Hey everyone! I have created a YouTube channel where I am creating playlists of ambient music. As many of you have told me that they enjoy listening to "droning" and other of my ambient creations during work, I have created "Music for programming" mixes. Some of them might feature just one tune, some feature several tunes. Take your pick - and subscribe!

Help: OSC + DSSI not working, at least on openSUSE

by Tim

Hi list. Strange problem here. Any verification especially on other OSs, solutions, comments, observations appreciated. Neither QTractor nor MusE will open any DSSI gui here on OpenSUSE Tumbleweed x86 64 bit. I have built liblo-0.29, and to test, Hexter 1.0.3, and removed their SUSE packages. Same problem. I traced the problem. liblo *silently* fails: liblo: src/address.c: line 594: if ((ret = getaddrinfo(host, lo_address_get_port(a), &hints, &ai))) ... I turned on hexter debugging, and added my own to liblo and hexter: ------------------------------ initOSC() url:osc.udp://linux-2lbs:19899/ .... [Some MusE output stuff] hexter.so hexter_get_program called with 0 .... [More hexter program stuff] hexter.so hexter_get_program called with 128 hexter.so hexter_get_midi_controller called for port 1 hexter.so hexter_get_midi_controller called for port 2 hexter.so hexter_configure called with 'DSSI:PROJECT_DIRECTORY' and './' hexter.so hexter_get_midi_controller called for port 1 hexter.so hexter_get_midi_controller called for port 2 OscIF::oscShowGui(): v:1 visible:0 OscIF::oscShowGui(): No QProcess or process not running. Starting gui. OscIF::oscInitGui TIM: hexter_gtk main() start hexter_gtk starting (pid 21264)... hexter_gtk: listening at osc.udp://linux-2lbs:14372/dssi_synth/hexter/hexter-0 hexter_gtk: rebuild_patches_clist called hexter_gtk: update_performance_spin called for 'pitch_bend_range' with 2 hexter_gtk on_performance_spin_change: skipping further action .... [More spin stuff] TIM: hexter_gtk main(): osc_host_address:0x1c1e8f0 TIM: hexter_gtk main(): osc_configure_path:/dssi_synth/hexter/hexter-0/configure .... [More similar paths] TIM: hexter_gtk main(): osc_update_path:/dssi_synth/hexter/hexter-0/update TIM: hexter_gtk main(): calling gtk_main()... TIM: hexter_gtk update_request_timeout_callback(..): calling lo_send(..)

Error: Timeout - synth gui did not start within 20 seconds. ------------------------------ What's going on here? The name (linux-2lbs) and service (port number 19899) are valid. That's the URL given to MusE by liblo when we start the OSC server thread. And we pass that to the gui executable. When I run "hexter -test" the gui *does* appear: ------------------------------ TIM: TIM: hexter main() start hexter_gtk starting (pid 23447)... hexter_gtk: listening at osc.udp://linux-2lbs:16029/test/mode hexter_gtk: rebuild_patches_clist called hexter_gtk: update_performance_spin called for 'pitch_bend_range' with 2 .... hexter_gtk: update_performance_assign called for 'breath_assign' with 2 TIM: osc_host_address:0x90bc60 TIM: osc_configure_path:/test/mode/configure .... TIM: osc_update_path:/test/mode/update TIM: hexter main(): calling gtk_main()... .... [gui is now showing] hexter_gtk on_test_note_button_press: button pressed TIM: lo_address_resolve host:localhost port:9 hexter_gtk on_test_note_button_press: button released ------------------------------ I added a full range of UDP allowances in my firewall and even tried turning it off completely, thinking it was a UDP blockage thing, but no luck. Something further to do? The only difference I see is host "linux-2lbs" vs. "localhost" but the former is in fact my machine name. Hexter does a few tricks to run in test mode, so I'm not sure how relevant the second test is (with "hexter -test"). Thanks. Tim. The MusE Sequencer project.

[ANN] Vee One Suite 0.8.5 - An Autumn'17 release

by Rui Nuno Capela

Howdy! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here released for the seasonal greetings. All still available in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The common change-log for this Fall goes like this: - Sample files are now saved as symlinks when saving to JACK and/or NSM session directories/folders (applies to samplv1 [2] and drumkv1 [3] only). - Opening multiple preset files is now possible, populating the preset drop-down listing, while only the first one is loaded effectively into the scene as usual. - Mono(phonic) "Legato" mode option introduced. - Desktop entry specification file is now finally independent from all build/configure template chains, whatever. - Updated target path for freedesktop.org's AppStream metainfo file (formerly AppData). And now, in reverse order of appearance: **padthv1 - an old-school polyphonic additive synthesizer [4]** padthv1 0.8.5 (autumn'17) released! padthv1 is an old-school polyphonic additive synthesizer with stereo fx padthv1 is based on the PADsynth algorithm by Paul Nasca, as a special variant of additive synthesis.

"Sonoj", a community organized event about Open Source Music Production struggles to get funded. Please help

by Nils, Sonoj Convention

(Disclaimer: I am an organizer of this event) In less than a month the "Sonoj Convention" shall happen. [quote]Admission is free. You will be able to enjoy demonstrations, talks and workshops about music production through open source software. Hands-on tutorials and workflow presentations can be expected. Everything will be recorded and released as online videos afterwards. [/quote] Please consider helping us by donating and spreading the word. You will get some appreciation through the "Reward" system on the website. For that we are asking for some modest donations here: https://www.startnext.com/en/sonoj Currently it looks like that this will not succeed, as you can see from the link above. This is the usual "all or nothing" platform that only gives you money if the goal is reached, otherwise donors get their money back. However, despite submitting the event announcements and several updates to nearly one hundred on-topic websites, magazines (including posting it ourselves on KVR, Reddit etc.) and blogs there is nearly zero response. That excludes the Linux Audio Scene itself, which was very supportive to this day (at least the news, not the donations). I was hoping that Sonoj could be an event that brings in people from the "outside", that are not already well connected with Linux Audio. It seems I was wrong. So here I am in one of the last places I wanted to ask for donations, because this is the crowd that usually already gives a lot, be it their own time, development of software or actual donations to well deserving projects. Please consider helping us by donating and spreading the word. You will get some appreciation through the "Reward" system on the website. https://www.startnext.com/en/sonoj Yours Nils, for the Sonoj Convention https://www.sonoj.org

Jitter analysis

by benravin

Hi, I'm facing a timing jitter which happens periodically due to some interrupt, which is causing the task to be delayed. Since this happens periodically, it is indeed a slow varying timing jitter, for example every 400ms, the timing deviation is in the order of few ms ( 4-6ms). This is not getting filtered out by DLL, and results in a slow varying oscillations which never dies. Any way to identify and limit these timing jitters and not to take any action on drift correction by DLL ? -ben -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-dev-f58952.html

GNU Guitar 0.4.0-alpha released

by Taylor

GNU Guitar is a guitar effects processor, much like Guitarix and Rakarrack. It was started about ten years ago, formally known as GNUitar. Over the last year, it has been refactored (and some parts completely rewritten) to use modern software technologies. It's cross-platform, so it runs on Linux systems and Windows (macOS is on the to-do list). Here's a link to the change summary: https://github.com/gnu-guitar/gnu-guitar/releases/tag/v0.4.0-alpha The project is in it's infancy still. Let me know if you're interested in contributing!
