Hi I'm working on port my GTK based LV2 UI's to plain X11 cairo UI's. So far I've anything in shape now. The last remaining issue I've is UI resizing in Qtractor. It seems that the Qtractor parent UI ain't forward the ConfigureNotify to the embedded window. So, when the parent window is resized by the user, the embedded window ain't get notified, so it can't resize itself to fit the parent window size. Anyone else noticed that behavior, or, is it a known behavior, or, do I do something wrong? Resizing works in Carla, Ardour and jalv. regards hermann

Re: [LAD] How to ask?

by John Murphy

Hi Phil and list, The object is to end up with a very functional 'compilation compiler'. I have hundreds of old recordings of music radio and I use audiotag to find regions within those .wav files. The version 0.7 I have outputs region information on std-out like: REGION "/path/Wed0301.wav" 01:37:31.35310 01:41:27.19055 (saved 2018 09 30 T 13 18 08) I know that Qt can start non gui programs and absorb the outputs from them, so each time I click add, a new entry would be made in a database (SQlite preferably) and I'd be able to manually add Artist, Title, Label and some notes. Maybe genre and a numeric, or star scoring option as well. The regions are playable with 'dump' (which is part of 0.7, but isn't included in 0.6) either individually or as a sequence. It's input is a plain text file of one or more of those REGION lines. With very many regions added to the database, I'd want to be able to audition any one of them and add it to a new list/compilation, or maybe edit old ones with newer tunes, or simply play a favourite compilation. Previous / Repeat / Next buttons would be good. Additionally, I'd like to be able to save the regions as new individual .wav etc. files, or as one new large one of the whole compilation, but it isn't the main requirement as I can record while playing (I've read). Also, larger text for Head PlayHead and Tail positions in audiotag would help me see what I'm doing. Thanks. I may not have explained it well, so please ask if anything is still not clear. John.

How to ask?

by John Murphy

FOSS developers are so generous that all users are already in their debt and already I fear may have upset some by saying so. You/they have my admiration, but it doesn't seem enough and the debt remains. Occasionally I see an opportunity to help, if a developer hints they're near starving, or I can dispose of some hardware in someone's direction... But, to the point. I'm currently using a fabulous little suite of tools which were almost written for me by a gifted dev.. http://sed.free.fr/audiotag/ (although the version I have is 0.7) I clumsily and regrettably offered that despicable symbol of capitalism - money (or goods) to show appreciation. I don't even feel able to ask for more from sed and I said I would write a GUI and some database code to develop it to an actual application, but I can't, or I could, but it would be a mess which I could only keep to myself. It would be barely usable, even after a lot of head scratching. May I humbly ask how to ask to pay for some development? As my time runs out in old age, I'd much rather enjoy using software than experience the real discomfort I feel when I try to code, but having used it since the beginning, maybe I can see ways of using software more intuitively than some. I may well be the fastest audiotagger in the universe! How to proceed? I duckducked for Linux developers, but thought I should ask here first. -- Thanks for everything, regardless. John.

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!

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
