Unable to aconnect to a USB Midi keyboard

Postby turgu1 » 2019-06-04 00:24

Hello all,

I'm trying to use both a Roland HP piano and a Roland A88 midi controller using a USB connection. The os is Debian with kernel 4.9

In a nutshell:

The midi keyboard is connected to the computer (odroid-n2 sbc);
The command 'lsusb' shows the device
The command 'amidi -l' shows the device
I can see the device special file /dev/midi1
I can see the midi keyboard output using 'cat </dev/midi1'
BUT, the command 'aconnect -i' doesn't show the device

The aconnect is important to work such that the device could be selected in software by the user.

The loaded sound modules are the following (part of the lsmod command):

snd_seq_dummy 16384 0
snd_usb_audio 192512 0
snd_hwdep 20480 1 snd_usb_audio
snd_usbmidi_lib 32768 1 snd_usb_audio
snd_seq_midi 16384 0
snd_seq_midi_event 16384 1 snd_seq_midi
snd_seq 73728 3 snd_seq_midi_event,snd_seq_dummy,snd_seq_midi
snd_seq_device 16384 2 snd_seq,snd_seq_midi

The snd_rawmidi module as been compiled inside the kernel image.

Any idea how I can find the problem?
