[linux-audio-user] Alsa startup booting 2.6.2

by David Baron

In reality, seems to be working just fine now. UBS works and can record notes to Rosegarden. On boot, BEFORE alsa start, restore mixer setting, etc., there is a bunch of underfind snd_..... items. Apparently harmless. I had added my alsa devices (not of the "autodetected" types) to modprobe.conf where it says to do so. I added them to the /lib/modules version as well--this may be the reason. The question is where is it correct to do so?

[linux-audio-user] wigwamjam : a genetic programming synthesiser

by Dave Griffiths

wigwamjam grows sounds using your decisions to drive the evolution of genetically programmed synth functions. wigwamjam is proof of concept for the moment, and not a fully blown audio tool yet. http://www.pawfal.org/Software/wigwamjam/ cheers, dave ................................. www.pawfal.org/nebogeo

[linux-audio-user] Re: GVox

by David Baron

No reason they should not work on Win98. Not all that different than Win95! Linux? I go my sw60xg to work following a little trick recommended by Yamaha before they had a y2k driver for this card: Use mpu401. Another possiblity would be to experiment with existing alsa serial-midi stuff. This box should be mostly sending raw midi events. How does it work, just for playing synth-guitar? Unable to afford a Roland, might be intereted in one of these. BTW, bough a "music-star" controller for $40 on ebay. Should have taken more. OK, no touch-sensitivity (did not expect it), but 10-note polyphony keyboard for that price!?! Plugs into a gameport so bought a Roland UM1 to use it through USB. Now to get the USB working again on 2.6 .... On Sunday 22 February 2004 03:36, linux-audio-user-request(a)music.columbia.edu wrote: > I bought not one...but 2 of these damn things from Ebay.

[linux-audio-user] Gvox Midi guitar...

by Russell Hanaghan

I bought not one...but 2 of these damn things from Ebay. It was a hex pickup and propietary box with RS232 midi interface to PC. They went bust a few years ago but these things are still around.The last Windblowz driver support ended in the Win 95 era. Some have reported getting them to work on Win 98. Anyway, I got 2...Right now they make great paperweights! Anyone interested in taking a stab at some linux drivers for them? If it could be done somewhat easily by someone versed in that area, it would be a possible cheap Midi guitar option. These boxes float around on Ebay for between $25.00 to $50.00. If they work even half reasonably, thats a big difference to the next midi guitar option like the Roland unit. Hell, the pickup is $200.00!! Anyway, hands up whos interested! :) I would be willing to offer up the second unit to someone who can actually get this done... R~

[linux-audio-user] Help needed to start jackd with a vxpocket

by digger vermont

Hello All, I haven't been able to get jack to start with a vxpocket V2. I'm using the commandline "jackd -d alsa -d hw:1" and getting the error: jackd 0.94.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. creating alsa driver ... hw:1|hw:1|1024|2|48000|0|0|nomon|swmeter|rt|32bit control device hw:1 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:1 for 32bit samples trying 24bit instead Couldn't open hw:1 for 24bit samples trying 16bit instead Sorry. The audio interface "hw:1" doesn't support any of the hardware sample formats that JACK's alsa-driver can use. ALSA: cannot configure capture channel cannot load driver module alsa The alsa version is 1.0.2c on a powerbook running debian testing /unstable with 2.4.24 kernel. I got the impression from some others on this list that they have it working. What's the trick? Thanks for any help, digger

[linux-audio-user] yamaha rp-u200 and jack: bad sound

by jaap

Thanks to Clemens,I have 4 channel output from my rp-u200 usb-audio "card" The problem now is bad sound,that is,lots of kind of pops or whatever it's named.Also there is sync problem,sometimes the sound is kind of slowing down. I played back sound with different applications:alsaplayer, ecasound,fluidsynth,terminatorX.Always the same result: When I run jack the sound is bad,but when do the same thing without jack running,direct by alsa there are no obvious problems(except having only 2 channels),so it can't be a hardware problem. Any ideas about the origins of this disastrous sound? I have jack 0.94.0,alsa-driver 1.0.2c,kernel 2.4.20-gentoo-r8. Thanks for help, Jaap van Geffen

[linux-audio-user] Linux midi players that don't require download of large patch or sample files??

by Ruth A. Kramer

Sorry, this is probably a very newbie question, and I haven't lurked very long or searched the archives (partly because I don't have a good idea of keywords to search for). I've used Linux for a few years, but sound isn't normally a concern. My son is trying to make the switch from Windows to Linux (and has, for some things) and now wants to play midi files. His impression is that, on Windows, sound players use synthesizer's (and "patches"/"samples") built into the sound card while on Linux those patches/samples (??) have to be downloaded and he talks about 40 MB worth of files in some cases. Maybe the difference is that we also changed computers, and his current computer has an on-board SiS 7018 sound thingie while his previous computer (IIRC) had a separate sound card, possibly with something like the Yamaha OPL xxx on it. Any light anybody can shed on this would be appreciated. (I did skim through a Linux Sound HOWTO (that was actually a little bit more like an FAQ), and saw some hints, but I really don't know how to interpret them.) Keywords to use to search the archives or Google, or pointers to simple documentation that focuses on this subject could also be helpful. No doubt what ever I learn will end up on a WikiLearn page (http://twiki.org/cgi-bin/view/Wikilearn/WebChanges). thanks, Randy Kramer

[linux-audio-user] [ANN] TAP-plugins 0.4.0

by Tom Szilagyi

Hi all, TAP-plugins 0.4.0 is just released. Check it out at: http://tap-plugins.sf.net New plugins: * TAP Pitch Shifter Gives you the opportunity to change the pitch of individual tracks or full mixes, in the range of plus/minus one octave. Audio length (tempo) is not affected by this plugin, since audio is completely resampled. * TAP Rotary Speaker Simulates the sound of rotating speakers. Two pairs of rotating speakers are simulated, each pair fixed on a vertical axis, with their horns spreading the sound in opposite directions. * TAP Vibrato Modulates the pitch of its input signal with a low-frequency sinusoidal signal. It is useful for guitar and synth tracks, and it can also come handy if a strange effect is needed. Bugfixes: * Fixed crashing bug in TAP Reverberator (this bug appeared with hosts that call activate() before connect_port()). * Fixed lock-up bug in TAP DeEsser (the bug appeared when an input sample had +/- INF value). * Various smaller bugfixes (almost all plugins locked up when control input values of +/- INF were appiled). A recommended upgrade ;-) Enjoy, Tom
