[LAD] ANN: faust-lv2 1.0 and faust-vst 1.0 released

by Albert Graef

(Sorry for cross-posting.) Dear Faust programmers and LAD'ers, New stuff just in time for the upcoming miniLAC @ Berlin next week! faust-lv2 and faust-vst are two architectures for Grame's functional dsp programming language Faust. They let you create fully functional LV2 and VST plugins from Faust programs. Most notable changes: - Custom Qt GUI support. This leverages Faust's Qt support (faustqt.h) and was done by one of my students, Roman Svidler, for his BSc thesis. Thanks Roman! - The custom 'nvoices' meta key is now recognized by both architectures to denote an instrument plugin, so a single architecture suffices to implement both instrument and effect plugins. - Both architectures now work exactly alike, so porting your Faust plugins from LV2 to VST and vice versa just takes a recompile. - Many bugfixes and smaller improvements, please check the commit logs for details. The latest sources including documentation and examples are available from Bitbucket: https://bitbucket.org/agraef/faust-lv2 https://bitbucket.org/agraef/faust-vst Please use the issue trackers there to report any bugs that you find, thanks! The architecture files and helper scripts are also included in the latest Faust git sources, so if you keep your Faust installation up to date, chances are that you already got them. Both architectures are now also available through the Faust online and remote compilers, thanks Yann! So you can give them a try immediately without having to install anything. Simply head over to http://faust.grame.fr/onlinecompiler/, drop one of the dsp examples provided in the faust-lv2|vst Bitbucket repositories or your own Faust sources there, choose one of the linux lv2 or vst architectures as target and go to the Exec tab to receive your freshly baked plugin. If you can make it to Berlin, I'll be showing both faust-lv2 and faust-vst there in the main hall of c-base on Saturday (April 9) at 3 p.m., would be nice to meet you there! Enjoy! :) Albert -- Dr. Albert Gr"af Computer Music Research Group, JGU Mainz, Germany Email: aggraef(a)gmail.com WWW: https://plus.google.com/+AlbertGraef

[LAD] Drumgizmo 0.9.10 released

by Bent Bisballe Nyeng

We're proud to announce the immediate availability of DrumGizmo version 0.9.10! DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that has been recorded with a multimic setup. This is a bugfix release fixing two major bugs: - Resampler now works when using DrumGizmo as a plugin. - LV2 plugin no longer freezes on tempo changes. Download it from http://www.drumgizmo.org Visit us at the official irc channel at the Freenode network. Channel name #DrumGizmo. We would love to hear from you! // The DrumGizmo team

[LAD] Advanced Gtk+ Sequencer v0.7.0 stable

by Joël Krähemann

Hi all GSequencer version 0.7.10 got released as stable. Plugin support has been extended from LADSPA to DSSI and LV2. Although it's not yet perfect some of those plugins can be used for now. It needs further investigation why certain plugins don't work. For now values from GUI get converted to appropriate scale. Rudimentary MIDI input exists as well but it wasn't tested, yet. For sequencers and instruments there exists a connection editor supporting JACK and ALSA backend. Theoritcally you should be able to output to JACK using GSequencer. But JACK support needs some fixes because you can't link jackserver and jack both in the same application. http://gsequencer.org bests, Joël

[LAD] rtp-MIDI status

by Alessio Degani

Hi, sorry for cross-posting, I'm wondering which is the current status fpr the rtpMIDI protocol suppurt under Linux. As far as I know, there was midistream but is not maintained anymore. Midistream was merged in a Scenic, but Scenic is a "huge" piece of software. I need only rtpMIDI support. There are some other solitions? It would be nice if rtpMIDI, since it is a sort of stadard, will be integrated directly in Jack (or ALSA?... humm, i think that rtpMIDI is more a Jack thing). What do you think about it? Cheers -- a.

[LAD] [ANN] Qtractor 0.7.5 - The Hazy Photon is out!

by Rui Nuno Capela

Hello everybody! Qtractor 0.7.5 (hazy photon) is out! It comes with one top recommendation though: please update, at once, while it's hot! :) Highlights for this dot/beta release: * Overlapping clips cross-fade (NEW) * MIDI Send/Return and Aux-Send insert plugins (NEW) * Generic and custom track icons eye-candy (NEW) Some other interesting points may be found in the blunt and misty change-log below. And just in case you missed it before, 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. Change-log (since last tacky release): - Beat unit divisor, aka. the denominator or lower numeral in the time-signature, have now a visible and practical effect over the time-line, even though the standard MIDI tempo(BPM) is always denoted in beats as quarter-notes (1/4, crotchet, seminima) per minute. - Fixed an old hack on LV2 State Files abstract/relative file-path mapping when saving custom LV2 Presets (after a related issue on Fabla2, by Harry Van Haaren, thanks). - Default PC-Keyboard shortcuts may now be erasable and re-assigned (cf. Help/Shortcuts...). - New option on the audio/MIDI export dialog, on whether to add/import the exported result as brand new track(s). - Introducing brand new track icons property. - Old Dry/Wet Insert and Aux-send pseudo-plugin parameters are now split into separate Dry and Wet controls, what else could it possibly be? :) - Brand new MIDI Insert and Aux-Send pseudo-plugins are now implemented with very similar semantics as the respective and existing audio counterparts. - Implement LV2_STATE__loadDefaultState feature (after pull request by Hanspeter Portner aka. ventosus, thanks). - Plug-ins search paths internal logic has been refactored; an alternative file-name based search is now in effect for LADSPA, DSSI and VST plug-ins, whenever not found on their original file-path locations saved in a previous session. - Finally added this brand new menu Clip/Cross Fade command, aimed on setting fade-in/out ranges properly, just as far to (auto)cross-fade consecutive overlapping clips.

[LAD] LV2 plugin host MIDI channel number detection

by Yassin Philip

Hello! Some LV2 plugins seem to now the MIDI channel # of the track on which they are inserted, and some don't. If I had to guess I'd say that nobody knows, only some plugins can receive data from several MIDI channels, and some only work with one, so they never mistake ; Am I right? Last year I made a GUI around so-404 to learn about LV2 (and C, C++, DSP code, etc. :)) ; And it has the same problem, just sightly different: Worse: It starts numbering at 0, so if it's inserted on a track w/ MIDI #4, you have to select 3 Better: It remembers said channel # on session reload (ZynAddSubFx doesn't. Yoshimi does) Can somebody point me towards the light? I'd like my plugin to only listen to one channel: The one of the host track it's inserted into. yPhil -- Philippe "xaccrocheur" Yassin http://manyrecords.com http://bitbucket.org/xaccrocheur / https://github.com/xaccrocheur

[LAD] Multiple JACK servers connected in one host?

by Jonathan E. Brickman

Greetings, everyone. Since I am using 85% of JACK DSP in my primary production box, while using 14% of the CPU and 1/8 of the RAM according to htop, it appears that I need to develop a way to move forward :-) It is very clear from the excellent Patrick Shirkey's input that one can use netjack to chain any combination of motherboards each running JACK; I would like to use the power of my box to do the same internally. I have taken a number of hours over the last few days in testing. Thus far, my impression is that netjack1, netjack2, and jacktrip are explicitly not set up for this. Using jack2, netjack1 and jacktrip worked fine for one client/slave, but a second one froze both, and netjack2 did not work at all, I found a web reference stating that multijack explicitly does not do localhost unless explicitly set to do so at the TCP/IP stack programming level. Using jack1, netjack1 did not connect at all, so I decided to halt for now and ask Those Who Know :-) So far, the only clearly workable option, has been to try the Docker lightweight virtualizer, and run each JACK server and related application chain in its own container. Anyone have better ideas? -- Jonathan E.
