scheduled server downtime - 10/Jan/12 - linuxaudio.org

by Robin Gareus

Hi all, As you may or may not have noticed, linuxaudio.org was rebooted today 15:06 UTC. The server now features shiny (faster) new virtual HDDs (with backups and everything..). Sponsored by the Virginia Tech Department of Music and DISIS. Cheer a loud "Hip Hip,..." to Ico, who made it possible in the first place and send Kudos to Brian Maloney from the vt.edu tech dept for outstanding excellent GNU/Linux support! All systems go. robin

ganv build error: error: ISO C++ forbids declaration of ‘cairo_region_t’ with no type

by Diego Simak

Hi all, I don't really know if this email should be directed to LAD, or LAU or just Drobilla devs... anyway: I'm trying to build Ingen from SVN using all LV2 files (packages, extensions, tools, etc.) from SVN as well. During ganv build stage I'm getting this error: /home/diego/Desktop/ingen/drobilla-lad/ganv/ganv/canvas-base.h:259:2: error: ISO C++ forbids declaration of ‘cairo_region_t’ with no type /home/diego/Desktop/ingen/drobilla-lad/ganv/ganv/canvas-base.h:259:16: error: expected ‘;’ before ‘*’ token .....and the build just fails. I know that there's a ticket 792 [1] opened about this issue but I would like to know if there is some simple solution to solve this error. I'm on Ubuntu 10.04 with libcairo2-1.8.10. Thank you very much. Diego [1]: http://dev.drobilla.net/ticket/792

[OT] Statistics about usage of GUI toolkits

by Julien Claassen

Hello everyone! Does anyone of you know about a good resource for statistical info about used graphical toolkits? So which toolkits are used the most. Including all platforms would be nice, but info on Linux-based toolkits would be a good start. Thanks and kind regards Julien =-=-=-=-=-=-=-=-=-=-=-=- Such Is Life: Very Intensely Adorable; Free And Jubilating Amazement Revels, Dancing On - FLOWERS! ====== Find my music at ====== http://juliencoder.de/nama/music.html .....................................

JACK Timemachine patch that allows OSC port to be specified at start up

by Tristan Strange

Hi all, I've been trying to get the attached patch to steve at plugin dot org dot uk.... unfortunately his email address has been unavailable for 5 days now. The attached patch allows the OSC port a timemachine instance is listening on to be specified at startup with a -o flag. Can anyone else commit this to the project's git repository whilst he's unavailable (providing it's up to scratch of course!) or forward this on to Steve for me please? This is the first patch I'll have submitted to a well used open source project so I'm super keen to see it in timemachines code base. Many thanks, Tristan

Yes, but this macro snd_seq_ev_set_note() is the only one that includes a duration parameter. It is not really a MIDI message, but the sequencer event is converted into two MIDI messages (noteOn + noteOff). There aren't MIDI messages containing durations. OTOH any event using the macros snd_seq_ev_schedule_real() or snd_seq_ev_schedule_tick() requires a queue as well, because the message delivering time will be scheduled in the future. Events using the macros snd_seq_ev_set_queue_control(), snd_seq_ev_set_queue_start(), snd_seq_ev_set_queue_stop(), snd_seq_ev_set_queue_continue() or snd_seq_ev_set_queue_tempo() also require a queue, because all these macros have a queue parameter.

send midi message

by Dave Stikkolorum

Hi all, I try to write a c program that sends midi notes to the Hydrogen drum sequencer. I use the alsa library to create a client with an output port. I attached two files. loopqueue.c works but loop.c doesn't. A base drum (note:28) is being send. I am not succeeding to use direct delivery, but it only works with the queue. Any ideas why? Regards, Dave
