But still no sound. Hrm. You've tried other programs to send the MIDI sequence to the synth (e.g. aplaymidi), right? (just to make sure that it's not an issue with Rosegarden) Alternately, you've successfully played the MIDI sequence through a softsynth like timidity, right? (to point the finger directly at getting the synth working) I think I remember reading that you'd done so. Right? If so, I'm at a bit of a loss. I never had any problem getting this stuff to work. Once upon a time, about a year and a half ago, I wrote up a brief HOWTO-ish document for MIDI on Linux, but it's currently on a disk attached to a machine that won't boot. The only other thing I can think of right now: I believe I remember reading that you'd played around with all the controls in alsamixer that seemed relevant; you may want to revisit that again. I haven't seen how the emu10k1 looks in recent versions of alsa/alsamixer, but the volume control for the output of the wavetable synth used to have the singularly unhelpful title of "Music" in alsamixer. You might play around there. Or perhaps steal the mixer settings from someone who's got it working, and see if that helps. > It's > probably something ridiculously simple, since I'm new to this... S'ok. You're right that it usually is something simple, but it never seems that way until *after* the problem is solved, when it's easy to call it that! -c

[linux-audio-user] JAD kernel released

by Michael Bohle

The JackLab team proudly announcing their first SuSE flavoured full-preemt lowlatency RT kernel 2.6.15 release this weekend. For tester this audio kernel will be available now in our APT-repository at gwdg.de. This is an important milestone for the project on our way to the openSUSE based JackLab Audio Distribution. Oliver Bengs (Appleonkel) has created this openSUSE Linux 10.0 compatible kernel.rpm. We decided to release a seperate rpm with realtime linux security management module (rt-lsm) as a optional opportunity for user realtime capabilities. A step by step installation guide can be found in the user support forum http://jacklab.net/phpBB2/viewtopic.php?t=29 Michael Project manager

[linux-audio-user] Edirol UA 1EX @ 44.1kHz

by Christoph Eckert

Hi folks, a friend of mine has a collection of mp3 files which all are based on 44.1kHz. Using a soundcard which only supports 48kHz makes it necessary to resample the audio material before outputting it to the card/speakers. To avoid the resampling, he's looking for an USB audio card which runs well on Linux (preferably with the snd_usb_audio-module) and natively supports 44.1kHz in hardware. One choice could be the Edirol UA 1EX, but I haven't found any resource which clearly states that it is running well on Linux, even at 44.1kHz. On http://www.roland.com/products/en/UA-1EX/ I can read »Supports both advanced and OS-standard drivers (Win/ Mac OS X), selected with ADVANCED DRIVER.« but I also see http://www.linux-m32r.org/lxr/http/source/sound/usb/usbquirks.h /* TODO: add Edirol UA-1EX support */ Can anyone give me a wee small hint whether the device works or not? If so, any experiences with material at 44.1kHz? Best regards ce

[linux-audio-user] RME Multiface - MIDI

by Edwin Peer

Hello all, Can anyone confirm whether or not the hardware MIDI ports of the RME Multiface are supported by ALSA? According to the alsa-project web site, the Multiface does not support [MIDIio], however, that same site also shows that the Digi32 and Digi96 do not support [MIDIio], which contradicts what I've read on various mailing lists about ALSA's MIDI support for the Digi32/96. I'm trying to get the MIDI ports of a Multiface working (to get Rosegarden talking to an external keyboard), but so far have had no success. Any ideas? Pointers to relevant documentation? - Edwin -- #include http://www.peer.co.za/~espeer/disclaimer.html

[linux-audio-user] MidiSport 4x4 on SuSE 10

by christian bunge

Hi all, I have a problem to install the firmware-loader-0.5 for the MidiSport 4x4 I have found a hint at http://sourceforge.net/projects/usb-midi-fw/ that there is a problme with udev this is what I did: First I installed de firmware-loader-0.5 Then I created a new rule file in /etc/udev/rules.d named 13-Midisport4x4.rules with this only line. SUBSYSTEM=="usb", ACTION=="add", SYSFS{idProduct}=="1020", SYSFS{idVendor}=="0763" , RUN+="/sbin/fxload -s /usr/share/usb/midisport/MidiSportLoader.ihx -I /usr/share/usb/midisport/MidiSport4x4.ihx" now the MidiSport 4x4 is detectet, but the lights are flashing up and down. I get a kernel massage linux kernel: usb 1-1:device descriptor read/64, error -71 thanks for help christian

[linux-audio-user] Designing system for 'virtual' whole house audiosystem that deals with all kinds of audio sources ?

by Robert Rozman

Hi, I'm designing integrated home automation/entertainment system based on Linux and other open source apps. I have several possible sound sources (like Festival as speech synthesis, music players, VOIP or ordinary telephony applications, intercom) and several sound destinations (rooms in my house - can be either remote desktop running some network audio client or separate output on multichannel local audio card). Now I'd like to implement 'virtual' audio router/mixer in software that can be dynamically controlled from other program language (Perl is preffered in my case). I'd need to combine several audio sources to each sound destination (like big software switching/mixing/routing black box), dynamically change volumes, add/remove chains etc... I'd like to deal with all this with Ecasound (it can be controlled from Perl) - or should I use some other program ? I'm thinking of using Alsaplayers as music/wav players (they have software volume control) , Jack (as sound servers) and Ecasound (for routing, mixing) .... Some possible scenarions: - when internet voice call comes in, then I connect to certain channel on audio card for certain room (route two way audio stream that comes from Internet to certain audio destination/source) - when watching TV (sound going to some audio card output), speech synthesis would like to announce something (I'd like to volume down TV audio and mix speech, and then go with TV volume to normal level) - from one room I'd like to talk to another... If I think ideally - best would be to have range of "virtual" sound destinations, that could be dinamically routed,mixed to physical devices. As far as my novice knowledge goes I was thinking of using Alsaplayers as music/wav players (they have software volume control) , Festival as speech synthesis, some softphone for IP telephony (that could output to ecasound or Jack) and every other valuable suggestion for software package I get. I don't know much of Jack, maybe its also part of solution.... Any other advice in apps to use, more info or any other opinion would be more than grateful. Also if anyone made some effort or thinking in this direction - it'll be of great help... Thanks in advance, Rob.

I've also put > 'snd-usb-audio' on the blacklist of hotplug, because > hotplug makes some real trouble with USB audio devices. I had exactly the same problem when updating Gentoo recently. Hans Fugal kindly tried to help me on this list on 6 Dec 2005, and sent me this informative link: http://sourceforge.net/tracker/index.php?func=detail&aid=1353514&group_id=8… However, that didn't fix it for me. Now, I have an ugly workaround in place: a little script that gets run by /etc/conf.d/local.start, which contains the following: #! /bin/bash modprobe snd-usb-audio cd /usr/share/usb/midisport fxload -D /proc/bus/usb/004/003 MidiSportLoader.ihx -I \ MidiSport2x2.ihx exit This works, provided that the MidiSport is always at the same USB bus address; in your case, you will have to change the /004/003 to /002/003. Hope that helps. I'm interested by your comment "hotplug makes some real trouble with USB audio devices". I'm having trouble getting the audio side of my Novation Speedio (a USB audio and MIDI interface) to work properly (as per previous posts on this list) - could this be related? If so, what do I do to run it without hotplug? Just one more comment while I'm mailing the list: if anyone uses the Proteus 2000 (a hardware synth), you might be interested in having a copy of a spreadsheet I've prepared, which has descriptions of all the drums and percussion sounds in the ROM it ships with. Let me know. Peter C

[linux-audio-user] Slightly OT: Jack-aware applications on OSX

by Adrian Prantl

Hello, I wonder if there is a list of jack-aware applications that also work on MacOS X? So far I'm a happy user of Ardour and Hydrogen, but I'm missing a MIDI Sequencer type app, like Seq24 or Muse. cheers, Adrian
