Anyone know how to get this MIDI controller working with Jambox?

The goal is to have it control the fader sliders and the mute and solo buttons.

Any clues would be greatly appreciated.

MIDI control of Jamulus is possible. I tried it with a different MIDI controller and it works pretty well (jamulus sliders move, LEDs change).
The setup to get it working is a bit complex, but I can simplify/automate it in the Jamulus startup script.
I'm close to posting a new Jambox beta release (maybe a week away), I'll include it there.
You could try to get this working yourself, but I don't advise it because I'm already doing it.

x-touch mini has endless rotary encoders, I'm not sure yet if that's an issue with Jamulus.
Jamulus does not send MIDI out, so it can't control LEDs etc on the MIDI controller.

FYI the midi flow is:
USB Midi interface (ALSA) -> "a2jmidid -e" (alsa-to-jack) -> Jamulus midi in (start Jamulus with --crtlmidich "<string>", then route with Patchage).

Things need to be started/connected in proper sequence, so it's a bit tedious to do manually.
a2jmidid is in the jambox-project apt repo, so can be installed with "sudo apt install a2jmidid"
For debug, MIDI messages can be viewed with qmidiroute (use patchage to route MIDI controller to it).

Edit 12/1/21: a2jmidid mentioned above seems to negatively impact audio, instead of a2jmidid, start jack with "-X raw" option and it will capture midi devices and present as jack ports. Instead of patchage, for midi patching I am using a python script with the mididings package (in jambox-project repo) to automatically patch, and process midi events, Most other apps which use midi are using alsa instead of jack, so the "-X raw" jack argument should only be used for Jamulus or other app which needs midi as a jack port.

I eagerly await your Jambox beta and script. Thank you!

@jazzjohn27 I posted Jambox release v1.5.0-b.1 under "releases".

Support for x-touch mini should be plug-and-play (other MIDI controllers would require a config string at least). This turned out to be a bit more complex than I expected, because x-touch mini buttons produce note on/off messages, and Jamulus requires control change messages. This required introducing a software layer between the them to toggle a button state and send control change messages to Jamulus, and LED feedback to the x-touch mini. The result works quite nicely. I made the slider control ALSA master volume. If you switch to layer B, the knobs control pan, and the slider controls ALSA capture level.

Please check it out and let me know what you think.

@jazzjohn27 That image should be plug and play with x-touch mini with default settings.

I used x-touch mini in its out-of-the-box default setup (channel 11, not in mackie control mode). If you have made any changes (which I think can be done using behringer windows app), it might not work the same.

Try the following command, it should show midi hardware devices: "amidi -l | grep hw:"

pi@jambox:~ $ amidi -l | grep hw:
IO  hw:0,0,0  X-TOUCH MINI MIDI 1

also, with jamulus running: "ps aux | grep midi"

pi@jambox:~ $ ps aux | grep midi
pi        1212  1.9  3.1 686680 123084 pts/1   SLl+ Dec01  40:03 /usr/bin/python3 /usr/local/bin/midi-jamulus-xtouchmini.py
pi        1213 15.9  4.6 420488 181804 pts/1   S<Ll+ Dec01 325:59 jamulus --nojackconnect --ctrlmidich 11;f1*8;p11*8;m19*8;s27*8
pi        3255  0.0  0.0   7348   584 pts/0    S+   13:22   0:00 grep --color=auto midi

if midi is in use with jamulus, in Patchage you should see red midi boxes connected together:

Lastly, for low level debug if the device shows up under amidi command above:

Stop jamulus to release jack from alsa midi hardware
run qmidiroute from pi -> Sound & Video menu
launch "Patchage" from destop or menu
in Patchage, connect purple alsa midi device output "X-TOUCH MINI MIDI 1" to "qmidiroute in"
qmidiroute should show events when you change x-touch mini controls:

The below changes did the trick. Plus the Mini was in MC mode. Thanks a lot. I'll put it to the test on the next jam session. Stop jamulus to release jack from alsa midi hardware run qmidiroute from pi -> Sound & Video menu launch "Patchage" from destop or menu in Patchage, connect purple alsa midi device output "X-TOUCH MINI MIDI 1" to "qmidiroute in" qmidiroute should show events when you change x-touch mini controls:

Good to hear. Taking it out of MC mode was probably the issue.

Those commands not persistent, they are only for debug; you can't use qmidiroute (to see midi messages) while running Jamulus.
That's because jamulus requires jack midi, which you get by having jack capture the alsa midi devices. But then you can't route alsa midi to qmidiroute.

When you start jamulus, the start script sets jack back to capture the alsa midi ports, and the mididings script patches the jack midi ports.

I had it out of MC mode but still didn't work until I made the connection in Patchage. Now there's a strange behavior: On a server with 4 musicians connected, the first knob worked the first screen fader, but the 6th knob worked the second fader and no other knobs worked the other two faders.

Since the strange behavior mentioned, it has worked correctly on other servers, so maybe there was an issue with the server. Overall it seems to be working fine now. Had a good jam session with 5 players and it performed well as expected.

@jazzjohn27 There is a bug in jamulus-server 3.8.1 that messes up the channel numbering, I just filed an issue: jamulussoftware/jamulus#2144
This works correctly with server 3.8.0.

If you are using MIDI control, you'll want to set client to "View" -> "Sort users by name". When using MIDI, the channel number gets prepended to the client name, so this should sort the faders in MIDI channel order. If a client disconnect, it's fader will disappear from the GUI but that will not change the channel numbers of the remaining clients (if it did the knobs would shift around).

However, channels should start again from 0 when server goes idle. That is broken in 3.8.1 which explains the behavior you saw.

I could probably change the mididings script to user Layer B for an additional 8 channels .... but that's not the answer to the server bug....

@jazzjohn27

I updated the mididings script for xtouch mini.
This one handles 16 channels, 8 on each layer.
Pushing on the encoder changes between fader (led ring fan pattern) and pan (led ring pan pattern)

You should be able to install the new script into 1.5.0-b.2 as follows:

wget  https://raw.githubusercontent.com/kdoren/jambox-pi-gen/1981124c169f363d87f0b5ab423b9caa62f45533/stage3/06-install-jamulus/files/midi-jamulus-xtouchmini-16ch.py
chmod +x midi-jamulus-xtouchmini-16ch.py
sudo cp midi-jamulus-xtouchmini-16ch.py /usr/local/bin/
https://raw.githubusercontent.com/kdoren/jambox-pi-gen/1981124c169f363d87f0b5ab423b9caa62f45533/stage3/06-install-jamulus/files/jamulus_start.sh
chmod +x jamulus_start.sh
sudo cp /usr/local/bin/jamulus_start.sh{,.bak}
