I recommend you to read the explanation on the website and the install files carefully. If you still have problems, mail it to the lilykde mailinglist or to the developer himself, he will help you for sure!

Drum samples

by Grammostola Rosea

Hi, Me is looking for some nice drumsamples for making a gig file to play midi and stuff. I like to have it a bit jazzy, but rock/blues is fine too. Thanks in advance,

Renoise

by Grammostola Rosea

Hi, There is no good free tracker for linux is it? Are people using renoise here? What does it adds comparing to the apps who are freely available on linux? Can I just use instruments delivered by renoise (how good are they?) and VST or can I also use jack apps like linuxsampler? Regards,

alsa 1.0.17 pros and cons?

by Hartmut Noack

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, the changelog of alsa 1.0.17 says that there are hundreds of new things in this version. I dont have it yet on my boxes and I wonder if it would be wise to upgrade. So if you have it, what is your experience? - - do you see any change for the better(or worse) if jackd runs with the alsabackend? - - do you have hardware, that runs better with the new version? - - if you are a developer: is there any change for the better or worse? best regards HZN -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIwZfW1Aecwva1SWMRAvi8AJ4z/RBxJm24K1SHf/EpvSGqfFz2YgCgh76o Z0w4RHyVM36RGObRrpueIuI= =4/HR -----END PGP SIGNATURE-----

Ubuntu Studio 8.10, -rt and 2.6.27

by Cory K.

Hello all. This is going out to a couple of lists so I can get as wide an opinion as I can. I'll correct any inaccuracies as this discussion progresses. Quick intro: I'm Cory K. Lean on Ubuntu Studio. Hi :) So here's the pickle we're in as I understand it. The way the kernels are now managed in Ubuntu has changed radically in this release. Thus causing our kernel guy *much* more work that ever before. We've had to work very hard to get upstream -rt to support the .26 kernel but, now mainline Ubuntu has moved to 2.6.27. Which upstream -rt doesn't *look* to support yet. So because of these, and other issues that don't matter to the question I have we're looking at these options: * Shipping the -generic kernel with this 8.10 release of Ubuntu Studio and let people compile their own -rt kernel. With a latter PPA release of -rt for testing as upstream support happens. * Ship a out-of-sync 2.6.26-rt kernel, hoping for a Stable Update Release in Intrepid with .27 later. Of some combination of those. Thoughts on what to do? What do users want? (please be mature) -Cory K.

firewire expresscard issue

by gregolak

Hello, I bought an edirol fa-66 which doesn't work on my ACER 7720 laptop (freebob). I tried a few things (disable cpu frequency scaling, change priority with setpci, rtirq script...) without success. I have a Ricoh firewire controller, and I read it can be buggy with firewire audio cards. Therefore I bought an expresscard firewire... and I cannot manage to use it !! I'm aware it isn't really an audio issue, but if someone here know the answer (or maybe you have an idea where else I could have help ?)... It seems recognized as PCI device, but not as firewire. lspci -v gives : 02:00.0 PCI bridge: Texas Instruments XIO2000(A)/XIO2200(A) PCI Express-to-PCI Bridge (rev 03) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=02, secondary=03, subordinate=03, sec-latency=0 Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/4 Enable- Capabilities: [80] Subsystem: Gammagraphx, Inc. Unknown device 0000 Capabilities: [90] Express PCI/PCI-X Bridge IRQ 0 I tried "modprobe pciehp pciehp_force=1", "modprobe pci_hotplug" but same thing... I tried to plug the card before boot (just a few seconds after turning the laptop on, it freezes if I plug it before...) and after. /var/log/syslog while I plus the card : Sep 4 12:04:29 felicien kernel: [ 229.518609] pciehp: Card present on Slot(0002_0000) Sep 4 12:04:29 felicien kernel: [ 229.545152] hub 1-0:1.0: over-current change on port 2 Sep 4 12:04:30 felicien kernel: [ 229.803697] pciehp: No bus number available for hot-added bridge 0000:02:00.0 Sep 4 12:04:30 felicien kernel: [ 229.803765] program_fw_provided_values: Could not get hotplug parameters Sep 4 12:04:30 felicien NetworkManager: <debug> [1220522670.621720] nm_hal_device_added(): New device added (hal udi is '/org/freedesktop/Hal/devices/pci_104c_8231'). If you have an idea... thanks a lot !

Equilization dah?

by schwartz

I have read that using equalization will give each instrument more "space" and make the track clearer and easier to listen to. I sort of understand that this involves removing some frequencies from, say the guitar, so that it does not interfere with vocals, or some such concept. Is there somewhere on the internet I could get some information or better yet, some real life examples, of how to equalize a track? I use Audacity as a sound editor and it does have EQ on it, but I've no idea how to use it. Is there somewhere on the internet that can tell me what frequency ranges the typical bland human voice, harmonica, guitar, bass, and drums each cover individually? That way I'll have a starting point for this adventure into EQ. Or is learning EQ just a case of sloppin' around until something good happens?

realtime kernel on ubuntu 8.04

by Atte André Jensen

Hi My old thinkpad running ubuntu 7.10 died and I'm now on a new laptop (toshiba satellite) with ubuntu 8.04. I'm having alot of trouble getting good realtime performance, not sure what's caused by ubuntu or the laptop. I installed "linux-rt" which seems to have provided some kind of realtime kernel: atte@vestbjerg:~$ uname -r 2.6.24-19-rt I also edited /etc/security/limits.conf to contain: @audio - prio 99 @audio - rtprio 99 @audio - nice -10 I can run jack with rt-priority 80, but am getting x-runs and audio breakup even at light load and conservative latency (17ms). One of the things I have a feeling might be causing trouble is pulseaudio. Should this be disabled, and if so how? What else am I missing? NB: I'm mostly testing this with eXT2, which performed great on my thinkpad. NB2: This is a dualcore, 2Ghz, 2Gb ram machine with a fresh ubuntu 8.04 Any ideas appreciated -- Atte http://atte.dk http://modlys.dk

[ANN] TapStart 0.1 released

by Arnold Krille

Hi all, following a basic rule for open source project "publish early and often" I release the very first (but quite feature-rich) version of TapStart to the public. TapStart is a basic tempo-measurement where you tap some beats and get the (averaged) tempo displayed. But there is more to it: - TapStart also updates the jack-tempo (if a running jack was found during startup) and can even start the jack transport after a defined number of taps. This is implemented for using this thing in jam-sessions to get a click/drum-computer to play in a tempo not known before. - TapStart can also send OSC-messages with the tempo/delay-value as argument to any gives host and path. You can find more information on its page at http://www.arnoldarts.de/drupal/?q=TapStart ofqf (http://www.arnoldarts.de/drupal/?q=node/573) is needed for the osc-part and has to be installed beforehand. The direct-link to the source package is: http://www.arnoldarts.de/drupal/files/downloads/tapstart/tapstart-0.1.tar.gz ofqf: http://www.arnoldarts.de/drupal/files/downloads/ofqf/ofqf-0.1.1.tar.bz2 Have fun, Arnold -- visit http://www.arnoldarts.de/ --- Hi, I am a .signature virus.
