Hello list, I recently tried out petri-foo and I like it enough to care about it in the form of bug reports. I don't know how to contact the developers though. The website http://petri-foo.sourceforge.net/ says last release 2012, the github repository is switched to read-only. Did I miss the active development place somehow? Fork of a fork? -hgn

[ANN] caps-0.9.24

by Tim Goetze

http://quitte.de/dsp/caps.html The latest release of the caps audio plugin suite contains a number of bug fixes and improvements as well as changes intended to make it more suitable for low-power systems. http://quitte.de/dsp/caps.html#CHANGES Most notably, support for a variety of little-used features has been dropped, reducing the binary size by roughly a third. There's also a new plugin implementing simplistic linear emulation of several guitar amplifier loudspeaker cabinets with reduced computational complexity: http://quitte.de/dsp/caps.html#CabinetIII The compressor plugins now report current gain reduction: http://quitte.de/dsp/caps.html#Compress http://quitte.de/dsp/caps_0.9.24.tar.bz2 Cheers, Tim

Don't know how well VSTGUI works on linux though. Using gtkmm as the underlying GUI to implement VSTGUI on top of seems worrying.

New(ish) OSS synth plugin

by Daniel Swärd

Hi all. Just found out that one of the Bitwig devs has released an older (commercial) project of his as open source: https://github.com/kurasu/surge Doesn't yet build on Linux, but quoting from the github page: "It currently only builds on windows, but getting it to build on macOS again & Linux should be doable with moderate effort." How about we get it building at the next Berlin LAU meeting? Cheers /Daniel

Yoshimi V 1.5.9

by Will Godfrey

Apart from the new list of helpers, there is little visible change for most users, but the command line has now been greatly extended. Full details are in doc/Yoshimi_1.5.9_features.txt Also, there have been significant changes in the underlying code. These were always planned, but maybe not reported and explained as well as they could have been. More info is in dev_notes/Selection_Structure.txt -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

by Rui Nuno Capela

That's it! QjackCtl 0.5.4 (early-autumn'18) is out! QjackCtl [1] is a(n ageing but still modern, maybe not so 'simple' anymore) Qt [2] application to control the JACK [3] sound server, for the Linux Audio [5] infrastructure. Website: https://qjackctl.sourceforge.io http://qjackctl.sourceforge.net Project page: http://sourceforge.net/projects/qjackctl Downloads: http://sourceforge.net/projects/qjackctl/files - source tarball: http://download.sf.net/qjackctl/qjackctl-0.5.4.tar.gz - source package (openSUSE Tumbleweed): http://download.sf.net/qjackctl/qjackctl-0.5.4-33.rncbc.suse.src.rpm - binary package (openSUSE Tumbleweed): http://download.sf.net/qjackctl/qjackctl-0.5.4-33.rncbc.suse.x86_64.rpm - AppImage [7] package: http://download.sf.net/qjackctl/qjackctl-0.5.4-5.x86_64.AppImage Git repos: https://git.code.sf.net/p/qjackctl/code https://github.com/rncbc/qjackctl.git https://gitlab.com/rncbc/qjackctl.git https://bitbucket.com/rncbc/qjackctl.git Change-log: - Graph port-type colors are now configurable (cf. menu View > Colors. - Make Graph nodes (ie. client boxes) transparent for yet some eye-candiness ;). Also keep the (Graph) current selection across port (dis)connections. - Drawing patchbay connector lines as (bezier) curves is now a difinitive and fixed feature (as long as no moreremains from the so called "Cambric explosion era" are still lurking in there). - AppStream metadata updated to be the most compliant with latest freedesktop.org specification and recommendation. - Graph auto-layout improvement for brand new node clients. - Avoid showing setup warning when no server settings have changed. - Fixed JACK D-Bus settings for MIDI driver parameter.

should JACK programs autostart the server?

by bill-auger

the debian maintainer of freewheeling suggested that it should autostart the server if it is not running (change JackNoStartServer to JackNullOption) i have my opinion; but i am interested in others https://sources.debian.org/src/freewheeling/0.6.4-1/debian/patches/060_jack…

Yoshimi V 1.5.9

by Will Godfrey

Amongst many other things this will have a new child of the 'About' window. This will consist of an acknowledgement of all the people who've helped Yoshimi in some way. If anyone particularly *doesn't* want their name on it please let me know. Then again, if there are missing names I'd like to know about that too! This list (Yoshimi_Helpers) has only existed in the source files since V 1.5.1 and is my best attempt at finding everybody. Release is planned for later this month. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

connect(2) call to /dev/shm/jack-0/default/jack_0 failed (err=No such file or directory) (again...)

by Fokke de Jong

Hi all, Sorry to bother you again with this. I’m running into the same problem again as before (see the latter part of the [LAD] jackd not using jackdrc… thread). And apparently my last fix involved some magic rather than replicable logic… :-( i.e. the problem seems to have disappeared on that system, without knowing exactly why) Now I am installing my jack client again on another fresh install of ubuntu 17.04. and a get the same error. I have installed jackd1, to be exact, these packages are current. jackd/artful,artful,now 5 all [installed,automatic] jackd1/artful,now 1:0.125.0-2 amd64 [installed] jackd1-firewire/artful,now 1:0.125.0-2 amd64 [installed,automatic] libjack0/artful,now 1:0.125.0-2 amd64 [installed] qjackctl/artful,now 0.4.5-1ubuntu1 amd64 [installed,automatic] when I start my client jackd is automatically started but i get the error: connect(2) call to /dev/shm/jack-0/default/jack_0 failed (err=No such file or directory) By browsing the jack sources i found the message seems to come from libjack/client.c in server_connect() peeking into the /dev/shm directory it seems /dev/shm/jack-0/default/jack_0 is briefly created,but disappears again, presumably just before the client is able to connect. I have been breaking my head over this, but I really have no clue why this is happening, especially as this has worked fine in the past. I would really like to know what could possibly cause this error and how to fix it. thanks, fokke

OSC

by Christopher Arndt

>From the LAU list: Am 08.09.18 um 17:23 schrieb Len Ovens: > I would be willing to help with a govering body if there are others so > inclined. I'd definitely be interested in helping OSC staying relevant. I've dabled with different OSC-to-X bridges in the past. [1] [2] [3]. My main interest is controlling applications, which talk to some MIDI device, running on a desktop or Raspi or similar, from another application on an Android device, since MIDI and USB-OTG support on Android devices is still somewhat a matter of luck. The protocols I've seen so far, which embed MIDI in OSC are often too simplistic. If I can't transmit Sysex, for example, it's no use to me. And what is the advantage of the verbose commands MidiOSC/midioscar use over just using the MIDI data type OSC provides? Also, the MIDI specification has had a few additions in the past years and a OSC-MIDI protocol hould make sure to support those as well.
