Disable Keystep Transport

Using Zynthian
1

I’m using a Arturia Keystep with Zynthian and am finding that whenever I press the transport buttons they send SYS messages that are causing the MIDI Recorder to start playing. I tried disabling the transport buttons from sending messages via the Arturia Control center, but they still get sent unfortunately.

Whenever I press stop, the Zynthian UI displays: ‘NoneType’ object has no attribute ‘pid’

It would be nice if I could set a MIDI rule to ignore SYS messages, but I couldn’t find any way to do that.

Any ideas how I could disable these? Thanks!

That’s familiar . . .

What does the MIDI log (and GUI debug) on the webconf say while all this is going on…?

Hey,

I just started using my Keystep with the Zynth and am getting the same issue.
The Keystep has an on board sequencer and arp and pressing play/stop controls this.

Also, rather weirdly, pressing play triggers a saved MIDI capture.

The MIDI log reads as follows

CH#01 CONTROL_CHANGE 54 => 127

SYS START

SYS CLOCK

SYS CLOCK

SYS CLOCK

SYS CLOCK

SYS CLOCK

SYS CLOCK

CH#01 CONTROL_CHANGE 54 => 0

SYS CLOCK…(repeats until I press stop)

…
…

CH#01 CONTROL_CHANGE 51 => 127

SYS STOP

I tried the MIDI filter to ignore 54 and 51 but that did nothing, so i’m guessing its the SYS messages.
I also get the “‘ERROR Stopping MIDI Play - NoneType’ object has no attribute ‘pid” on pressing stop.

Any thoughts?

Hi @Simon and @Quixotic7!

I just added an option to disable the MIDI System Messages. Simply update your zynthian and the option will appear on UI’s Admin or Webconf’s MIDI options.

Enjoy!

Having just updated to the buster Image ( 2020-02-28)
Un-checking this option in the webconfig and then save, does not apply the setting and the box re-ticks.
It works on the Zynthian though.
