[linux-audio-user] St-audio C-port 2000

by Aleksandr Koltsoff

Hello Found some emails from 2004 about the status of this card/box-combo in linux. Does anyone have any updated info on the status? With ubuntu5.04/alsa and envy24control I can do data output trough the box, but fail to get any input from the box. Based on documentation from 2002 (st-audio one), seems that the inputs need to be "enabled" by their software (routing?) that will turn on a LED above a pair of lines. I haven't managed to do this by any means. The PCI card is interestingly enough identified by lspci as "VIA Tech Inc ICE1712 [Envy24]" although I don't know why it's VIA. Maybe they share the PCI vendor and subvendor id, go figure. I have some experience in driver and software programming and am willing to help if anyone needs it. I looked the envy24control code over, but the only feeling that I get currently is that my head will soon explode. Barring getting c-port working in Linux, can anyone recommend any comparable gear that works in Linux (USB2/firewire preferred)? Multitrack audio, inputs more important than outputs (unbalanced ok). Thank you for your time and hope to hear from you soon. ak.

[linux-audio-user] RLIMITS and /dev/rtc for MusE

by Thomas Kuther

Hello dear audio users! Recently i upgraded to a 2.6.13-rc6 kernel and since then i wasn't able to use realtime-lsm anymore (error when loading the module). Now i switched to rt RLIMITS. Therefore i had to bring back PAM on my nice PAM-free system (i don't like PAM i have to admit). Now i have some problems with it: i can't start MusE sequencer anymore as user because: ------------ MusE: watchdog process 18591 _NOT_ running SCHED_FIFO cannot set ticks 1024 on /dev/rtc: Permission denied precise timer not available ------------ With realtime-lsm everything worked fine. I think I've set up pam-login and /etc/security/limits.conf correctly. At least i can start jackd as user with RT privileges, so I assume it's working. Could it be that i forgot something? The rights on /dev/rtc never changed, so i think it's a) wrong setup from my side, or b) a malfunctioning RLIMITS. I don't want to change the permissions for rtc as it worked fine with rt-lsm. Any help would be appretiated. Regards Tom

[linux-audio-user] VST Plugins Revisited (Again)

by davidrclark＠earthlink.net

Brad mentioned VST Plugins in an earlier post. I've had no luck at all with any of the Linux methods. I have had perfect success with a "free" version of Muzsys that Computer Music Magazine had on one of their CD's: CompMuzsys. This works flawlessly under WINE. It is an "entry level" piece of software, but does have fairly good mixing. It has lots of latency and only primitive MIDI editing. But if I'm in Linux and want to do something quickly without rebooting, this is the way I go. CompMuzsys is the only Windows audio program that I have seen that works under Linux just like it does under Windows. I have dozens of VST and VSTi Plugins, and every single one of them works. This shows that IT IS POSSIBLE. I find it amusing that to run VST or VSTi plugins, I had to install a piece of Windows software. It makes me wonder if the future of music production using GNU/Linux is to run (entry level) Windows audio software under WINE.

[linux-audio-user] Suggested laser printer for score printing?

by Mr. Spock

Hello, [I've just delurked and re-enabled Mail Delivery for this list for a while to ask this question; there's usually too much traffic for me to keep up nowadays, sadly.] I Googled and looked at the archives but there's not much here about printing music notation. I'm needing to buy a printer that will be ideal for score printing and also plays well with Debian/DeMuDi. Since I don't really need colour, I'd prefer a laser printer. I'll stick with black+white A4 for now for cost reasons - I'm looking to spend about 200-300 UK pounds (about $300-500) max. I've not yet used Lilypond or any other scoring software, but believe that Postscript is a major plus. I know that Ghostscript exists to convert Postscript documents, but figure that if my printer natively understands PS it will be quicker and save processor time. Is Postscript Level 3 required, or will Level 2 suffice? PJL? PCL5? I also want a networkable one to share over my (wired) LAN. I've looked at the very informative pages about Linux Printing: http://www.linuxprinting.org/suggested.html ...and am considering getting a Kyocera Mita FS-920, FS-1010N or FS1020 or maybe something else by another penguin-loving company. Since I do have a fondness for old lo-tech gear, I did entertain ideas about a refurbished HP LaserJet 4 or 5 (fond memories from college days) after the high praise these old tanks got on Slashdot a while ago, but am thinking they may be a bit slow/tired compared to modern kit. My main considerations are reliability, build-quality, cost-per-page, speed and looks. I won't be printing reams and reams, and I can always manually re-enter pages to do duplex (both sides) printing. Sorry if this seems Off-Topic, but I wanted to check firstly that a Postscript mono-laser is a good choice for music. If necessary I'll take the discussion elsewhere to ask about specific models, unless anyone here has any good recommendations/horror stories to share. Thanks for your suggestions, -- Malcolm Smith http://www.canopus22.demon.co.uk/

[linux-audio-user] usb-audio enquiries

by pX

Hi there I've been reading the list for some weeks now, but did not see anything related to USB, so I'm just asking : Is *my* setup "viable" ? Athlon2000XP TBird 256Mg RAM (I know, I know:( ) Novation X-Station 25, latest firmware (1.3) Agnula/Demudi 1.2.1b Gnome Hydrogen => Jack => Ardour And, heck, *everything is working smoothly* (Ardour is amazing, really amazing), exept for one detail : The monitoring is crackling, buzzing, no wait, only crackling. But when I look at the waveform, in Ardour, it looks pristine, I'm pretty sure that if the cracks heard were actually recorded, I'd see them on the waveform, right ? I think I tried everything that jack allows in terms of bitrate, and frequency. Everything is package-based, and being the lamer that I am, I'd really like to keep it this way. To put it another way : I never got any tarball to compile properly, even the slightest windowmaker applet. Basically, what I want is multiple (up to 16 I'd say) audio tracks, and hydrogen sync'ed to it. Is that even english ? I hope I'm making sense, please excuse me if I don't. What I expect from this quistion is something along the lines of : # Nobody ever had satisfactory result with USB-Audio in Linux (ouch) # Get at least the double more RAM, then come back # Have you tried <this> Thank you very much, feel free to redirect me to the archived threads if this very subjet has been addressed before, and again, please, forgive my bad english, I'm really doing my best. Keep stompin' -philippe -- <-------------- www.halluci.net -------------->

Re: [linux-audio-user] midi and ecasound

> $ aseqdump -p 80:1 > Waiting for data.

Wait a minute, aseqdump shows almost all the information you need to fill the ecasound parameters properly. After the "Control change" text, you find three columns: * First column (under "Ch") is the channel number, starting from 0. MIDI channels are usually numbered from 1 thru 16, but this program shows it starting from 0, and up to 15, so you need to add 1 to the channel number when using it on Ecasound. * Next one, under "_Data_", is the controller number. MIDI controllers range goes from 0 to 127. Each controller number means something, where 1 means "modulation", 7="volume",... * Last column, also under "_Data_", is the controller value, or amount. This value changes while you move the fader, stick, or button on your MIDI device. [...] (talking about gmidimon...) > it gives me this information : > > Status Chan Data1 Data2 time > Control(176) 0 1 54 1123881037 > > I suspect I can use this information in ecasound so when I run ecasound > like that : > > # ecasound \ > > > -G:jack,ecasound,notransport \ > > -Md:rawmidi,/dev/snd/midiC2D0 \ > > -a:6 -i:jack \ > > -ea:1000 -km:1,0,1000,176,0 -o:jack Ecasound syntax for MIDI continuous controllers is: -km:fx-param,start-value,end-value,controller,channel The number(176) displayed by gmidimon is the decimal value of the status byte for the controller message (0xB0 in hex) and means that it is just a controller message on channel 0. This program also displays MIDI channels starting from 0 instead of 1. The 'Data1' column shows the controller number (1), and 'Data2' shows the controller amount (54). Your command line could be: "-km:1,0,1000,1,1" > What am I doing wrong ? And why the midi monitoring is so erratic ? Yes, you are being a bit erratic switching from one program to another without stopping to learn what means the output of each one. Regards, Pedro

Re: [linux-audio-user] Suggested laser printer for score printing?

by Gavin Stevens

Hi Malcolm, I use an HP LaserJet 4000 N for printing & I am always pleased with the quality. Not bad for £50 s/h a couple of years ago. Even better, I have never had to do anything regarding setting it up from within the system. Both Debian & Ubuntu seemed to recognise it instantly during installation & it is just always there, ready to go. I think that most straightforward laser printers should be fine. Personally, I would recommend HP based on experience, but if looking to buy second hand, avoid the HP 4050 printer/fax - I do remember from reading at Linux Printing that this will not work at all with Linux.

[linux-audio-user] Soundcard question, audiophile 192 and usb

by Allan Graves

Anyone using the audiophile 192 by m-audio? I see that the audiophile 2496 is supported, but alsa doesn't list the audiophile 192 as anything. Have people gotten usb sound cards to work with low latencies? The ardour page says to not use them, but I seem to recall some people on this list using them with success for realtime situations.... Also, anyone have any thoughts on using total software mixing vs. hardware mixing for computer based recording, live play, etc? -- --- Allan Graves I came into this world with nothing, and I have most of it left. Madness has its toll. Exact change only please.
