Regarding the last point: I find that using the right/left arrow buttons almost always causes sfizz to crash! Previously I was usng the lv2 version of sfizz; I have now tried the vst3 version, but with similar results.
So I decided to try to install the latest git version of sfizz, using your very helpful step-by-step instructions. Unfortunately the first cmake command produces this error:
Package 'jack', required by 'virtual:world', not found
I certainly have the jack server running on my computer, and QjackCtl shows it to be working OK. No package called simply 'jack' seems to exist in the regular Ubuntu Studio repositories, so I'm not sure what to do about it. Any suggestions?

I mentioned in a previous email that I've switched to Pipewire on my laptop.
It works fine with most things - I use Audacious to play CDs, and
Firefox seems
happy enough to play things from You-Tube or BBC. However, when I try to run
GrandOrgue I get confusing messages, saying:
Error: No sound output will happen. Samples per buffer has been changed
by the sound driver to 512.
Under jack, I had been running at 44100sps, with 2 buffers of 1024 samples.
QJackCtl shows this as still being in force, though whether this is what
pipewire is
actually doing I don't know. Changing setting in QJackCtl to 512 spb
gives a message
which suggests that pipewire is still expecting 1024.

Hi,
I'm putting together a digital organ using GrandOrgue and Jack, I've had
to adapt
a program called ttymidi to convert serial input from Arduino scanners
to Jack which
passes it on to GrandOrgue. It all works fine until I try to polish up
the pwoer-on
sequence. If I start the modified ttymidi code before jack has got going
it falls
over. I want to be able to test out my modified code on my laptop, as I
only get
access to the organ occasionally. Unfortunately I recently switched my
laptop to
use pipewire instead of pulseaudio (for general usage, such as watching
web videos).
That got sorted out, but when I came to testing my code, it seems to set
up the
connection to jack even when I've stopped jack (actually jackdbus). Is
this because
pipewire is intercepting the requests (jack_open_client(...))? I tried
adding an
input port, and this seems to connect OK, and the client appears on
qjackctl's
connection graph, despite qjackctl saying that jack is stopped! Is
pipewire doing
a complete replacement for jack? I can't find much on the web other than
initial
install and setup, not much about how it works. I can probably sort out the
above problem next time I can access the organ, which doesn't need
pipewire or
pulseaudio, so it will just be running jack, but I am curious to know
more about
what is going on. Anyone on this list actually part of the pipewire team?

Just read about this:
https://github.com/bitwig/dawproject
As with many of these 'standardization' efforts success might depend
on adoption, but it's an interesting initiative, so we will see what
happens :-)

Anklang version 0.2.0 is released.
Anklang is a digital audio synthesis application for live
creation and composition of music. It is released as Free
Software (MPL-2.0) and runs under Linux.
The real-time sound engine is implemented in C++, the UI runs
in Electronjs, Firefox or Chrome. Assistance with development,
porting or creative efforts is very welcome.
Anklang provides a MIDI sequencer, Undo/Redo capabilities for note
editing, real-time synthesis, and support for CLAP plugins.
The source code and binary packages are available here:
https://github.com/tim-janik/anklang/releases/tag/v0.2.0
The project website with further resources is at:
https://anklang.testbit.eu/
=======================================================================
This release has significant improvements to audio synthesis
capabilities and user interface. The documentation has been improved in
several places, and automated generation was integrated into the CI.
Audio synthesis enhancements include support for new CLAP (draft)
extensions, such as transport information and file references. We now
support non-linear mappings for BlepSynth ADSR times, and a new audio
plugin Freeverb by Jezar at Dreampoint was added, with fixes to the
damping mode in the original version. Additionally, a Jack PCM driver
based on Stefan Westerfelds’ code was integrated.
Performance improvements were achieved by adding a new optimizing memory
allocator and supporting low-latency scheduling via sched_* or RtKit.
Saving projects will now automatically create backups of recent versions.
The user interface has also seen significant improvements in this
release. These include context help via F1 key in various UI components,
fixes to mouse wheel sensitivity for modern browsers, improved tooltips
and note editing in the piano roll. The UI can now be zoomed via new
menu entries, the color palette was updated, and integration of
TypeScript annotations allowed improving the UI JavaScript code quality.
In terms of packaging, AppImage builds saw major compatibility
improvements, and we increased the frequency of Nightly releases,
building from nearly all significant trunk merge commits. We aim to
generate more regular releases in the future instead of having lots of
Nightly builds between regular releases.

Thanks for that suggestion. Â I confess that I didn't even know that
Carla could be run stand-alone.
I tried this, but unfortunately I still get a crash every time I edit
the sfz file. Â I might perhaps try installing the latest git version of
sfizz.
But in the mean time, I find that the simplest solution is to call my
file something like filenameA.sfz, then after making an edit I save it
as filenameB.sfz, after another edit filenameA.sfz. and so on. Â I
simply have to load the latest version as a new file in the sfizz
plugin, and by alternating the 2 filenames I avoid the crashes.
David
I'm pretty new to using sfz, and have been experimenting with modifying
files.
I'm running Ubuntu Studio  23.04, and I have sfizz as a plugin to a
track in qTractor. Â I have also tried using Carla-rack as a plugin,
with sfizz inside that.
Unfortunately in both cases, if I make an edit to the sfz file I am
testing, qTractor crashes. Â I don't know whether the problem is with
sfizz or with qTractor itself.
Sforzando appears to reload a file if it is changed, so that you can
immediately test out the results of your edits. Â Unfortunately of
course, Sforzando doesn't exist in a Linux version. Â I know some people
have got Sforzando working in Wine, but I'm not at all clear about how
to do that or whether I could then use it inside qTractor.
Is there some way of being able to test sfz files, with automatic
reload as in Sforzando, but using native Linux programs and/or plugins?
Hi list,
for anyone wondering why qjackctl 0.9.9-1 on Debain stable (bookworm)
does no longer display its icon in the systray after starting: The
package libqt6svg6 is required but sadly not a dependecy of the qjackctl
package.
Rui, thank you for your amazing work, using your tools for more than a
decade now!
best, Peter
