Arena, Midi Buttons are triggering next column two times

[VJ_Autopilot]

Hello,

I mapped a Midi button to the next column button in Arena.
In general it works, but from time to time the midi buttons are triggering next column two times. I would estimate, that every 50th click is doubled. This happens on two different midi devices.

My system is :
Latest Arena, Win 10, Devices: faderfox UC4 and a AKAI apc40
Midi Input and Midi output activated. Mapping mode is absolute.

Perhaps someone has a hint to avoid this.
With computer keyboard everything works as expected.
Its not a good option in my case, because i have to use other progams at the same time.

Best,
autopilot

Can you leave the Preferences - Midi inspector open and see if you get duplicate midi input?
It's the small play button on the top right.
