Hello all,
I'm trying to use both a Roland A88 midi controller (Keyboard) using a
USB connection. The os is ArchLinux with kernel 4.9
In a nutshell:
The midi keyboard is connected to the computer (odroid-n2 sbc);
The command 'lsusb' shows the device (3rd line):
# lsusb
Bus 002 Device 002: ID 05e3:0620 Genesys Logic, Inc.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0582:0157 Roland Corp.
Bus 001 Device 003: ID 148f:5370 Ralink Technology, Corp. RT5370
Wireless Adapter
Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
The command 'amidi -l' shows the device
# amidi -l
Dir Device Name
IO hw:1,0,0 A-Series Keyboard MIDI 1
O hw:1,0,1 A-Series Keyboard MIDI 2
I can see the device special files /dev/snd/midiC1D0 and /dev/snd/seq
I can see the midi keyboard output using 'cat </dev/snd/midiC1D0'
BUT, the command 'aconnect -i' doesn't show the device:
# aconnect -i
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
The aconnect is important to work such that the device could be selected
in software by the user.
The snd_rawmidi module as been compiled inside the kernel image.
Any idea how I can solve the problem?
Thanks!
Guy
