Help: Problem receiving midi in Run on boot mode

tkay

Hello I'm running a pure data patch that uses a (class compliant) midi keyboard input via the USB port. When I run the patch in the IDE everything works fine. But when it runs on boot it doesn't receive the midi data. Otherwise the patch runs fine in run on boot mode, it's just the midi that is not working. When the patch first loads on boot in the IDE I see a message says No MIDI device enabled. Once I click the build and Run button on the exact same patch it shows "The following Midi devices are enabled 0 hw: 1, 0, 0 x (1-16)" I tried using an externally powered USB hub and another controller that has its own power and got the same results. I also tried other patches including the hello midi example patch and exact same results. I also tried sending a loadbang hw 1 0 0 message to the bela_setMidi but and got the following messages:
Failed call to __wrap_bind: 17 File exists
Error while creating pipe bela-midiOut_hw:1,0,0: Operation not permitted
Any ideas?

it's a known bug which will be fixed in the next release of the Bela image. In the meantime, do the following:

In the console at the bottom of the IDE paste this line and hit enter:

printf "libcomposite\nrtdm_pruss_irq\nsnd_usb_audio\nsnd_usbmidi_lib\nspi_gpio\n" > /etc/modules

reboot and it should work fine

Ok great, it fixed it. Thanks so much. Will be sure to update when it comes out. Should I do that every time I load a new patch?

no, it's done once for all: it's a system-level change.
