[Feature request] MIDI control and fader groups

[die-gute-snefi]

First of all, thank you for all your work! The new qt UI looks amazing!

I saw in the web UI, that you've already included a toggle to turn on and off fader groups. Would it be possible to implement a way to remember them and easily connect a MIDI device for control such as in TM FX?

My setup when I was still using Windows was as follows:
In my UCXII I was using 2 Speakers (main) + one subwoofer on ChOut3, crossover handled by RoomEQ. Changing volume obviously requires use of a fader group to change both main and Ch3 simultaneously. This I further did by using a small microcontroller with a rotary encoder registering as a MIDI device (see here). This also allowed me to switch between headphones and speaker control with the press of a button.

I would adore being able to use this kind of setup again under linux; but trying to pipe the output of the uC to the interface didn't quite work out, possibly because the command structure may be different (under windows this had to be specifically enabled after all). Working around a missing fader group while sending MIDI should be trivial, but an easy setup option to allow MIDI control would be ideal.

Another issue ( but this may be a limitation of CC mode, I'm not sure) is the lack of the software "remembering" or reading out the values set in the interface. Are there plans for this, or is this even possible?

Thank you again for your effort!

Hi, thanks for your input.

Yes, it was a preliminary toggle, not implemented till now (intended sth similar with TM "ad-hoc" fader group). Well now I did at least the basic functionality. So this should work now for you. See: 92ffea4
Let me know if you encounter issues with the ad-hoc fadergroup in the web ui.

Regarding MIDI assignments for the controls: Yes, MIDI control is on my list too, but other things/bugs have a higher priority for me atm... But you can be sure, its on my mind. Additionally, implementing an additional MIDI core-layer for all the controls isn't as trivial at it seems.

Another issue ( but this may be a limitation of CC mode, I'm not sure) is the lack of the software "remembering" or reading out the values set in the interface. Are there plans for this, or is this even possible?

Well, the information stored in a unit is not fulfilling a complete state of the mixer at all. Although the almost all information is sent, some are missing (like playbacks, etc)....
Additionally some units send more infos, some older less (afaik my ff 802 doesnt store channel names for example).

However, it should be possible to be able to store the overall ui mixer state with all controls' values and recall (and send) them on startup/selecting a saved session (=snapshot in TM terms).
As, I had this already in mind, too, I played with this concept in the roomEq WebUI window, which already works quite well. Here, the store/"remember" concept consists of three options:

1. local starage of browser is used via the presets..
2. you can download the current roomEQ settings as json file locally, and upload it later to any other browser/ machine
3. Even the original Totalmix .tmreq file format is already supported here. That means - you can export your roomEQ settings from TM running on your windows machine, and import it here - or vice-versa...

So, finally - this concept worked for my case till now. If you could play try that and report your insights, it would be helpful... So I would hook this concept up and try to adapt it at a later time into the complete mixer webUI.

PS: Of course - all of this is planned to be implemented into the qt ui, too. Feel free to try out the early-stage-preliminary alpha qt AppImage from https://github.com/huddx01/oscmix/releases
But only on non-production environment!
