Re: [linux-audio-dev] Which sequencer framework for a simple MIDI drum looper ?

by _ langagemachine

Yes, a lot of research has obviously been put into this library ; the fact that it has plenty of language bindings (java, lisp, python) is attractive also. Plus, the JMusic project provides classes for manipulating musical data, and an interface to Midishare... I will make some tries at it on a CCRMA box, I think. Thanks for your feedback :-) On a more general keynote, is it not paradoxical that when a piece of software becomes mature enough, it tends to fade out of the general attention ? 2006/8/15, Jay Vaughan <jayv(a)synth.net>: > I work with MidiShare quite a bit, and I have to say that if you get > it going on your system, it really is one of the nicest, > best-performing MIDI API's around .. of course the fact that it comes > with a Sequencer lib that supports up to 256 tracks is a bonus too .. > ;) > > That said, it may not be quite "ALSA mainstream" enough of an API to > warrant usage, but if you have control over your system and get > MidiShare.o built and in use, you've got a damn fine MIDI API, > oft-overlooked .. > > -- > > ; > > Jay Vaughan > >

[linux-audio-dev] 2.6.15.7-rt

by Joshua Boyd

I just upgraded my LFS 6.1 system from 2.6.12 (with preempt, but not the -rt patch) to 2.6.15-rt (enabling high resolution timers and PREEMPT_RT along the way), and now my audio driver is dropping interrupts every few seconds, something it wasn't doing before. I haven't configured rtlimits since the program runs as root anyway, and I'd like it to be free to hog quite a lot if need be. In my application (which runs in SCHED_FIFO), the audio thread runs at -10, while the video thread runs at -19. I don't know if that is best, I just wanted them to be higher than the other threads. Also, outside forces, like a ssh connection, or a USB dongle connection cause the program to drop audio madly. Is there some code I need to be adding to force such system tasks down rather than just elevating my own application? -- Joshua D.

[linux-audio-dev] LV2 and Linuxaudio.org

by Ivica Ico Bukvic

To all involved in the LV2 project, I would greatly appreciate your feedback regarding LV2 project becoming a member of Linuxaudio.org. Provided that you decide this is a step they wish to take, it would be a good idea to nominate someone as the representative of the project within the consortium. Please advise. Best wishes, Ivica Ico Bukvic, D.M.A. Linuxaudio.org Director Virginia Tech Department of Music - 0240 Blacksburg, VA 24061 (540) 231-7047 (540) 231-5034 (fax) ico(a)vt.edu http://www.music.vt.edu/people/faculty/bukvic

Well, it bothered me you didn't even reply with a simple "not interested". Wanted to provide some hooks for Ico to say something about what the consortium is and isn't about. I'm sorry for trying to provoke you to step forward by use of attempted humour by exaggeration (somehow i thought nobody would take a something starting with "50% of the core team" dead serious). I don't see where stereotypes come into play (to me, you're a type of his own :p Nothing of this was meant as accusation. -- Thorsten Wilms "Jetzt Handykosten senken mit klarmobil - 14 Ct./Min.!

[linux-audio-dev] [admin] spam handling on the linux-audio-* lists

by Joern Nettingsmeier

hi everyone! just fyi, the amount of spam in the moderation queues has risen to such an extent that the server admin, douglas repetto of columbia university, has implemented an auto-clear function for the queues. that means: if your message is not forwarded to the list, it will be dead, gone and forgotten. this happens either if you are using a non-subscribed address to post (regardless of whether you are subscribed with another account, even if it's in the same domain, i.e. if j(a)example.com is legitimate, j(a)dork.example.com will bounce), or if mailman determines you are posting html. due to a misunderstanding, this auto-nuking has been active on linux-audio-announce as well for the past couple of days. so if you tried to get an announcement out, please resend - the old one went straight to the bit bucket. regards, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 if you are a free (as in "free speech") software developer and you happen to be travelling near my home, drop me a line and come round for a free (as in "free beer") beer. :-D

Hi! What is quickest way to determine is JACK server running or not? Just jack_client_open() call with JackNullOption takes about 5 sec when the server is not running. Andrew
