Sunvox on Riotboard Linux : MIDI questions

Post by stevie232323 » Thu Feb 22, 2018 3:27 pm

Привет, красивые люди!!

Hi guys. Now I have Sunvox working on Riotboard running Linux Ubuntu I am trying to get a couple of things working, one of them being MIDI.
I have a USB to MIDI cable (cheap chinese job, works fine) that I have plugged into one of the Riotboards' 4 USB ports. I know Riotboard sees the USB cable because I can send MIDI bytes to it using Terminal and the aMIDI command. It also shows up as USB MIDI USB 1.
However, when I open Sunvox and navigate to the MIDI prefs, I don't see it in the MIDI connections. All I get is MIDI connections : none.
I have tried setting channels to any but still no avail...
Any help or is it possible?
Thanks again.
STeve. S :)

MIDI output settings are not in the SunVox preferences. It is in the module properties (double click on the module).

Hi Nightradio. Thanks 4 replying.
well...
I tried what you suggested. Clicked on the module (in this case a simple generator) and I still don't see an option for my MIDI USB. All I see is MIDI OUT: none. :(
What could be the problem?
Like I said, the rRiotboard sees the USB MIDI adaptor and AMIDI sends bytes to it but no joy with Sunvox....

Yes and i don't know why :( ALSA can't open MIDI sequencer device for some reason...
Please show me the output of the following commands:

Code: Select all

aconnect -i
aseqdump

I'm not sure... :(
Seems that something wrong with ALSA on the Linux kernel level...

Yeah. It looks like the Kernel for this version was compiled without it.

Какой облом!

Oh well I guess I'll just have to figure out how to recompile a Kernel with the snd-seq module and activate it!!
Something I know nothing about but It'll be worth it for Sunvox. 8)
