Uhhhh! Nice!! Try now …
I got it working with one machine. But the second one doesn’t…i investigate…
The machine, that is not working has an old image (???).
I will create a new image for this machine tomorrow.
And it uses MCP23008
So maybe the wiring like this is the issue

Maybe you stop at the first 0 GPIO somewhere…

I installed 2020-03-11+update and still don’t get the snapshot loaded on the MCP23008 with no zyncoders but 3 custom switches.
If you can’t reproduce this scenario. Could you tell me, where I should add logs?
Send your wiring config
It seems good. If the switch works as CUIA, i don’t see any reason for not working as MIDI action. Look for the “MIDI SWITCHES SETUP…” in the UI log.

Mar 13 22:45:36 zynthian startx[15321]: INFO:zynthian_gui: MIDI ZYNSWITCH 7: 12 CH#15, 1
and when I press

It looks fine! Try with a channel different from Master and disable the ZS3. You should see the MIDI event in the MIDI log …
Regards,
no midi messages (no blue m in ui neither)
And does it work with Note or CC messages?
no note either. I didn’t test CC
OK! I have it! MIDI send wasn’t implemented in the old zyncoder MCP23008 code (polling zynswitches).
I just created a branch in the zyncoder repository:
zynswitch_poll_midi
Please, test with this branch!
cd /zynthian/zyncoder
git fetch
git checkout zynswitch_poll_midi
git pull
./build.sh
systemctl restart zynthian
Regards,
Great…note works…testing pc now

yes, pc as well. and 0 is the first one…like expected. although you could define 0 to load the default…

It’s merged on master now

Hi, I added an extra switch to the pin 16 (GPIO23/wPI4) of the RPi4 and I can detect it working from the commandline, but I cannot make zynthian detect it. I tried adding both 4 and 23 to the end of the list of switches in the webconf, but nothing works. Not a single message in the UI log either. Standard buttons on the MCP work well.
Am I missing something? I have to admit that I am not sure about the exact role of the “Wiring Layout” selector. So I have just selected the “Mcp23017 Zynscreen” option. Do I need to switch to another one?

Sorry @wanthalf , the current zyncoder code has come limitations and doesn’t allow to mix switches on the RBPi GPIO and MCP2317.
Oh!.. Is it a temporary issue or all the guides about wiring buttons to the RPi just automatically expect that you do not use any MCP at all? Why is there talk about “extra” switches, then - “extra” to what?
Well, I have not studied the code, so I do not know whether you use some python library or just bash scripts, but that should not be a big problem, is it? When seeing the numbers above 100, I just expected a system similar to the IoAbstraction library for Arduinos - but OK, this is a completely different platform, so I should not be surprised and let me confuse by the similar system of PIN numbering.
I see now - the zyncoder module is written in C using the wiringPi library. I will try to have a look at the code, why is it a problem to deal with both an MCP and native GPIO at the same time… I already noticed that multiple MCPs are not supported either (yet?).
