Sure. we went through great pains to make sure they worked. Watch out for DKMS. (http://linux.dell.com/projects.shtml) It should help the use of proprietary (or otherwise) drivers and kernels. I have to look into it a bit still. -Cory K.

native linux vst, esp zynaddsubfx

by Atte André Jensen

Hi Yesterday I stumbled upon http://www.anticore.org/jucetice/?page_id=8. I was surprised to find zynaddsubfx there, but unfortunately it doesn't work. The problem is that the plugin doesn't get it's UI drawn, instead there appears a window about the right size but it gets filled with some of the hosts UI. There are at least one other plugin from that page that behaves like this. What could be the cause for this? I can think of several possibilities: 1) Problems with the host's (energyXT2) graphical rendering. 2) In compatibility between the plugin and some graphical lib on my machine. I tried to compile the plugin but it failed. I then downloaded the vst_sdk(version 2.3, 2.4 and 3) from steinberg and made the compilation run a bit further by copying the missing files. Now it stops at: make[2]: Entering directory `/home/atte/eXT2/plugins/instruments/new/zynaddsubfx/src/Output' make[2]: *** No rule to make target `../../vstsdk2/source/common/AEffEditor.hpp', needed by `VSTaudiooutput.o'. Stop. make[2]: Leaving directory `/home/atte/eXT2/plugins/instruments/new/zynaddsubfx/src/Output' make[1]: *** [Output] Error 2 make[1]: Leaving directory `/home/atte/eXT2/plugins/instruments/new/zynaddsubfx/src' make: *** [all] Error 2 The file AEffEditor.hpp is nowhere to be found inside the sdk's I downloaded, I suspect it's because it's from an older version, in any case how do I proceed with compiling zynaddsubfx as a vst plugin? 3) Problems related to compiz/accel/X on my machine. I've seen this before: some program doesn't like to be run under compiz and have flakey redrawing. How can I run a non accelerated xorg (to see if this fixes the problem)?

No audio going between JACK and sound card

by ANDERSON GREGORY

I just installed Fedora 9 but I am having trouble getting JACK configured properly. The only way I can get jack to start without failing is by using the 'dummy' driver. But I cannot get sound out of the computer (even though ardour is working properly and playing) or any sound into the computer. Is this 'dummy' driver an actual driver? I had it woring excellent in Fedora 8 but in my absent mindedness did not write down how it was configured. I do believe I was using alsa though. Do I need to set the path to the driver, it just says 'jackd' now? If someone could answer my questions or at least point me to a resource I would be very thankful. Greg.

kicks

by Dave Phillips

Greetings, Recently I decided to learn some well-known rock guitar solos note-for-note, with the assistance of some Linux sound and music software. Naturally I used Audacity to learn the solos exactly (Change Tempo is just toot sweet), but I wanted to work on the sound of the solos as well their notes. I found some nicely arranged MIDI files for some of the tunes, I used Rakarrack for the effects, and I used AlsaPlayer to play the audio files (where I couldn't find MIDI arrangements). Great instructive fun. I've worked out the solos to Cream's Badge and to Dire Straits' Sultans Of Swing, now I'm on to Joe Perry's leads in Aerosmith's Walk This Way. Yeh, pretty old school, but still great solos. It's excellent exercise too, keeps me from getting bored. Sometimes Bach just doesn't rock enough... :) I've also been sequencing a pseudo techno demo, again using only Linux audio softsynths, including AMS, QSynth, LinuxSampler (with sounds from the PSIndustrializer synth), and the new Discovery VSTi (in JOST), with help from the midirgui MIDI channel router and the mighty JACK. I'll post the results when it's done. Anyway, not to get all weepy here, but I wanted to take a moment to give some thanks to the developers who make it all possible. So, thanks, devs, your generosity is deeply appreciated. Back to the rack... Best, dp

[ANN] Virtual MIDI Piano Keyboard 0.1.1

by Pedro Lopez-Cabanillas

This is a maintenance release, trying to solve the performance problems reported by some people for the first public release announced last week. Thank you very much for your comments! Virtual MIDI Piano Keyboard is a MIDI event generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. Changelog: 2008-09-05 0.1.1 * Bugfix: crash at startup when no MIDI input devices were available. * Changed default key bindings map: the new default one is equal to Impulse Tracker and other programs. More keys are mapped now. * Several optimizations in keyboard handling code and display updates. 2008-08-31 0.1.0 * First public release Copyright (C) 2008, Pedro Lopez-Cabanillas License: GPL v3 Web site: http://vmpk.sourceforge.net http://sourceforge.net/projects/vmpk Sources: http://downloads.sourceforge.net/vmpk/vmpk-0.1.1.tar.bz2 http://downloads.sourceforge.net/vmpk/vmpk-0.1.1.tar.gz Windows setup package: http://downloads.sourceforge.net/vmpk/vmpk-0.1.1-setup.exe openSUSE RPM packages: http://software.opensuse.org/search?baseproject=ALL&p=1&q=vmpk Regards, Pedro

Notation: The State of the Mess

by David Baron

Very little has progressed since the last thread here. Really. New features and fixes have gone into nted and denemo but do a song on them? Here's the score, he he: mscore -- promises to be the opensource Sibelius. Great program, somewhat funny but very usable UI. I have not succeeded in doing a song start to finish on this goody. Will hang up the system at some point and big-red-switch time. I can import musicXML and edit from there. The program will not save chord symbols on scores imported from musicXML (which apparently does not support them, but mscore certain works fine with chord symbols otherwise!). Denemo --The lilipond front-end finally has a useful feature set. Many of the newer programs force upon the user too much "theory." Partial measures, i.e. starting on the upbeat, are a common enough device in music. Mscore makes one select the lead measure and set its length property. Notedit, sinply place the bar! Denemo? A future incarnation, I suppose. Denemo will not import lilipond files from noteedit. Nted -- one successor to noteedit. Has similar limitations as denemo. Canorus -- one successor to notdedit. Heard of this lately? Last version was nowheres near ready to play. Rosegarden -- has been around a while. I could not get into scoring with it. Same idea of too much imposed "theory." Unfortunately, is segfaults out right now so can do no more with it. Noteedit -- old, no longer developed or supported -- but with its hoky-poky interface, still easier for select and click note entry than any of the others and gets the job done, period. Noteedit Auto-adds measures as needed but lets one edit as one pleases including partial measures. (I guess the paradigm in ALL the other programs of presenting rest-filled-out measures all the time is what I do not like about them.) If lead-sheet chord symbol entry were more convenient, I might look nowhere else. Exports to lilypond (not 100% correctly but usually prints OK), musicXML, abc, musixTEX and MIDI which will get you into most other programs. I wish the successors would import its files directly--if they claim to be successors, this would make some sense! OT-aside: What does rosegarden (and noteedit) need with KDE? QT would certainly be sufficient, and not dealing with KDE's excess baggage might solve a lot of the crashing problems. I run KDE3 and KDE4 all the time, love 'em, but requiring its libraries for these programs makes little sense.

Sneakernet advice

by Chip VanDan

I'm in a bit of a pickle lately and I was hoping for some advice. I'm currently in a situation where I have access to a computer but not from my laptop that I want Linux on. I'm used to using Fedora Core 3 with Planet CCRMA, however that is completely impossible without having an Internet connection seeing as how everything is managed using yum or apt. I've tried Dynebolic on my laptop and it completely sucked, the sound card didn't work properly. I just tried Ubuntu 8.04 and it worked beautifully, then I found Ubuntu Studio which is based on 8.04, however it's only available in DVD format and I don't have a DVD burner on the computer that has access. Before I get the answer I'm expecting I'll say that I cannot put the laptop on the same network as the computer that has access, that is not allowed where I'm at. Is there a way to download the ISO file and run it from a USB Flash drive? Or any other suggestions, such as better CD based distributions? -- -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCA/FA/S/O d+(--) s+: a-- C+++ L++ P E-- W++ N- o K? w O-- M- V- PS+ PE- Y+ PGP t- 5-- X R- !tv b++ DI++ D+ G+ e+/++ h--- r--/+++ z+++(*) ------END GEEK CODE BLOCK------
