python-osc udp_client.UDPClient() - How do I figure out the reply-to IP?

by Kevin Cole

Hi, In pythonosc (https://pypi.python.org/pypi/python-osc) after connecting with udp_client.UDPClient(...) from a "client", how can I detect the IP to respond to in the "server"? If I explicitly supply the return IP in the server's udp_client.UDPClient(...) call it works. But I want the server to listen for an incoming connection or call on a particular port and figure out who sent it and reply to that IP. I have no network-fu. Thanx! -- @ubuntourist

[ANN] Qtractor 0.7.8 - The Snobby Graviton is out!

by Rui Nuno Capela

Qtractor 0.7.8 - The Snobby Graviton is out! ------------------------------------------- So it's first solstice'16... The world sure is a harsh mistress... yeah, you read that right! <a href="http://en.wikipedia.org/wiki/The_Moon_Is_a_Harsh_Mistress">Heinlein's Moon</a> have been just intentionally rephrased. Yeah, whatever. Just about when the UK vs. EU is there under close scrutiny and sizzling winds of trumpeting (pun intended, again) coming from the other side of the pond, we all should mark the days we're living in. No worries: we still have some feeble but comforting news: Qtractor 0.7.8 (snobby graviton) is out! Nevertheless ;) 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: - MIDI file track names (and any other SMF META events) are now converted to and from the base ASCII/Latin-1 encoding, as much to prevent invalid SMF whenever non-Latin-1 UTF-8 encoded MIDI track names are given. - MIDI file tempo-map and location markers import/export is now hopefully corrected, after almost a decade in mistake, regarding MIDI resolution conversion, when different than current session's setting (TPQN, ticks-per-quarter-note aka. ticks-per-beat, etc.) - Introducing LV2 UI Show interface support for other types than Qt, Gtk, X11 and lv2_external_ui. - Prevent any visual updates while exporting (freewheeling) audio tracks that have at least one plugin activate state automation enabled for playback (as much for not showing messages like "QObject::connect: Cannot queue arguments of type 'QVector<int>'"... anymore). - The common buses management dialog (View/Buses...) sees the superfluous Refresh button finally removed, while two new button commands take its place: (move) Up and Down. - LV2 plug-in Patch support has been added and LV2 plug-ins parameter properties manipulation is now accessible on the generic plug-in properties dialog. - Fixed a recently introduced bug, that rendered all but one plug-in instance to silence, affecting only DSSI plug-ins which implement DSSI_Descriptor::run_multiple_synths() eg. fluidsynth-dssi, hexter, etc. Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://download.sf.net/qtractor/qtractor-0.7.8.tar.gz - source package: http://download.sf.net/qtractor/qtractor-0.7.8-26.rncbc.suse.src.rpm - binary packages: http://download.sf.net/qtractor/qtractor-0.7.8-26.rncbc.suse.i586.rpm http://download.sf.net/qtractor/qtractor-0.7.8-26.rncbc.suse.x86_84.rpm Git repos: http://git.code.sf.net/p/qtractor/code https://github.com/rncbc/qtractor.git https://gitlab.com/rncbc/qtractor.git https://bitbucket.org/rncbc/qtractor.git Wiki (on going, help wanted!): http://sourceforge.net/p/qtractor/wiki/ License: Qtractor [1] is free, open-source Linux Audio [5] software, distributed under the terms of the GNU General Public License (GPL [6]) version 2 or later.

[ANN] Vee One Suite 0.7.5 - The Tenth beta is out!

by Rui Nuno Capela

Hiya! The 'Vee One Suite' aka. 'the gang of three' old-school 'homebrew' software instruments, respectively synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer and drumkv1 [3] as one drum-kit sampler, are here released once again, now in their tenth reincarnation. All still available in dual form: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. The esoteric change-log goes like this: - LV2 Patch property parameters and Worker/Schedule support are now finally in place, allowing for sample file path selections from generic user interfaces (applies to samplv1 [2] and drumkv1 [3] only). - All changes to most continuous parameter values are now smoothed to a fast but finite slew rate. - All BPM sync options to current transport (Auto) have been refactored to new special minimum value (which is now zero). - In compliance to the LV2 spec. MIDI Controllers now affect cached parameter values only, via shadow ports, instead of input control ports directly, mitigating their read-only restriction. - Make sure LV2 plug-in state is properly reset on restore. - Dropped the --enable-qt5 from configure as found redundant given that's the build default anyway (suggestion by Guido Scholz, while for Qtractor, thanks). The Vee One Suite are free, open-source Linux Audio [9] software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later.

mididings not compatible with Boost 1.60 ?

by Jonathan Brickman

Just tried to run a mididing [sic?] with Boost 1.60. Using the latest git of mididings. Got this: TypeError: No to_python (by-value) converter found for C++ type: boost::shared_ptr<mididings::backend::BackendBase> I found many similar reports with other tools, all referencing Boost 1.60, all talking about reverts to Boost 1.5* as the solution. Anyone have other ideas? I'd rather not revert Boost if I don't have to do so. -- *Jonathan E.
