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.

Re: [LAD] send midi message

On Friday 06 January 2012, you wrote: > btw: is there a way to list available clients/ports from the api. > I know that aconnect -i / -o does this, but is there a c/c++ function? > > Dave The functions are: snd_seq_query_next_client() and snd_seq_query_next_port(); you need to loop calling these functions while they return a correct answer. 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

[ALPHA] ladspa.m.lv2 - Some questions :D

by Florian Paul Schmidt

Hi, These last few days I found some time to work on ladspa.m.lv2, an LV2 plugin to load ladspa.m.proto instrument definition files: https://github.com/fps/ladspa.m.lv2 It is in a somewhat usable state, i.e. used in ardour3 it loads the example instrument generated by this python script: https://github.com/fps/ladspa.m.proto/blob/master/example_instrument.py which is a very simple polyphonic sawtooth synth with exponential envelopes and an echo with differing delay times per voice. There's still some things to do (e.g. expose control ports, implement All-Notes-Off midi messages, lots of optimizations - right now I care more for correctness than for efficiency, etc.) and I also have some questions: 1] This one is regarding waf. I'm not used to writing wscript files and I adapted the whole thing from the example sampler from the LV2-distribution. I wonder how I can make waf to use e.g. -fPIC and other compiler flags needed for my 64-bit system. Right now I have put a little makefile into the repository which passes the missing options along as CXXFLAGS environment variable. This is a dirty hack. So if anyone waf guru might want to take a look, I'd be so ever grateful. https://github.com/fps/ladspa.m.lv2/blob/master/makefile https://github.com/fps/ladspa.m.lv2/blob/master/wscript 2] I'm a little bit puzzled by how the patch_set messages together with the LV2 worker extension works. If you take a look at this run() function https://github.com/fps/ladspa.m.lv2/blob/master/instrument.cc#L702 you'll see that I have an extra LV2_ATOM_SEQUENCE_FOR_EACH at the start of the function to process the patch_set messages. I tried to integrate that into the loop later on (that iterates over the sample_count frames and lets the midi events take effect at their respective frame), but once I do that, patch loading stops to work. I must be missing something fundamental. So if any LV2 guru might want to take a look, I'd be very grateful, too Thanks and have fun, Flo -- Florian Paul Schmidt http://fps.io

Laborejo 0.7: Non-Session-Manager support, Playback Cursor, Numpad Palette

by Nils Gey

Laborejo 0.7 is released. Together with a new website design http://www.laborejo.org comes a new release of the Music Notation Workshop. Besides the usual fixes and small enhancements please focus your attention on the following new features: -Non Session Manager support. Start Laborejo through the NSM Gui and it will be under session management -Numpad Palette and corresponding shortcuts. A gui widget shows you what musical objects your numpad will insert. You can change the palette through the menu or by switching through with numpad-plus and numpad-minus. -A moving playback cursor, showing you which part of Bachs "Kunst der Fuge" you currently don't understand Laborejo -Music Notation Workshop- is a graphical user interface for Lilypond, a MIDI creator and finally a tool collection to inspire and help you compose. You get beautifully engraved notation through Lilypond and nice ways to control the playback without ever leaving a notation-based environment. Latest Screenshot: http://www.laborejo.org/latestscreenshot.png Instructions and Download Page: http://laborejo.org/Download Greetings, Nils Gey http://www.laborejo.org #laborejo on irc.freenode.org
