Re: Ultralite AVB

I have a MOTU 1248 and have the same issues since the TouchControl firmware update. I wonder if it's related to the addition of the "host offset" buffer setting. I agree that it's probably an ALSA or PulseAudio problem because it also happens in "plain" distros like Ubuntu, Manjaro, and Neon that a...

Re: Ultralite AVB

I posted the problem on the alsa-devel mailing list. I want to get the issue fixed. The Ultralite AVB is such a cool interface.

Re: [Motu M2] [Linux] Equalization

Thanks. Is there such a thing as an audio interface that performs the equalization instead of the computer's CPU? Is this (or could this be) one of several reasons for a DSP existing in an audio interface? If you need only 2 channels, for example to EQ your active speakers, then I recommend the rea...

Seems to work fine for now, but channel hopping is still a problem
I am not sure if the channelhopping is an ALSA or a jackd problem. Since restarting jackd helps, it may be a jackd problem. Unfortunately I got no helpful response from the jackd mailing list.

The trouble is ; that the only active code in that config is
### Automatically connect sink and source if JACK server is present
.ifexists module-jackdbus-detect.so
.nofail
load-module module-jackdbus-detect channels=2
.fail
.endif
I'd try to comment out that stuff.

Re: Ultralite AVB

At least the sound quality is ok while running jackd for more than 10 hours.

Re: Disable pulseaudio Jack source but keep Sink running.

You might remove jack-source from /etc/pulse/default.pa

But I guess it's not there but loadeddynamically by some tools that you run.

You could use pavucontrol to mute jack source in Pulseaudio.

Re: Ultralite AVB

No big improvement: When I change the buffer size with jack_bufsize I get a modulo-8 output channel hop.

Re: Ultralite AVB

OK, the patch could be simplified and on my machine I get some sound out of the Ultralite AVB. It's the older one without ESS chips but with the most recent firmware.

The patch is for linux-5.8-rc6.

Test && enjoy.

Re: Ultralite AVB

I am no great programmer but I see that linux-5.8-rc6 has added support for implicit feedback.

I try to adapt drumfix's patches to that kernel to see if there is some improvement, but don't count on me.

PulseEffects runs on your computer and uses your computer's CPU to calculate all of its effects.

Re: [SOLVED] MIDI sound quality issue

Can't you simply connect all of them to your DAW, e.g. with Qjackctl and record/play a single track with that data?

Re: MIDI sound quality issue

My M-AUDIO CODE61 has several MIDI"channels" that can be connected:

Maybe your Korg has them, too, and you have to connect all of them to your DAW to get the modulation data.
