[linux-audio-user] Setting OSS emulations using .soundrc?

by David Baron

I have three "cards" 1. An ens1371 -- oldie but goodie fished from the can (as my dman2044 has no alsa support). 2. A Yamaha sw60xg. Midi sound generator, run through snd-mpu401 (Yamaha recommended such in w2k before they had a real driver). 3. A Roland um-1 USB MIDI interface. Applications that let me choose my routings work fine. Jack is great. However, many OSS oriented apps simply default to the /dev/??0 as default. In my set up, audio plays but of course, MIDI does not. Nor can I get MIDI input. How might I set things up so that the default output /dev/midi0 references the Yamaha, now referenced in /dev/midi1, for instance and the input references the um-1, now /dev/midi2 ??

[linux-audio-user] Specimen and 64 bits software

by yves_p＠nnx.com

Hello. I'm about to switch from Debian Sid 32 bits to Gentoo 64 bits. I have noticed ( http://packages.gentoo.org/search/?sstring=specimen ) that Specimen isn't provided as a package in Gentoo 64 bits. So I have two questions : - Does the source code of Specimen compile and permits a normally usable Specimen under a 64 Bits OS ? (and, if it's the case, does anybody know why there's no gentoo package ? Lack of interest from any developper or something, as quite any other audio apps seems to be avalaible under gentoo ?). - If I setup a 32 bits chroot under Gentoo 64 bits as it's documented here : ( http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=2 ), will Specimen be usable just as a normal jackd-enabled software, with jackd running in the 64 bits environment ? More generally, when encountering an audio software which cannot run in 64 bits, how does it work with 64 bits jackd ? Thanks in advance for any enlightenment :). Cheers, Y.

[linux-audio-user] Re: [Announce] MusE 0.8 released

by David Baron

1. Libsndfile-dev debian package was defective. Hand edited the pkconfig file. Latest and greatest on Debian may be OK. 2. Inserting the brackets in that switch statement enables that to compile. 3. rack.cpp reads a node.h file. There is one such file in the muse directories and one such file in the kde/qt3 directories. The latter was being used which was a no go. Made a more specific path in rack.cpp. 0.8 runs quite nicely :-)

Re: [linux-audio-user] Blue snoball USB mic

by lee＠rockingtiger.com

I have used Jack with two audio devices, a usb device for input and a built in laptop device for playback. There were audible dropouts, but that is because the built in device is poorly made. So using my past experience, it would be possible to use a usb mic as input and a second usb device for output, creating a self contained portable studio. -lee -----Original Message----- From: Lars Luthman <larsl(a)users.sourceforge.net> Subj: Re: [linux-audio-user] Blue snoball USB mic Date: Thu Mar 16, 2006 2:30 Size: 983 bytes To: A list for linux audio users <linux-audio-user(a)music.columbia.edu> On Thu, 2006-03-16 at 02:02 -0500, Lee A.

Remember that JACK can only handle one audio device, so it's probably not completely trivial to record from an USB microphone (which is a separate audio device) and for example output to another soundcard using JACK. -- Lars Luthman PGP key: http://www.student.nada.kth.se/~d00-llu/pgp_key.php Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E --- message truncated ---

I always found the ALSA docs a bit confusing with regards to midi but with the help of someone off-list I sorted it out. For anyone else who has alsa/midi/puredata problems, remember to start pd with -alsamidi and then run aconnect or whatever to connect yr midi devices to puredata's midi in ports.

[linux-audio-user] uc33 usb midi + midi gear

by Chris McCormick

Hi All, I am having a perplexing problem with some midi gear. I have a TR-505 drum machine's midi out connected via midi cable to a uc33 midi controller's midi in. If I cat /dev/snd/midiC1D0 I get characters printing out whenever i turn the knobs on the uc33. If I start a beat on the TR-505 I get no characters. If I run puredata I get data from the uc33 coming in as per normal. but then catting /dev/snd/midiC1D0 does not print characters when I turn the knobs on the uc33. If I start a beat on the TR-505 whilst puredata is running I see it output characters in time to the beat. So basically while puredata is not running I can see data coming from the uc33 but not the TR-505. While puredata is running it reads from the uc33 but not the TR-505 and on the command line I can see data from the TR-505 but not the uc33. Anyone know what is going on? Best regards, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

[linux-audio-user] Using > 1 audio device

by david golightly

Hello everyone, Sorry if this seems like a bit of a daft question, but I'm happily running Ubuntu 2.6.15-4rt, alsa, jack etc. on my Acer Aspire laptop, and have had success using either the built-in laptop sound card or a USB-audio device (in my case Griffin iMic), either will work fine, but my question is, is there some way, using Alsa/Jack, to use both at the same time? As far as I can tell, having read through the docs on alsa & jack, it's either/or, but I'm sure I'm not the first to try this... having 2 separate stereo audio outs would be phenomenal, if it works! Thanks in advance, David

[linux-audio-user] ardour replacement for sonar?

by thewade

Hello all, I am loving ardour! I am trying to figure out how much of a replacement for Cakewalk Sonar Ardour is, and I am hoping you can help me (BTW I am not really using MIDI at all, just wav files). 1. Can you apply enveloped effects to a track within ardour (without bouncing to a track, applying your effects in audacity or something, then reimporting and crossfading)? 2. When I try to draw a volume envelope I can only add new nodes, I can't seem to just move existing ones. Thank you all for your help, -wade

[linux-audio-user] mono to stereo input in ALSA

by Ken Schutte

Hi, When I play a mono source into line-in, is there a way to have ALSA map this to left and right channels, so that it's as if I had a stereo input? With a guitar input and wearing headphones, it's pretty annoying to hear only on the left. Thanks.
