Newbie question: saving & recalling qjackctl patch connections

eccn
Hi there

I want to automatically patch all my MIDI and digital audio
sources/destinations, every time I use my regular sound applications.
These include Rosegarden, Ardour, Jamin, ZynAddSubFX and Audacity.

I think the apps can sometimes assert their own jack connections, so I
expect I also need to set options in each app.

Is there a help file about this facility anywhere please?

Thanks & regards,

Matt Rhys-Roberts

The Patchbay window in QjackCtl can achieve most of what you need.
Audacity is slightly problematic in this regard because it does not have
JACK port persistence (i.e. ports are only created once you hit the
play/record buttons, at least in the build I use).

Not really, most JACK applications will follow the settings that the JACK
server demands. One exception is ZynAddSubFX, which defaults to 44100Hz
sample rate; not that it seems to make any difference when using JACK.

Cheers!

Daniel

Thanks for the advice

How can I save JACK patch connection settings, if at all?

Matt

It's easy - in the Patchbay window of QjackCtl, just click New to
snapshot the current settings, then click Save and choose a filename.

Cheers!

Thanks Daniel

That should do the trick. I'd incorrectly dismissed the Patchbay window
as a strange, alternative version of the Connect window!

I promise to RTFM next time

Best regards & happy sonic breakthroughs,

Matt
