Time will tell.
I will continue testing with the next release and keep you informed.

Testing with 5.4.2 which doesn't have any problems, CPU usage is the same like 5.5 and 5.6.
I will continue testing, maybe I will find a hint where the problem is coming from.

Thanks you so much for your support.

Specs:
Processor i5-6300HQ CPU @ 2.30GHz (quad)
Installed RAM 8,00 GB

Changing refresh rate of VU and Display to 0 doesn't make a difference.

Testing 5.6.2, different devices or output doesn't make a difference.
JP cpu consumption surprisingly high.

Will JP remember the midi port when i start it again?

Wow, that is it!
Thank you so much!

I did change the channel in the channel MIDI Hardware output routing.
Thanks for the hint, never thought about changing it at the input side.
Sorry Win10 is hiding the routing window when I am trying to screenshot.
Your updated MIDIOut.exe is also working without any issues.

Didn't try the tool on OBS yet because it's running on another PC and takes more time for setup,
but I did integrate it in Reaper, works like a charm!
The only thing missing is a choice for the midi channel although I can change it in Reaper too.

I would be well satisfied for having midi out for just the jingle buttons.

It happens randomly, no specific timing and length.
After switching between different versions of JP I now get the impression that the problem does not happen so often anymore.
After pressing about 40 times the problem occured again and I did capture the audio.
Where can I send it to you?
