[linux-audio-user] usb midi interface: USB Midisport Uno vs. USB Midisport Uno

by Atte André Jensen

Hi I need a basic midi interface, and I'm thinking about either the M-Audio USB Midisport Uno or the Audiotrak USB Midisport Uno. Which one should I choose (and why) for use with my debian/unstable/2.6.9 system? I would prefer an interface the works as out of the box as possible... Also are there any major disadvantages with usb interfaces, and what else would be an option in the same price range? Thanks in advance for any feedback! -- peace, love & harmony Atte http://www.atte.dk

Hi Stefano, I'm a newbie in Linux-Audio world, but maybe this can help you: using "alsamixer hw:x" where x is your card hardware id (mounting 2 cards you should have hw:0 and hw:1) be sure that integrated VIA card is setted to get clock signal from s/pdif input. If it's setted to internally generate clock signal you will have a drift between VIA and SB card, causing "clicks" you are hearing. Hope it helps! Bye Michele

[linux-audio-user] usb midi interface: USB Midisport Uno vs. USB Midisport Uno

by thewade

Deffinately do NOT choose midiman. I have a Duo and I learned that midisport does not comply to usb standards and is therefor not supported by linux. I dont know anything about Audiotrak. -thewade

[linux-audio-user] MIDI keyboard

by andrea

hi i'm trying to connect a midi keyboard Yamaha PSS-790 to the game port of my sound card SB Audigy , using a Y cable that claims to support SB. I'm running Planet on fc1, ALSA 1.0.4, rosegarden, qjctl, fluidsynth, i can actually play midi files into them. i also have a integrated soundcard with midi capabilities but it's disabled in the BIOS. here's some printout lsmod seems fine to me (snd-seq-midi etc.) aconnect -io gives [root@localhost root]# aconnect -io client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Audigy MPU-401 (UART) - Rawmidi 0' [type=kernel] 0 'Audigy MPU-401 (UART)' 32 'Audigy MPU-401 #2' client 65: 'Emu10k1 WaveTable' [type=kernel] 0 'Emu10k1 Port 0 ' 1 'Emu10k1 Port 1 ' 2 'Emu10k1 Port 2 ' 3 'Emu10k1 Port 3 ' [root@localhost root]# amidi -l Device Name hw:0,0 Audigy MPU-401 (UART) hw:0,1 Audigy MPU-401 #2 hw:0,2 Emu10k1 Synth MIDI (16 subdevices) hw:0,3 Emu10k1 Synth MIDI (16 subdevices) [root@localhost root]# cat /proc/ioports 0000-001f : dma1 0020-003f : pic1 0040-005f : timer 0060-006f : keyboard 0070-007f : rtc 0080-008f : dma page reg 00a0-00bf : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 0376-0376 : ide1 0378-037a : parport0 03c0-03df : vga+ 03f6-03f6 : ide0 03f8-03ff : serial(auto) 0cf8-0cff : PCI conf1 a000-a00f : VIA Technologies, Inc.

[linux-audio-user] HDSPmixer problem

by Kevin Ernste

Hello - I just installed a new HDSP multiface with PCI on a PlanetCCRMA/FC3 box, kernel 2.6.8.1-1.520.2vS7.ll, ALSA 1.07 (homemade rpms) and am not seeing any output levels on HDSPmixer (bottom row) despite actually hearing the signal I expect (sounds great). Modules/firmware load beautifully, I can route signal with HDSPmixer as expected, adjust levels, etc, just no visual feedback from the outputs row either with vu levels or changing peak values. Also on mixer channels that do show vu's (input and internal, top and middle rows respectively) the yellow peak indicators appear only randomly every 2-3 seconds or so, sort or popping around without any clear relation to the signal peak. Something's not right here. /sbin/lspci: 02:0d.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP (rev 0b) cat /proc/pci: Bus 2, device 13, function 0: Class 0401: PCI device 10ee:3fc5 (rev 11). IRQ 5. Master Capable. Latency=255. Non-prefetchable 32 bit memory at 0xec800000 [0xec80ffff]. "proc/interrupts says the card is on it's own interrupt, IRQ 5. Kevin

[linux-audio-user] fst - err:dosmem:setup_dos_mem

by Brad Fuller

I've installed (maybe not sucessfully) wine 20041201, fst 1.6 and jack_fst-1.2. I'm using jack-0.99 When I try and execute jack_fst such as: #jack_fst Crystal.dll I receive the following error: err:dosmem:setup_dos_mem Cannot use first megabyte for DOS address space, please report can't connect to JACK I assume that the first error message is from wine. Is that true? I haven't found a thread or docs on the wine list about this error. (I assume the 2nd error is because of the first reported error) Anyone come across this? brad -- ________________________________ Hear us online: www.Sonaural.com Brad Fuller (408) 799-6124 ** Sonaural Audio Studios ** (408) 799-6123 West San Jose (408) 799-6124 Cambrian

[linux-audio-user] recording keyboard works (e.g. rosegarden)

by Hans Fugal

I'm interested in rendering some organ works electronically. The first step of course is to get the music in the computer, e.g. in MIDI format. The piece I'm working on you can see at http://www.xmission.com/~fugalh/in_dulci_jubilo.pdf I can play this piece well enough. I don't have a MIDI pedalboard but the pedal line is easy enough to add later. But as you can see the music is in multiple voices, and I would like to instrument each voice differently. I have tried recording them one at a time, in an ensemble style, but even when I follow a metronome it ends up sounding like trash. I have decided that either I need to work on my ensemble playing or I am going about it the wrong way. Maybe I should just record the manuals and try to separate out the parts into separate tracks as a post-processing task. That's going to be a problem when I try to do something else that requires more than one manual since I only have one MIDI keyboard. Also, as much as I'd like to, I don't have the time to learn each piece I'd like to render to the point of perfect performance like I have this one. What do you all do in this situation? The same issues naturally apply to other styles of music as well, e.g. choral or orchestral. -- De gustibus non disputandum est.

[linux-audio-user] Midi app & Video app with SMPTE and/or MTC

by Brad Fuller

I need to sync video playback and midi composition. I guess I should first ask if anyone knows of midi/audio apps that have video playback builtin -- that would be preferable. I don't know of any -- and that's why I am asking this 2nd question: if anyone knows of midi composition apps that can sync using SMPTE/MTC to a video playback app -- which would also have to have SMPTE sync capabilities. This seems to be a hole in the audio caps of Linux apps. Or, am I way off base? brad -- ________________________________ Hear us online: www.Sonaural.com Brad Fuller (408) 799-6124 ** Sonaural Audio Studios ** (408) 799-6123 West San Jose (408) 799-6124 Cambrian
