Mixbus 6 some issues and observations

[wavesound]

Hi All
Further to a few posts on here,
I get a disconnection sound each time I stop the track, sounds quite bad, This is when the X runs increase. I can get between 2 and 4 Xruns per disconnection.
The scissor thing is still causing MB6 to quit without warning.

Which clock is Jack using for reference? the pc or the X32? This does sound like a timing issue.

Hi
I decided to take a look under the hood, always a bad idea for a musician!!
In case you don't have it Studio 19 has a thing called Audio controls, this controls jack and all sound cards.
I fired up Qjackctl and found it was set to 44k and 3 buffers !!
So MB6 is running in 48k as it should but jack was seeing 44k!
So something is amiss with the Audio control in Ubuntu studio.

Will be spending the rest of the day on these new settings and will let you know.
Cheers All

For what it's worth took a bit of starting getting Carla to see the X32 after this.

In general, you should use the 44.1K clock rate. There are many good explanations
of the differences and target use of 44.1k / 48k out on the internet. Check them out.

Regarding buffers... 3??? Mine, and my recommendation, is: 1024.
Too few buffers and you run the risk of buffer overflow and lots of crap results.

I guess 1024 is the size in bytes of each buffer.
I've read somewhere that external USB audio interfaces worked best with 3 buffers instead of 2.

Hi Thanks for this yes I read about the 3 buffers for USB Just finished a four hour session and have 170 X Runs!! but no clicks I can hear at the moment.
Thanks for your help all.

Hi I have always used 48K as this is what MB6 and ardour use natively

And 512 or 1024 as mentioned. Please note I monitor from the X32 in real time.

Hi All
Been noting a few stability issues with Ubuntu studio 19.10.
Yesterday 10 hour session all fine.
Today 1 hour into a new session went to rename a track, complete lockup and had to power cycle the pc. Not had to do that for years.
My Feeling is that studio 19.10 is not quite stable re jack and the audio controls.

Just a heads up.
Cheers Bob

Hi All
Still getting MB6 quitting using the scissors, on Stdio 19.10, becoming a real pain.

Hi All
Another hard reset re power button as of now I would give Ubuntu studio 19.10 a miss on a production system.

I'll be going back to studio 18* and MB6.

Cheers All

Try - AVLinux, ver 20.04 -
I just upgrade to that from my previous AVLinux release (2 years older).
Mixbus 32C ver 6 (I'm running 6.0.702 & MB ver 6 both have been stable for me.

Cheers!

HI
Not used AV linux at all I'll give it a try just waiting on a PCI ssd arriving so that will take some setting up.
Worth a go
Thanks for your help.
