Hi, I wanted to try the Single Channel Mode, but it doesn’t seem to work: Zynthian hangs if I try setting it in the admin menu, while if I try it via the web config I get an ‘500: Internal Server Error’ message. Zynthian is updated to the latest version.
Harm
update the machine and try again
Hi MHeidt,
I’ve updated Zynthian, but Single Channel Mode is still not working.
I tried two different setups: one with an IQAudio DigiAmp+ and a Edirol (Roland) UM-2X usb midi interface and one with a Steinberg UR22 mkII usb audio/midi interface. It doesn’t work on both Zynthians.
Harm
It works for me. What do you expect, it would do?
Have you checked the Midi Out Settings in the webconf as well? Maybe something is deactivated
I expect it to turn on (checked in the admin menu) if I select this option - instead it freezes the UI, or if I set it in the web config and press save I get a 500 error.
I guess, you don’t have the latest version installed or it is corrupt. Try to get log messages.
Maybe it’s the same problem like the one in that other conversation here.
But I can’t reproduce it.
Hello @Harm and @mheidt,
I got the same problem that after choosing Single Channel Mode the Zynthian symbol is moving on and on…
I got the following if I start my zynthian via
/zynthian/zynthian-sys/sbin/zynthian.sh

I hope this might help tracing what’s wrong…
I wish you a nice evening and God bless you, Marius
ok, the issue only occurs, if the midi profile file doesn’t contain all variables.
Hence deleting the default profile would have helped.
I fixed it now, so that a new update should solve it as well.
@mheidt, I updated Zyntian (the usb audio set-up), but now it doesn’t start the UI anymore. This is what I get from zynthian.sh:
(EE)
Fatal server error:
(EE) Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.
(EE)
(EE)
Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
(EE)
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server “:0”
after 7 requests (7 known processed) with 0 events remaining.
try again. I only get this, when the process is still running.
of when I have a serious config issue
Hello Markus @mheidt,
for me it is working now…thank you very well for fixing it.
I hope it is solved for others as well!
But I have an issue with jalv and obxd.
In which forum section shall I post it? Software or using Zynthian?
Thanks and God bless, Marius
I would use Software
@mheidt, I updated again (and adjusted /etc/dbus-1/system-local.conf agian), and it still doesn’t boot up, however if I first stop Zynthian and then start it using /zynthian/zynthian-sys/sbin/zynthian.sh, it does work. If I reboot again it doesn’t. This is the output of zynthian.sh:

what is your soundcard?
I had that issue when I made my first AudioInjector Ultra tests. I had to run 48k, but why do you?
Behringer?
@Baggypants might help
I’m using the Steinberg UR22 mkII (capably of 192kHz - but that seems an overkill for Zynthian).
I found the issue: after the last update the sound card is all of a sudden recognised as hw:0 instead of hw:1. I changed it in the jackd options and now it works again.
