Issue with OPi0 RT kernel+midi

[rodig0]

Hi , there

I have RT kernel on my OrangePi Zero now.    

Linux orangepizero 4.14.8-rt9-sunxi #1 SMP PREEMPT RT Sat Jan 6 14:36:31 CET 2018 armv7l armv7l armv7l GNU/Linux

 

Guru, please, HELP me to reconfigure it to using MIDI + Pure Data!!!

ALSA is fully installed. But there's a problem:

 

root@orangepizero:~# aconnect -i
ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
can't open sequencer

 

Thank in advance.

You need to recompile kernel with enabled https://github.com/armbian/build/blob/master/config/kernel/linux-sunxi-next.config#L4237 and CONFIG_SND_SEQ_MIDI below this.
