Hi all,
I am asking here because over the years I have not found
convincing/detailed information in google about:
Which audio adapter do you use to use a 2ndary sound card in jack?
1.jacl_load audioadapter
2. alsa_[in | out] ?
3. zita_[a2j | j2a] ?
why do you use the one you use? What are its advantages ? Have you
identified or do you know of any disadvantages for each of the above ?
Do you have preferred options to minimize xruns ?
Thank you in advance for your help

This subject seems to come up occasionally...
What is the current best practice with regard to Jack classic versus
Jack 2? It's usually said that Jack 2 is optimized for SMP, but it's
hard to find a machine these days that isn't SMP. Maybe the two
projects are merging because of this?
Because, Jack 1 hasn't gone away. In fact, the only version of
jack-audio-connection-kit currently in Gentoo (no overlay) has a version
string of 0.125.0-r1, and I presume that's Jack 1. I've got a local
overlay with 1.9.12 that I've been using, so I can fight this of
course...but should I? Is everyone being advised to move to Jack 1 now?
For what it's worth in deciding, I prefer not to use dbus for control
(or for anything at all, when I can avoid it), and I'm using QJackCtl as
a frontend.
Hi all,
For the purposes of this discussion, I am playing guitar through an Axe-Fx
II into a Behringer UMC1820 USB rack soundcard. OS is Xubuntu Focal 20.04.
This works fine for general jamming, I can play a backing track from the
computer and use the hardware monitoring to mix in the Axe-Fx as necessary.
But when I want to record, the levels are low. I record using my Android
phone, and activate Audacity to record the guitar tracks from the Axe-Fx.
But the levels are so low, the waveform is tiny. I can apply a plugin to
increase the volume, but you can imagine the quality.
I see the same thing in the Pulseaudio Volume Control Input Devices tab, so
it's not an Audacity issue. With jackd active, the input levels are fine, I
can see them in Ardour. But I don't want to have to activate jack for more
simple stuff like this, it's a pain.
For what it's worth, the output level of the Axe-Fx is around 75%, and the
input gain knobs on the soundcard at about 25%. Any higher and the clip
lights come on when I play hard.
Any clues on how to debug / fix this? I'm suspecting a driver issue,
because there simply aren't that many moving parts.

Hello, Listers--
I've successfully mapped two of my MIDI knobs to the filter's cutoff
frequency controllers in both SubSynth and PadSynth. The problem is that
in neither of these engines does the sound change continuously. The
controller on the GUI moves when I twist the mapped MIDI knob, but I need
to strike the key, again, to hear how the sound has changed. Apparently,
filter sweeps are not allowed in either of these engines? This is not a
problem in AddSynth.
Some further details:
OS: Ubuntu Studio 18.04, LTS
Yoshimi: 1.7.4
Controller: Akai MPK88
Have I missed something? I will continue to search the manuals, lists, and
other docs.
Thank you!

Hi,
Does anyone use Calf FluidSynth?
I have used it for ages now with my home-grown midi sequencer, but have
noticed
odd behaviour just lately.
This is to do with sending Program Change events. My sequence (and the
MIDI protocol)
expect channels to be numbered 0 - 15, though most programs and physical
devices tend
to refer to these as 1 - 16. That's not a problem for me. What is a
problem is Fluidsynth
now seems to be treating 0 - 15 as 2 - 17?
I'm trying to sort out a midi file for a friend - generated by a Windows
Package - and
the file has 4 tracks (not counting track 0) for Violinx3, Viola and
Cello. The midifile
treats these as channels 0 - 3, at least initially. However, Fluidsynth,
which always
starts up with Piano for all channels (except 10) sets channels 2,3,4
and 5 to these
devices. I've got a program to monitor the midi events sent over Jack
and this convinces
me that the Program Change events are specifying the right channels, so
I can only assume
that Fluidsynth is mapping 0 - 3 onto 2 - 5, which sounds like a bug.
As it happens it turns out that when the midifile want to witch to
pizzicato, it switches
to channels 4-7 (5-8 in user terms) but hasn't specified a program for
those channels!
I found the Calf website not very helpful about fluidsynth, and I don't
really want to get
signed up to another email list to discuss bugs in fluidsynth. Just
wondered if anyone
on this list had come across this.

I thought a while back I found a good compander plugin.
Then didn't use it for a loooong time.
Now can't remember or even find one.
For some reason I thought it was Calf offering...
Any help for an addled old brain?
Thanks
Hey David!
Thank you for your comments!
"I listened to Droning 300 today and the instruments sounded just like the
ones my friend uses in his FL Studio songs."
You mean "Healing Fountain"? Healing Fountain is all DSP and samples that I
created myself. There is a glissando that uses some sort of marimba, but
even the "laser" sound is the sound that I created myself from scratch
using 3xOSC synth.
In general, if you avoid using exactly the same presets, I think it's very
difficult to gauge what you use to create music. If you would go back to my
droning project, I doubt that in most cases you can tell when I used FL
Studio and when I used my Linux Audio setup.
"getting good sound and high quality mixing required tools that are simply
unavailable on Linux today.
Really?"
Unfortunately.
I think I won't make a claim that it is totally impossible, but it's
definitely not trivial. I have produced hundreds of tunes with Linux Audio
and explored loads of tools during that time, but I couldn't even find an
EQ that would work well for me. There is one EQ product that seems ok, but
for me it was unstable and kept crashing my projects.
Additionally, high quality plugins matter, just like high quality equipment
matters. I was using ZynReverb while on Linux and it created all sorts of
problems for me. The quality of my mixes has changed dramatically when I
switched to Valhalla, because it's reverb made by a company that put a
decade into perfecting it. They made sure, for example, that it would
produce a smoother sound, heal resonating frequencies, etc. They have a
description of this on their website and a YouTube channel too.

Hey hey,
I just released the numbers sample pack:
http://juliencoder.de/sound/numbers-1.0.zip
It contains the numbers 0 to 20 in both English and German as well as some
other calculator related words like minus, integral, function, logarithm, etc.
The samples were made with espeak-ng and a modified voice variant. The pack
also contains two scripts to create the numbers 0 to 20 in every language that
is available for both espeak-ng and Apple's say.
The samples are CC-BY 4.0. Have fun and create some calculator beats. :)
Best wishes,
Jeanette
