Help: Problem receiving midi in Run on boot mode
5 days later
New image out that fixes this issue https://github.com/BelaPlatform/bela-image-builder/releases/ (v0.3.8b and above)
3 months later
I reflashed my bela to this new image but now I don't get any midi input even on the IDE...by default it says No MIDI device enabled...Any ideas off the top of your head?
Thanks,
Tom
tkay I reflashed my bela to this new image but now I don't get any midi input even on the IDE...by default it says No MIDI device enabled...Any ideas off the top of your head?
Does this happen only when running the project at boot or also during regular operation?
Can you run amidi -l in the console at the bottom of the IDE and report its result?
it doesn't receive any midi either on boot or on the ide
so the device is not showing up (hw:0,0 is the virtual interface over USB between Bela and yout computer)
What about lsusb -l ?
What MIDI device is connected? Does it require external power? Does it have any LEDs on it showing that it's receiving power?
Its a cheap usb powered keyboard...But it worked fine before. I also tried a powered nord keyboard and same thing happened...
it does have LED and it shows as being powered
- Edited
it says invalid option ...if I use the v function it says this:

tkay it says invalid option ...if I use the v function it says this:
sorry it would have been just lsusb (without options), could you please try again?
Can you also show the output of:
lsmod?
Then:
- unplug the MIDI device
- wait 5 seconds
- plug in the MIDI device
- run dmesg | tail -n 20 and show the output of this command
In all this, can you try a different USB cable for the device and verify whether that is the issue? Some cables only carry power and not carry data. Some socket connectors may also prevent the plug from being fully inserted, obtaining a similar result (only power, no data) [which is - by the way - what happened to me a minute ago].
Thanks for such quick responses
lsubs threw this at me:

I also tried 2 different cables
really weird ... can you try the Nord keyboard again and lsusb and amidi -l ?
ok will do and report back tomorrow, have to leave the studio now...I should mention that I also ran the first script that you gave me before the new image came out...
So I plugged in the same keyboard today and magically it worked...I guess it must be a loose connection on the usb?
It could be ... it's a mystery! Maybe check the inside of the USB socket (and plug) for any detritus? although that'd have to be pretty big to cause electrical continuity issues!
a year later
I will add to this that I frequently have the USB MIDI fail to work on boot up, maybe one time out of ten, randomly it seems.
What image are you running ? This was definitely pathologic on some image versions (v0.3.8 through 0.3.8b), but it should be fixed now.
