Support for Steinberg UR22 (Yamaha USB chipset 0499:1509)?

by cullinan＠rocketmail.com

Hi, there! I just got a Steinberg UR22 USB<->Audio / MIDI interface for my semi-prof. DJ work. I am working on Linux (only), but wanted to give this new product a chance. Well, it's basically a nice device but with an Yamaha chipset in it which seem unfortunately not supported from the latest (3.7.9) linux kernel(s). My questions are: - How likely is it to get this device fully supported on linux? - What needs to be done to get this device fully supported? I am an electrical engineer and did some linux device driver development in the past on some DMA stuff, but I am quite new to linux audio. But I am willing to help somewhere... I could try to reverse-engineer the USB stuff on Windows with the usbmon/usbsnoop/libusb things... But if it's too much work, to get it working, I could also just decide to send it back to Steinberg and thank them for not supporting Linux with their products. The USB information I could get is: $ aplay -l doesn't list that device $ lsusb ... Bus 002 Device 016: ID 0499:1509 Yamaha Corp. ... (See the more comprehensive $ lsusb -v below...) Related USB devices are: 0499:1501 Yamaha 0499:1507 Yamaha THR10 0499:1509 Yamaha Steinberg UR22 (what I am talking about) 0499:150c Yamaha THR10C Related search resuls are: Getting a Steinberg CI1 USB audio interface to work http://ubuntuforums.org/showthread.php?t=1696336 Yamaha THR10 amp / USB2.0 audio interface http://linux-audio.4202.n7.nabble.com/Yamaha-THR10-amp-USB2-0-audio-interfa… Thank you, Clemens (different one as in last link) -----8<----- $ lsusb -v -d 0499:1509 Bus 002 Device 014: ID 0499:1509 Yamaha Corp.

For instance, this is the relevant code in "aconnect.c" : static void do_search_port(snd_seq_t *seq, int perm, action_func_t do_action) { snd_seq_client_info_t *cinfo; snd_seq_port_info_t *pinfo; int count; snd_seq_client_info_alloca(&cinfo); snd_seq_port_info_alloca(&pinfo); snd_seq_client_info_set_client(cinfo, -1); while (snd_seq_query_next_client(seq, cinfo) >= 0) { /* reset query info */ snd_seq_port_info_set_client(pinfo, snd_seq_client_info_get_client(cinfo)); snd_seq_port_info_set_port(pinfo, -1); count = 0; while (snd_seq_query_next_port(seq, pinfo) >= 0) { if (check_permission(pinfo, perm)) { do_action(seq, cinfo, pinfo, count); count++; } } } } See: http://git.alsa-project.org/?p=alsa-utils.git;a=blob;f=seq/aconnect/aconnec… I guess you already know the reference documentation site: http://www.alsa-project.org/alsa-doc/alsa-lib/seq.html Just for comparison, a similar enumeration using Drumstick looks like this: QListIterator<PortInfo> it(m_Client->getAvailableOutputs()); while(it.hasNext()) { PortInfo p = it.next(); cout << p.getClientName() << ":" << p.getPort(); } See Drumstick's example "drumgrid": http://drumstick.sourceforge.net/docs/drumgrid.cpp-example.html Regards, Pedro

simple silence detection tool

by Jeremy Hansen

I'm looking for a simple tool where I can point it at an http audio stream, define a number of seconds to detect silence and exit with a non-zero status if silence is detected. It seems like this should be easy but I've been search high and low for such a utility and nothing simple exists. Unfortunately I'm not much of a developer, but this doesn't seem like it would be that difficult. Maybe it's harder than I think, hence no tool that I can find. Thanks -jeremy

Sync Arpage to Hydrogen

by Thijs van severen

Hi all i'm trying to sync arpage (jack synced arpeggiator) to Hydrogen: in hydrogen i enabled jack transport + set hydrogen as master Arpage gets triggered when i hit play in hydrogen, but it does not do what i expect it to do (the tempo is all 'weird') if i do the same with qtractor, ardour or the jack_transport utility as jack master everything works as expected now i'm trying to find an easy way to see if there is any difference between the way hydrogen and the other apps start/stop/'master' the jack transport, but so far i cant see any difference is there any app/utility that can give me detailed info about jack transport ? i have logged a ticket (including a screen recording @ bottom of the ticket) of this strange behavior : https://github.com/hydrogen-music/hydrogen/issues/81 any tips ? grtz Thijs -- follow me on my Audio & Linux blog <http://audio-and-linux.blogspot.com/> !

Licensed for Sampled Instrument Example / Suggestion

by Nils Gey

Hello Developers, I have written a short blog post about what I think is the ideal license for open source sampled instrument libraries. It is in fact either a CC license or GPL, I am not so naive to think I am able to write an entire license, but I have added necessary additions and exceptions. I am not a lawyer and I have no education or official background in law and rights. This is a suggestion, based on my experience with existing licenses and the requirements of sample based virtual instrument libraries, a.k.a "Samples" http://www.nilsgey.de/2013/02/28/License_Proposal_for_Sample_Instrument_Lib… I welcome any comments here or in the blog itself since I know that licenses are a serious matter. And I don't want to make a fool of myself. I remember some weird licenses, even in the linux audio community, and I don't want to create one of them :) Greetings, Nils

python, gtk, gstreamer

by drew Roberts

Ignorant here. Trying to scrounge around and make something work for a demo purpose. In python I am trying to build this pipeline: pipeline_txt = ( 'jackaudiosrc ! ' 'level name=level interval=1000000000 !' 'jackaudiosink') pipeline = gst.parse_launch(pipeline_txt) I have been trying that a number of ways. So, I basically watch the bus for level info. In a subroutine, I can print the peak info to the terminal. I can't seem to figure out how to pass this info back to the rest of the program so that I can hook it up to a graphical meter. Cna anyone point me to some simple code doing something like this? Give me some clues that might help someone who seems to be being very dense for days now? all the best, drew

Floss alternative to red5

by APO33

Hello all, we are working on some development of audio/video web live applications at the moment. We are facing a little problem, maybe some people here already came across. Some people advised us to use red5, an audio/video streaming and multi-user solution to take sound from mic / sound card input + webcam/cam to be streamed online via your browser. The biggest problem we are facing is that is based on adobe closed flash system and it use only proprietary format/codecs such as mp3, flv and h264 :-( We are looking for a way to do the same with floss technologies such as ogg, theora, icecast or others... The idea is that the final user will stream his sound and video with his browser and everyone could see/hear him and do the same via their browser. We are actually testing some solutions with gstreamer but we still need an external client, although we are thinking about using some python script to run on the server to handle gstreamer live stream... but we are not sure... Anyway if any of you have any hints or some floss solutions for that, it would be really highly appreciated :-) thank you cheers Julien -- APO33 space of research and experimentation http://www.apo33.org info(a)apo33.org

Re: [LAD] Puredata slow response

by Ivica Ico Bukvic

Not sure if this is going to help but I did notice with pd-l2ork on a laptop with an AMD video card (fglrx driver) when I have the tearfree (vsync) option enabled pd-l2ork's gui gets very sluggish. Disabling the vsync option makes it fine. On Feb 24, 2013 3:54 PM, "Fons Adriaensen" <fons(a)linuxaudio.org> wrote: Hello all, I'm seeing a strange probelm with Pd.
