Hi LAU! My band, which is about to change name but currently has a few rough demos up here: http://www.myspace.com/iamtenninja Is looking for an experienced produced to mix, tweak and generally and improve the sound of our Ardour sessions. We're not signed and nor can we afford serious money but we thought it would be a good idea to see who may be up for working with us on here- the idea being that the first track would be worked on for (next to) nothing and then if we like what you do we can come to an agreement for reasonable payment for subsequent tracks. Please respond to my email or otherwise get in touch with us off list please, Thanks! Dan

Wish I could help Allcoms, but unfortunately I'm sort of "between studios" at the moment -- most of my audio gear is lent to a friend who's working on an album with his band. If you're still looking for help in about 6 months or a year, give me a shout, I'd be glad to lend an ear. :) (unintentional rhyme, I promise) -sean > > Best, > > Jeremy > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user(a)lists.linuxaudio.org > http://lists.linuxaudio.org/listinfo/linux-audio-user

Re: [LAU] can't get virmidi to work with 11.04 Natty

In Windows, MIDI devices drivers have ports that programs can connect to, while programs cannot create ports. Therefore, if you want to connect two programs, you have to use a tool like Midi Yoke that creates a virtual device. In Linux, both drivers and programs can create ports, and synthesizers typically do create such ports so that you can connect directly to them. Wine doesn't do this for Windows applications, so you have to use a "Through" port, which behaves like a MIDI through port in Midi Yoke. > The midi interfaces that looked useful that I can see in BIAB and Reaper are > the virmidi ones. Tell BiaB to play to the Through port, and tell Reaper to record from the Through port. Regards, Clemens

[LAA] [ANNOUNCE] aj-snapshot-0.9.5 has been released

by Lieven Moors

Hi all, I'm proud to announce another release of aj-snapshot. aj-snapshot is a command line utility to store/restore ALSA and/or JACK connections to/from an XML file This release adds one major feature, which is that aj-snapshot can now run in daemon mode. In this mode, aj-snapshot will restore ALSA and/or JACK connections automatically when clients become available. You can find more info on this feature in the README file, and on the website (sorry, no manpage yet). The addition of this functionality was mostly done by Jari Suominen, and I am very grateful for his help on improving aj-snapshot. As always, there must be bugs, and I would be very glad if you would report them on the sourceforge site. direct download: http://sourceforge.net/projects/aj-snapshot/files/aj-snapshot-0.9.5.tar.bz2… aj-snapshot website: http://aj-snapshot.sourceforge.net/ bug tracker: http://sourceforge.net/tracker/?group_id=311291&atid=1310488 feature requests: http://sourceforge.net/tracker/?group_id=311291&atid=1310491 to clone the git repository: git clone git://gitorious.org/aj-snapshot/aj-snapshot.git

can't get virmidi to work with 11.04 Natty

by Tony Austin

I had virmidi working fine with 10.4 Lucid but since updating to 11.04 Natty I cannot make it work. I have followed the HOWTO [url] http://tldp.org/HOWTO/MIDI-HOWTO-10.html[/url] which is the best and about the only reference I can find. It's out of date but I've done my best with it. I have installed the standard 11.04 installation as an update from 10.04 - generally everything is fine, just this one problem. My installation includes:- paman - Pulse Audio Manager pulseaudio pulseaudio-module-jack qjackctl jackd1 (I can't get jackd2 to work) aconnectgui - midi router vmpk - virtual midi piano keyboard timidity - midi synthesizer Here's what I've done:- [CODE]/etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line.

I can use either qjackctl or aconnectgui to make the virtual patches. I test thus:- 1. start timidity 2. launch vmpk virtual keyboard 3. edit connections in vmpk to send output to a timidity port 4. play the keyboard and I can hear the piano 5. edit connections in vmpk to send output to virmidi port 6. change the connections in aconnectgui [IMG] http://www.wikiwhatever.com/aconnectgui-1.jpg[/IMG][IMG]http://www.wikiwhat… 7. play the keyboard and there is no sound 8. conclusion: virmidi is not working. If anyone can shed any light on this I would be grateful. Tony

[OT] a band video

by Dave Phillips

Greetings, A video from a recent performance of my band playing one of my songs: http://www.youtube.com/watch?v=GqgDNiFXxPI My brother shot it with a new recorder, he doesn't quite have the audio settings optimized, but it's the best vid we've got of the band so far. Just so I wouldn't be utterly OT I did the titles and rendering with the latest Kdenlive. :) Best, dp

Looking for testers for open source speech-based adventure game

by Jeremy Salwen

Hi All, I'm working on an adventure game, which is entirely speech based. It is similar to a text-based adventure game, except you speak and hear the text, rather than typing and reading it. I am looking for people to test it and give me suggestions for improvement. The game itself is just a retrofitted version of the Colossal Cave Adventure game (known to some as simply "adventure"), and it uses CMU PocketSphinx for speech recognition, and Festival for speech production. It was originally a Uni project. If playing this sort of game, and giving me feedback on it seems interesting to you, please let me know. If you just want to download the source right away, the link is here<https://github.com/downloads/jeremysalwen/adventure-sphinx/adventure_sphinx…>. However, I might warn you that the game is a bit rough to play if you are not familiar with it (which is precisely why I am looking for feedback on ways to improve it). If you've played the game, please let me know: 1. What you tried to do that it wouldn't allow you to. 2. What phrasings didn't work for commands which you thought should have. 3. What it had a hard time recognizing. 4. Anything it recognized as a command that doesn't make syntactical sense. If you're getting really bad speech recognition results, remember to try to adjust your microphone and volume settings. Thanks a lot, Jeremy Salwen

Please help me with Timidity

by Fernando Araujo Martiniano

Hi. Have anyone of you ever used Timidity Win32GUI, that is the .exe gui for windows? If not you may download it from http://timidity.s11.xrea.com/index.en.html and run it under wine, that it works right. What I have in mind here is that I didn't find all the options that windows gui has in timidity gui's for linux nor in command line. For example, in win32gui there's a menu "config" and an option "preference". There you may check boxes that will allow timidity to recognize or not reverb, attack, chorus and many other specifications in the midi file. I know that if we launch timidity from command line on linux we may specify these paramenters for all files, but I what I need is a way to make timidity on linux recognize how these parameters are set and/or changed in a midi file while playing it. The reason is that I use timidity as output for rosegarden. While typing in rosegarden I insert in the file changes for attack, reverb, brightness and so on. But playing it in rosegarden with timidity as output or exporting it as midi and playing in timidity through linux gui's brings no effect change. However if I take the midi file and play it on windows gui all effects are recognized! I have noted that win32gui generates a .ini file where these configurations are stored but in linux I didn't find anything similar. Can anyone help me, please, to make timidity on çlinux recognize effects changes? Thank you. Fernando Martin

Question about rtirq name list

by Diego Simak

Hi List, I have 3 soundcards on my laptop, which the USB-Audio is the one that I use for audio: cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xda100000 irq 49 1 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xda010000 irq 50 2 [CODEC ]: USB-Audio - USB Audio CODEC Burr-Brown from TI USB Audio CODEC at usb-0000:00:1a.1-1, full speed The other ones (Intel at IRQ49 and HDMI at IRQ50) are both named as "hda_intel" in /proc/interrupts cat /proc/interrupts CPU0 CPU1 0: 2154514 2010267 IO-APIC-edge timer 1: 5855 3 IO-APIC-edge i8042 8: 0 1 IO-APIC-edge rtc0 9: 3021 126 IO-APIC-fasteoi acpi 12: 79 168302 IO-APIC-edge i8042 16: 251 150500 IO-APIC-fasteoi uhci_hcd:usb3, uhci_hcd:usb7, jmb38x_ms:slot0, mmc0, eth1 18: 0 0 IO-APIC-fasteoi uhci_hcd:usb8 19: 0 3 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb6 20: 16 14 IO-APIC-fasteoi ehci_hcd:usb2, uhci_hcd:usb5 21: 5123 1 IO-APIC-fasteoi uhci_hcd:usb4 46: 0 0 PCI-MSI-edge eth0 47: 50155 2690 PCI-MSI-edge ahci 48: 188 4372 PCI-MSI-edge radeon 49: 332 226 PCI-MSI-edge hda_intel 50: 138 252 PCI-MSI-edge hda_intel NMI: 0 0 Non-maskable interrupts LOC: 1223006 1601379 Local timer interrupts SPU: 0 0 Spurious interrupts PMI: 0 0 Performance monitoring interrupts IWI: 0 0 IRQ work interrupts RES: 16171 8941 Rescheduling interrupts CAL: 5353 4038 Function call interrupts TLB: 2520 2658 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts MCE: 0 0 Machine check exceptions MCP: 18 18 Machine check polls So my question is: How to name the service name in the RTIRQ_NAME_LIST in rtirq.conf if both cards are named as "hda_intel"? I think that a solution will be to blacklist the HDA ATI HDMI, but I would like to know if there is some other way. Thank you very much. Diego

Akai APC controllers - Experiences?

by Harry van Haaren

Hey All, I'm currently thinking about getting a "grid" style controller, something to control a live performance. Looking at the options I see the Novation Launchpad <http://www.novationmusic.com/products/midi_controllers/launchpad>, Akai APC 20 <http://www.akaipro.com/apc20>, Akai APC 40<http://www.akaipro.com/apc40> . I'm aware that the launchpad has been "converted" to linux by the great work of NightMorph (see here <https://github.com/nightmorph/launchpad>) A bit of googling / forum reading didn't get me many results on if the APC line works with Linux / if its a standard MIDI device? Very instrested in peoples experiences! Cheers, -Harry
