store a preset correction of high-mid-low knobs per song

[Michael Stahl]

With some songs you have to adjust the knob's High Middle or Low again and again. It would be nice to be able to preset this difference for each song if needed.

Example:
A song lacks bass. So I have to turn the bass up every time. The pre delta for bass on this song is, let's say, +0.3. Bass is currently at -0.1. Now add both values ​​so that real bass is real reproduced at +0.2.

Certainly there will be a limit when adding both values. Probably +-1. Then that's the way it is. Because if this limit is exceeded, you are moving in extreme areas anyway.

In addition, the range for this pre delta could be specified in the program options. Instead of -1 to +1, you could then specify yourself for finer adjustment, e.g. -0.5 to +0.5.

The design of the High, Middle and LOW knob's to see the pre delta of a song could be a tandem knob (poti) or an LED circle around the knob.

There are more benefits.
1. It won't forget to undo the change on the next song in that deck.
2. Once you have set the songs that need to be readjusted, you don't have to constantly readjust them and lose time.
3. The AutoDJ also benefits from better sound.

Thank's

Before (in the forum thread) I assumed you request setting the EQ knobs directly.
Though, now there should be invisible EQ knob adjustments per song.

Apart from the issue described in the bug title, you describe other issues/solutions.
Can you describe them in other bugs in the form to describe the issue you like to solve, you use case and the proposed solution? Thanks.

[Daniel Schürmann (daschuer)]

I cannot really confirm the original bug, and think that is a candidate for won't fix.

Reasons:
* The main use case for the EQs is mixing, using them during transitions and make the sound compatible, create transition effects.
* Tracks are recorded/produced with a sound that normally is already compatible to the genre and year it has been produced. A invisible EQ preset will destroy that like every other filter applied to the original sound.
* The final sound heavily depends on the PA system, the adjusted sound is probably valid for the whole combination. There is no "normal" to decide which of both tracks needs to be adjusted.
* Mixxx allows to use various EQs, so writing the EQ gain by track is not universal correct.

If you have a track let's say from 90th techno and Mixxx it with a recent club track it sounds kind of flat and takes power from the dancefloor. You may want to use a recent remix instead that is compatible.
In that sence, I suggest to "remix" it yourself and record it with new EQ settings applied.
This way you have both tracks in your library.

Does this make sence?

I also don't think we should implement this and agree with all of the reasons Daniel gives. Processing the track yourself is the standard, and these are called "DJ Edits". This is the better way to handle the situation.

This is a wish and not a bug. Here are a few of my thoughts.

First I have to ask which program, preferably free of charge, do you use for the "DJ Set"?
I believe that it is possible to adjust the sound with expensive programs. This is certainly the best way to set the optimum.

But this is more likely to apply to professional DJs. I don't know how many Mixxx users are professional DJ's and they also create a DJ set. Full time professional for sure.
For the rest, almost all private and certainly a lot of hobby DJs, this is not the case. And it is precisely for these people that this wish is ideal, as they save themselves turning the high-mis-low knobs.

In addition, they are probably overwhelmed with creating a reasonable "DJ Set". And that's exactly what helps them immensely. Whether this method is professional or not. See forum thread. I have already been asked by friends if I know of a program that fulfills exactly this wish.

The volume of a song is corrected with great effort. And that's what I love about Mixxx. On the other hand, the volume correction could also be done with the "DJ Set"?

The setup on the PA is of course done in the options under Equilizer. Clear.

I have a large PA in the basement and a studio system in the living room. I simply synchronize the Mixxx SQL and the songs with a NAS. In the Auto DJ I have >2000 songs. From the mid 60's to today. When there are visitors, there is something for everyone because everything is played mixed. From this experience I can say that there are songs that sound better on both systems if you turn up the treble a bit, for example. And this high-mid-low differenz is to do with same song, same set on both systems.

You can already play and record a track with different EQ settings applied.
The other effordable option is using Audacity.

You demand with the higher terrible sounds as if you are locking for the loudness effect.
This can be used when playing tracks with reduce volume during warm up.

By the way, Mixxx is free software. So you are always free to propose a PR with the requested changes. You can use it in your privat build and maybe you find enough support that it is integrated in the main branch.
