amp would react differently to low and high output pickups after all.

On the other side are those who don’t care about “realism” and just want their input gain normalized across different instruments. (which I think is what you are going for with this feature request)

Both are are valid, depending on what you are trying to achieve. But I don’t see how the normalization could be completely automated.

Hi and very good points you have said… It was an answer to somone elses feature request… And they were saying they are having to save settings for higher gain pickups and lower gain pups and I guess i just said auto gain would probably be the simplist way of doing this and you wouldn’t need to be setting up different profiles for different guitars. Which suggested to me they want to keep the levels in check.

Maybe i took them up wrong and if I did then I’ll apoligise for it… But as you say some like to have everything level and some will want the amp to behave like in the real world… Higher output pups will push the preamp more…

Autogain is on audio interfaces like presonus/evo and others and there is also plugins that auto gain inputs…and like anything if you don’t like it on you don’t have to switch it on…

And having about 20 guitars behind me and using them at different times and it may be more useful in certain scenarios :grin:

Auto gain is a feature that automatically adjusts the input level to the optimal setting, ensuring your recordings are neither too quiet nor too loud. This is great for beginners as it simplifies the setup process, getting rid of the need to manually set gain levels. With auto gain, you achieve the right balance quickly, preventing distortion and maintaining sound quality.

It would also just be on pluging in your guitar bass etc get your instrument to max volume and turn on auto gain let it do its listening and then it’s done…

And also some people might find it easier to just save profiles… And I’m also happy to delete all this, but once it’s done it’s adjustments it usually only takes a couple of seconds to do it then it’s done… You can then turn your volume up or down as you wish

Oh so it’s like a short “calibration phase” where it would listen for peak volume and adjust the gain so it isn’t clipping? Like a tuner, only for input volume.

Yeah imagine that could be helpful if you switch instruments often and want to have one baseline input level.
It would also mean that you don’t have to eyeball the peak volume on the gauge, but let QC measure it.

Maybe there are other users who would like this and this gathers some votes. Let’s wait and see.

Yes and worded very well… I probably should have been more specific or a better explanation… Well I’d find it helpful with my collection

This makes sense to me, not only for the QC, but also for the plugins. Let me say that I agree with @derdoe in that there’s a lot in the input signal chain that is very subjective, but I think that both the QC and the plugins could “learn” (using machine learning techniques that Neural already uses) from the plugged in instrument (as you play), and make suggestions based on some preset parameter defined at the time of the capture or definition of the amp model (similar to what they did with the automated gain detection for the captures).
But again, these should be suggestions: in the end, there’s nothing wrong with pushing an amp a bit more (or less)… it’s just a different sound. This feature would be useful for people that want to get the sounds closest to what the author of the capture/model intended.

While there is no wrong way to go about it there are “best practices” and and auto-level/auto-gain calibration feature would encourage that.
strange thing is the QC has an auto-set input function during the capture process so it can be done.

in my experience biasfx 2 has a quick auto set input gain that takes 2 second to do

When I put up the feature request it was in response to another thread… Anyway it’s on a few audio interfaces. Focusrite and evo by audient… It makes it easy for folks that just can’t seem to figure out how to set levels… And I’ve alot of guitars with different pickups so it was more for the handy side of things… It should be able to monitor the signal automatically… So once you clip it adjusts itself to an optimised level…likewise if your input level is low from low output pickups it brings it up…and once the calibration is done it sets it at an optimal level more so you don’t clip and when finished you can roll of the volume on your guitar if that’s what you to do style wise

Also I don’t have any issue with noise or the amps not sounding rite nor do I have an issue with setting my input levels… But some players seem to be struggling with it so thought it mite very suitable to them

that’s cool, im remember that feature from the alien connections revalver 2, before peavey bought it. that’s like almost 20 years ago

I understand the idea and I’m not arguing against it, just want to share my thoughts.
Isn’t a single coil supposed to have less gain than a humbucker when using the same amp settings?
The calibration would definitely make sense for very high and low output pickups. On the other hand it would also level out all intended differences, or am I wrong?
It would mean we could then use the same presets and same amp settings on all guitars and get a similar result. But is that what we really want?

It isn’t somtin you have to use… It’s on the input and it’s to stop clipping… More so than anything else… Same if you were to set it manually you would set it to were it wouldn’t clip for both single and humbuckers or hot vs low outputs…

If use my tele say I bring up the input gain until it clips and then roll it off to were it doesn’t… And same goes for my hot and humbucker guitars they output different and I have to set them individually… From what I can tell I have to do that with every guitar I use… So it’s only taking the hassle out of doing it manually especially when I could change a guitar alot in a live situation… Drop down menu tap input one play guitar and it sets itself when it’s calibrating your input it switches off the output like in tuner mode… Saves on the trying to fine tune it in a gig…

Ah ok, understood. Maybe it’s because I only use two guitars and always leave the input gain at 0.
But I can understand it makes sense if you have lots of guitars and always want to use the full resolution on the input.

Not really cause humbuckers sound completely different to single coils and the push in a different manner on the input and a single coil played in a preset made up for humbuckers would sound thin and treble forward generally …and humbuckers would sound to dark and muffled in a single coil preset
