It's the combination of the mobo, MIDI device and software settings. Using e.g. HPET for the sequencer timer could improve this issue. Regarding to Linux drivers for the MIDI device, Envy24 cards are supported. Sometimes there's the need to do some editing to get audio working, when pulseaudio is installed, but this has got no impact to MIDI. I own 2 TerraTec EWX 24/96 PCI cards for MIDI usage only + a card from another vendor PCIe for MIDI and audio. The TerraTec cards have less jitter and as mentioned before, pulseaudio isn't an issue for MIDI only. I bought one of my TerraTec cards for less than 30.00 EUR at Ebay. So +1 for Envy24 cards for MIDI only. Happy new year to everyone! Ralf -- FWIW I also own a Swissonic USB MIDI. On my machine jitter is that low, that it "should" be inaudible. I anyway advice against USB devices.

Update: ALSA Looback - Jack bridge

by James Warden

Hello, I have found the time to update my old WIKI page describing how one can use the ALSA Loopback device to bridge ALSA only apps to Jack. I have added : - a little information here and there - detailed some asoundrc examples - added an alternative setup which uses a mix of the Loopback device (for ALSA playback) and input of a second soundcard (onboard chip) for ALSA capture. Read on if you are curious or want to tailor your asoundrc in the case that you are using this trick. Cheers! J.

Shortly after I posted to this list yesterday I realised I was (amazingly) being lazier than normal and indeed it only took me 10m to write just the script I required which I have now shared with the Linuxsampler community here: http://bb.linuxsampler.org/viewtopic.php?f=7&t=667&sid=cfbd2bff56d89d82c678… Just in case that board goes bye-bye the script is short enough to paste in this message too: -------------------------------------------------- #!/bin/bash # makesfz.sh reads all wav files in the current dir and creates an .sfz file # for use by Linuxsampler named after the folder containing them. # by Dan MacDonald 2012 key=0 rm -f ${PWD##*/}.sfz for wavs in *.wav do echo "<region>" >> ${PWD##*/}.sfz echo "sample=$wavs" >> ${PWD##*/}.sfz echo "key=$key" >> ${PWD##*/}.sfz echo "lovel=0 hivel=127" >> ${PWD##*/}.sfz echo "" >> ${PWD##*/}.sfz key=$(($key+1)) done

Yoshimi 0.060.11

by Jeremy Jongepier

Dear all, I've just uploaded a new release of Yoshimi to SourceForge. This is basically a maintenance release as Yoshimi fails to build with the latest version of FLTK (1.3). Thanks to Frank Kober for pointing this out and for providing a patch. I've also applied the Legato pedal patch from Kristian Amlie. This patch is so simple and clean, you wonder why it wasn't implemented earlier. Thanks Kristian! http://sourceforge.net/projects/yoshimi/files/0.060/yoshimi-0.060.11.tar.bz2 And a happy New Year!

New arrangement and mix

by Folderol

... of a 3 year old tune. The original is: http://www.musically.me.uk/music/In_Search_Of_The_Lost_Tribes.mp3 and the latest version is: http://soundcloud.com/soft-sounds/in-search-of-the-lost-tribes/download This is not fixed yet. I'm hoping for suggestions. That's also why I've put up just mp3s as I'm casting a wide net :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Have some free music!

by Aurélien Leblond

>Time for some harmless selfpromosion ;) five new songs since I last posted. > >http://sharpattack.bandcamp.com/ Very nice! I really like the drums! A guess it's a "real" drummer? You're not using a programmed drummachine like Hydrogen (I still ask the question because the answer could be surprising!) Aurélien

USB-Audio and XHCI (USB 3)

by Aurélien Leblond

Hi everyone, I was wondering if anyone managed to run a USB 2 soundcard on a USB3 (XHCI) port? I'm running the kernel 3.2 rc7. With the M-Audio Fast Track Ultra (USB 2): The output of dmesg is this: [ 475.094595] usb 3-1: new high-speed USB device number 2 using xhci_hcd [ 475.108605] usb 3-1: config 1 interface 3 altsetting 0 bulk endpoint 0x7 has invalid maxpacket 8 [ 475.108615] usb 3-1: config 1 interface 3 altsetting 0 bulk endpoint 0x87 has invalid maxpacket 8 [ 475.108958] xhci_hcd 0000:04:00.0: WARN: short transfer on control ep [ 475.109328] xhci_hcd 0000:04:00.0: WARN: short transfer on control ep [ 475.109879] xhci_hcd 0000:04:00.0: WARN: short transfer on control ep [ 475.110564] xhci_hcd 0000:04:00.0: ERROR: unexpected command completion code 0x11.
