Just a heads up for anyone likely to come across this. It now hides some internal elements that were accessible in V2.x so you might be advised to review your code - it bit us with Yoshimi :( -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[ANN] Vee One Suite 0.9.5 - The End of Winter'19 Release

by Rui Nuno Capela

Dear all, The 'Vee One Suite' of so called 'old-school' software instruments are here and again released for the 'End of Winter'19 season. Available in dual form as usual: - 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 change-log for this end-of-season are as follows:<ul> - Improved overall stability for current sample offset and loop range, cross-fade and zero-crossing property changes across UI's, eg. LV2 plug-in native GUI and a host generic provided one. (applies to samplv1 [2] and drumkv1 [3] only) - HiDPI display screen support (Qt >= 5.6). - A fake/visual piano-keyboard widget is now being introduced to the status bar. - Avoid destructing the possibly shared QApplication instance on LV2 plug-in UI clean-up. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. And here they are in order of 'historical' appearence: **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.5 (end-of-winter'19) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Any tips for (jack) rt audio thread debug breakpoints?

by Tim

Hi list. When I put breakpoints in gui or non-rt audio thread code, no problems. But when I put breakpoints in rt audio thread code, behaviour is odd. I can continue the program and even have more breakpoints. But when the program tries to close, it hangs inside jack_deactivate(). I must kill it and QJackCtl and finally jackd. At bit cumbersome. Seems breaking into the program hiccups jack. Any tips or settings I can try? I realize pausing the app is kinda crazy and over-qualifies as 'waiting too long in an rt thread' but it seems to get so far and work OK but fails at the end. Can it be helped? Thanks.

[ANN] Qtractor 0.9.5 - A Valentines'19 Hotfix Release

by Rui Nuno Capela

Hello again, Qtractor 0.9.5 (valentines'19 hotfix) is out! Changes for this hot-fix release are as follows: - HiDPI display screen support (Qt >= 5.6; patch by Hubert Figuiere, thanks). - Fixed for DSSI plug-ins (eg. fluidsynth-dssi) loss of configuration state: clear internal config/state keys on release virtual method. (REGRESSION) - Fixed for NSM (and JACK) sessions not saving the correct file references/symlinks of clips that are recorded or created during the initial and scratch session. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

The Pac-u-lator: A "mach" object ;-)

by Kevin Cole

Hi, While not strictly Linux or "audio", I have a project that MAY interest some folks here: For gainful employment, I'm involved with a research project that uses the Pacarana sound engine from Symbolic Sound. It comes with a proprietary application, Kyma (pronounced "kee-ma"), which uses drag 'n' drop "patch bay" and a variant of Smalltalk which Symbolic Sound has named "Capytalk". But the box also understands OSC. However, my access to the box is limited. So, in order to test out my code I've built an ... emulator isn't quite the word... mock object, I guess, to acknowledge my OSC messages with appropriate responses (but no audio) when I'm not in the same room as the Pacarana. The code is written in Python 3 and lives out on: https://gitlab.com/ubuntourist/paculator Right now the CLI stuff works well enough for my purposes, and there's the rudiments of a GUI reproduction of Kyma's Virtual Control Surface (VCS). The GUI portion requires PySide which requires Qt. Also, it advertises itself via mDNS / Bonjour / Zeroconf / avahi. It lives in the newer pipenv virtual environment. I'm both proud of it and embarrassed by it. ;-)

[ANN] Qtractor 0.9.4 - The Winter'19 Release

by Rui Nuno Capela

Dear all, Qtractor 0.9.4 (winter'19 beta) is released! Changes for this season are as follows: - Drag-moving and copy-pasting existing clips, while over the main track-view, now shows the respective (audio wave-shapes and MIDI piano-rolls) graphical representations, as much as possible. - For good and bad, session name changes now trickle down to respective audio/MIDI file names as well. - Audio output monitoring meters may now be shown on MIDI tracks and buses as a default user preference option (View/ Options.../Plugins/Instruments/Show audio output monitoring meters) and also in plugin list context sub-menu (Audio/Meters). - Custom color (palette) themes can be exported to and imported from external files. - LV2 plug-in UI GTK2 and X11 in Qt5 host native support are now enabled on configure by default. - Fixed minimum input value as 10% (was 1%) for audio clip time-stretching in the Clip / Edit... dialog. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
