esound has a wrapper of some sort that will take most oss applications and play them via esound. Is there some sort of equivalent for jack or perhaps alsa? It would be different from oss emulation in alsa in that it would be user-space and explicitly invoked. I ask for three reasons. The first might just be ignorance, but I can't figure out how to use the oss emulation for my second card - things just play through the first card. Some sort of wrapper could help direct it to wherever I want it to go. The second (if it were jack) is to do mixing. The third reason is I'm curious to see which programs are still using oss, but not curious enough to go look at the docs/source of every program. This way I'd see sound doesn't work but could still run the program with the wrapper and get sound. -- Hans Fugal | De gustibus non disputandum est. http://hans.fugal.net/ | Debian, vim, mutt, ruby, text, gpg http://gdmxml.fugal.net/ | WindowMaker, gaim, UTF-8, RISC, JS Bach --------------------------------------------------------------------- GnuPG Fingerprint: 6940 87C5 6610 567F 1E95 CB5E FC98 E8CD E0AA D460

I'm hesitant to comment further about GMPI and its chances for success or failure, because I've been too busy trying to finish RTP MIDI to keep a close eye on it. My only worry stems from a common IETF belief -- that the standards process is a great way to polish and reach consensus on a substantially complete design, but using the standards process as the vehicle to do the design is a much harder road to hoe. A good example of this is 801.11, which was an incredibly long and painful experience because many parties brought bits and pieces of wireless Ethernet to the IEEE table. Only the inherent goodness of the core idea (packet radio) kept everyone at the table to eventually produce a standard that could be interoperably deployed (801.11b, aka Wi-Fi, and its lettered follow-ons). ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------

Please share, even privately. The reason I'm keeping my mouth shut is not reluctance to offend anyone :) its because it wont help, and I dont want to be too negative about it. Standards processes that I've been exposed to generally mandate regular weekly meetings (teleconference and/or irc), with less frequent face-to-face meetings and most business is sorted out during the meetings. Email is only used for tying up loose ends and exchanging text, minuites etc. The W3C (for example) are quite stict about it - if you miss too many meetings or face-to-face's then you're not allowed to vote for the rest of the process. Sadly that wont really work for GMPI as there are too many key contributors who couldn't, or wouldn't commit to weekly meetings. I dont think the GMPI process is domed, its just likely to be slow. The recent suggestions should help. Also, the fact that theres no real pressing need for it doesnt help either - most platforms allready have OK instrument APIs and we have ALSA Seq + JACK for synths, which does work. - Steve

Maybe you can stop it from segv-ing every few hours? :-) I fixed one bug and mailed it to the author but didn't check to see if he updated it (I have 0.3). It concerned ^C behavior, e.g. ^C out of aplay or arecord with ameter as the device.

[linux-audio-dev] ALSA snd_pcm_meter_* functions?

by Erik de Castro Lopo

Hi all, Has anybody used the above ALSA functionality? The functions are defined in <alsa/pcm.h> but there doesn't seem to be any documentation nor any example programs. Do these functions work? Do they work on record? Does anyone have any example code?

[linux-audio-dev] cheesetracker / legasynth -- is it that what I think it is ??

by hexe_2003＠directbox.com

re I installed cheesetracker / legasynth on my computer and have a short question now: The instrument editor of cheesetracker, if I click arround with the buttons, and then I added it to the pattern. But cheesetracker gives out error msg's in the xterm... . Now, Can I import some sort of instrument sets into cheesetracker so that he KNOWS what to do ? And if yes, I assume these instrument structs come from legasynth ? But how can I export legasynth's instrument "files" ( if there're any) ? greetz Sascha Retzki __________________________________________________ Verpassen Sie keine eBay-Auktion und bieten Sie bequem und schnell über das Telefon mit http://www.telefonbieten.de Ihre eMails auf dem Handy lesen - ohne Zeitverlust - 24h/Tag eMail, FAX, SMS, VoiceMail mit http://www.directbox.com

[linux-audio-dev] gtk scrollbars.

by Patrick Shirkey

I've stumbled across a problem that no doubt someone has come across before. What is the recomended way to force alternate keybindings on a gtk scrollbar? Would I have to create a custom widget that is a replica is there another way? Using all the keys is a very simple way of making jackEQ truely useful in live performance. It would add functionality to the mixer in ardour too. The docs for range widgets say this: ------------ Scrollbars are not focusable, thus have no key bindings. The key bindings for the other range widgets (which are, of course, only active when the widget has focus) are do not differentiate between horizontal and vertical range widgets. All range widgets can be operated with the left, right, up and down arrow keys, as well as with the Page Up and Page Down keys. The arrows move the slider up and down by step_increment, while Page Up and Page Down move it by page_increment. The user can also move the slider all the way to one end or the other of the trough using the keyboard. This is done with the Home and End keys. ------------ -- Patrick Shirkey - Boost Hardware Ltd.
