[linux-audio-user] Rosegarden & ALSA Sequencer IO Ports

by Reuben Martin

I'm having trouble using timidity from within Rosegarden. I configure Rosegarden to use timidity as a soft synth, but when I try to play back I can't manage to get any sound. What is even more confusing is that when I open qjackctl's MIDI connections dialogue, I see input ports for both Rosegarden and Timidity, but no output ports for rosegarden are shown. And to make it still even more confusing is that there is a connection of some sort between the two because if I use the virtual keybd and connect it to rosegarden's in port, the output plays through timidity. 1) why is there no out port shown for Rosegarden 2) is Rosegarden using some means other than the ALSA Seq interface to connect to timidity? 3) since it is apparently connected somehow, why do I only get playback from timidity when playing something though the Rosegarden in port, while not getting any output when playing from Rosegarden itself? I've tried Muse, but it's even more trouble. It segfaults unless I use the -d option, which makes it pretty useless. Are there perhaps other midi based sequencers that work better than these that I'm not aware of? -Reuben

[linux-audio-user] How to connect MIDI

by Arno Teigseth

Hi folks I happen to be in Ecuador, and there are no [good] music shops around. Do anyone know how the 15 pin connector to the PC is connected to the two MIDI IN and MIDI OUT round 5 pin connectors? I have some idea of what pins are active (the three center pins), but no idea whatsoever on which of the 15 pins to connect. sincerely, Arno

[linux-audio-user] PCI audio interfaces

by Spencer Russell

Hey all, So I'm looking to put together a more serious recording rig, and trying to do so for under about $1500. I've got a couple ideas on how I'm going to procede, and I've been looking at a variety of PCI audio interfaces. I'm looking for 8-10 channels of analogue I/O, probably expandable with some ADAT lightpipe I/O, MIDI (although if I can't get it in the PCI card, it's not a big deal), Word clock would be nice. I don't really need onboard mic pres, as they're bound to be crap anyways, so I'd rather just get a semi-decent mixing board. Most of the cards I've been looking at have rackmountable breakout boxes, which is great, because I'm planning on rackmounting the computer anyways. The M-audio Delta 1010-LT seems to be a pretty good option, too, as it seems to have most of the functionality of the regular 1010, but about 100 cheaper on eBay. Neither have ADAT, though. The Echo Layla 24/96, also seems like a great card, and it seems to be exactly what I'm looking for, but slightly more pricey than some other options. The DSP2000 c-port seems to have everything I need, but I can't figure out how well it's supported under Linux. There're some posts on the alsa-devel archives about trying to get it working, but it's not listed on the Alsa soundcard matrix, so I'm not optimistic. Does anyone have any great or terrible things to say about any of these cards? about any other similar cards? about a completely different way of setting up such a DAW? thanks! -spencer

[linux-audio-user] FM7 ?

by Dave Phillips

Greetings, Earthlings: As a long-time fan of FM synthesis I've been wondering whether I should try getting NI's FM7 running under libfst or vstserver. I own two TX802s and am very fond of their sounds. NI's advertising makes some extraordinary claims about FM7, so I thought I'd ask here to see if anyone on this list has used it. I'm especially interested in whether anyone has actually compared it to its hardware antecedents. Anyone ? Best, dp

[linux-audio-user] Neuros

by Juhana Sadeharju

>I think the Neuros II (http://www.neurosaudio.com/) is closer to what >you need. It includes a built in microphone as well as a mic in. >Records in mp3 or WAV (up o 48KHz). USB 2.0 interface. Mine works very >well with Linux. You can get one with 256MB of memory for $140 or one >with a 20GB hard drive for $250. I would need one for making free sound effect library. Has it a stereo mic-in connector? Or stereo line-in connector for which I may find mic2line conversion cables? How do you transfer the recorded files to Linux? Is the device seen as a standard usb disk? And the audio files can be transferred as any other file? This is important if I use public PCs for emptying the recorded sounds to a web site. Neuron is only device which seems to have free (as in freedom) transfer method between the device and computer. Creatives etc. simply require one to install a special executable to your MS Windows. One may transfer audio files as regular files, but they cannot be played! Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

[linux-audio-user] RME HDSP PCMCIA Problems

by Aengus Martin

Hi, I have installed Planet CCRMA Fedora Core 1 on a Dell inspiron laptop with a RME hammerfall/multiface setup. I ran alsaconf and it set up the card with no complaints. Running hdsploader makes the 'host error' light go off on the multiface. I have recorded and played back audacity and played files with xmms. That's where the joy ends though. I have the following problems: * pd will not run - it gives this output: using non-interleaved audio input Sample width set to 4 bytes ALSA: set input channels to 14 ALSA lib pcm_hw.c:324:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed: Device or resource busy snd_pcm_hw_params (input): Device or resource busy pd: pcm.c:4973: snd_pcm_sw_params_current: Assertion `pcm->setup' failed. Pd: signal 6 Aborted * ardour won't run, output is: Ardour/GTK 0.554.0 running with libardour 0.855.0 Copyright 1999-2004 Paul Davis Ardour 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 UI configuration file /etc/ardour/ardour_ui.rc Aborted * rosegarden says audio not working * jackstart -R -d alsa -d hw -r 44100 outputs: loading driver .. apparent rate = 44100 creating alsa driver ... hw|hw|1024|2|44100|0|0|nomon|swmeter|-|32bit configuring for 44100Hz, period = 1024 frames, buffer = 2 periods .... and does not get any further. I have experienced linux alot as a user on a system someone else adminstrated, but have no experience setting up hardware or anything like that so I'm a bit clueless. Any suggestions would be much appreciated. thanks, Aengus. _________________ Aengus Martin

[linux-audio-user] Linux audio residency opportunity

by JakeHarries＠aol.com

Hi Please forward at will. -- best, Jake ------------------------------- INVITATION TO TENDER OSAudio residency [Audio artist/producer/composer in residence at Access Space, April 2005] Deadline for applications: 4th Feb 2005 Decision made and applicants informed mid Feb 2005. Fee: £3500 sterling (approx 5000 Euros @ 6th Jan 2005) Access Space, Sheffield's lowtech digital arts organisation, is currently calling for applications for a month-long, audio residency. Access Space is a free media lab in Sheffield's Cultural Industries Quarter, offering open access to people with a range of knowledge and experience of technology. We are looking for an artist to develop their project using the recycled/reclaimed "redundant" technology and open-source software available in Access Space. The aims of the residency are: 1] To offer an artist/producer/composer the chance to develop ideas using only open-source software (on the Linux operating system) in a supportive environment. 2] To offer the users of Access Space an introduction to the creative process of making new work. 3] To produce a finished piece of work (see below for further details). The Residency: The OSAudio residency will take place in April 2005 (exact times/dates to be agreed). The successful applicant will get the opportunity to work for one month (or 20-day equivalent) in Access Space's open environment, with a degree of technical support and advice available from Access Space staff. As part of the residency, the artist will run 2 workshop sessions relating to the work involved in their residency, and an informal presentation for Access Space participants and members of the public. The resident will also document their residency in the form of an online diary. Available software includes the Planet CCRMA software, with PD, Rosegarden, Ardour, Jack, Audacity, Supercollider Server etc etc. Applicants should consider that part of Access Space's ethos is to only use recycled/donated hardware. Therefore, the available hardware is a P3 800Mhz machine with Sound Blaster sound card. The majority of the work-time will be monitored using headphones, due to Access Space being a publicly accessible project. The Work: We hope to encourage a broad range of applications covering all types of audio production, be they electronica, sound art, or more traditional recording practices using open-source software. Proposals can be to produce one or more specific audio works, or for development of patches, code or software. However, the resident should aim to have a completed product within the duration of the residency. The finished work will then be available for download from the internet. The Fee: A fee of £3,500 will be offered to the successful applicant, subject to the successful completion of the residency. A small contribution towards travel and accommodation expenses may be available where appropriate. How to submit your proposal: Please email or post us a proposal, of not more than 2 sides of A4 plus your CV, including details of your experience of working with open-source music software, your reason for applying, the starting point/s for your project and how you would approach the commission. Access Space welcomes applications from all sectors of the community irrespective of age, disability, race, religion, gender or sexual orientation. Please address the following points in your application: 1 - what form the finished work would take. 2 - how you propose to engage with the participants at Access Space. 3 - how much technical support would you need. 4 - how feasible is your project in the time available. 5 - what makes using open-source software particularly appropriate for your project? For more information, questions regarding hard/software, or to mail your proposal: Access Space 1a Sidney Street Sheffield S1 4RG UK 0114 2495522 www.access-space.org access(a)access-space.org Access Space is UK registered charity no: 1103837 Access Space gratefully acknowledges financial support from the PRS Foundation, Arts Council England (Yorkshire), and Digital South Yorkshire. ---------------------------------------------------------------

[linux-audio-user] Edirol UA-25 and my USB hub

by Adrian Prantl

Hi fellow LAU'ers, I'm expieriencing strange things with my new Edirol UA-25. I am running Debian SID with a vanilla 2.6.10 kernel. The device works really fine (it has his own USB controller and is directly connected to the board) when I try to playback _or_ record @ 24Bit/48khz. But as soon as I try to do both things simultaneously (using arecord and aplay) - after about 2 seconds - I get this: Jan 9 15:06:23 vicviper kernel: hub 2-0:1.0: port 1 disabled by hub (EMI?), re- enabling... Jan 9 15:06:23 vicviper kernel: usb 2-1: USB disconnect, address 3 Jan 9 15:06:23 vicviper kernel: cannot submit datapipe for urb 0, err = -19 Jan 9 15:06:23 vicviper kernel: usb 2-1: new full speed USB device using uhci_h cd and address 4 Jan 9 15:06:26 vicviper usb.agent[5253]: snd-usb-audio: already loaded to make sure it isn't a hardware issue, I tested the device with Audacity in Windows on the same machine, and that worked just fine. Sooo. Does anyone have any idea what I could try to fix this problem? It sure does render Ardour unusable for me, which is - well - bad. thanks alot, Adrian

Hi, Try to use F3/F4 keys to view switch (Playback/Capture) - look in upper left corner in alsamixer, to see actual mode. Peter Zubaj ____________________________________ RAMMSTEIN, 22.02.2005 o 20,00, Bratislava Incheba, Info: 0904 666 363, http://www.xl.sk
