[LAU] M-Audio MIDISport UNO Compatable with Linux?

mowestusa — 2008-08-30T03:41:13

Hello, I'm trying to set up a simple Midi interface between a Linux box and a Midi keyboard. Will the M-Audio MIDIsport UNO work with Linux? I bought it on sale for $19.99, and I'm hoping it will work with Rosegarden and other Midi programs under Linux. Thanks, ---------------------------- | Steve | | mowestusa-/E1597aS9LQAvxtiuMwx3w< at >public.gmane.org | | mowestusa.nixsyspaus.org | ----------------------------

[LAU] Compiling vamp-sdk and Rubber Band on Ubuntu Studio 64

Darren Landrum — 2008-08-29T22:48:42

Maybe someone can help me out with this? vamp-sdk appears to have no install targets, so I move everything manually to their places, but the configure script for Rubber Band still misses it. I'm running into all sorts of errors I've never seen before. Within the vamp source directory, I can do: make sdk and get that to work okay. Then what? The README also says I need to alter the Makefile to "suit my system", but when I try to change to directory paths at the beginning to places like /usr/include/vamp and /usr/local/lib/vamp-sdk, I just get an error saying those build targets don't exist. I did use sudo. Apparently, vamp needs to show up in something called PKG_CONFIG_PATH, which right now on my system has absolutely nothing in it. I've read the pkg-config man page, and am no closer to solving this issue. Thanks for the help.

[LAU] connect seq24 to linuxsampler

Hi, How do I play a midi file with seq24 and LS? I don't understand how those connections work.

[LAU] A Linux Audio distro that can keep up?

Darren Landrum — 2008-08-29T20:58:23

Is it really too much to ask for a distro which is supposedly dedicated to audio and video production work to keep up with the latest versions of those types of programs and libraries? Ubuntu Studio 64 v8.04 (Hardy) is still stuck at Ardour 2.3. I can't even get the Rubber Band library to compile because I can't get vamp-sdk to compile either, so now I can't compile Rui's Qtractor with the options I want. You'd think they'd all be in the Ubuntu Studio repositories, but they're nowhere to be found. Is there a distro for audio out there with a nice real-time kernel that can keep up with the updates so I don't have to keep doing it all manually? Thanks!

[LAU] [ANN] Qtractor 0.2.1 (fainty diva) released!

Rui Nuno Capela — 2008-08-29T20:14:26

Howdy! Vacation time is now gone and the rentrée is upon us, at least on this hemisphere side of the globe ;) Silly season, beloved August, summertime it is. And before it's too late, I'm proud to announce that a new alpha has summoned to the challenge: Qtractor 0.2.1 (fainty diva) has been released! Release highlights: - Gradient eye-candy (NEW) - DSSI multi-instance plug-in issue fixed - Clip waveform/piano-roll rendered while recording (NEW) - MIDI pitch-bend, omni-channel filtering and recording fixes - Play-head positioning in the thumb-view (NEW) - And many few more (see change-log below:) For the clueless: Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework [1]. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio [2] and the Advanced Linux Sound Architecture (ALSA) for MIDI [3] are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Author: Rui Nuno Capela Weblog: http://wwww.rncbc.org Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) [15] version 2 or later. Features: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework [1] (no Qt3 nor KDE dependencies). - Uses JACK [2] for audio and ALSA [3] sequencer for MIDI as multimedia infrastructures. - Traditional multi-track tape recorder control paradigm. - Audio file formats support: OGG (via libvorbis [6]), MP3 (via libmad [7], playback only), WAV, FLAC, AIFF and many, many more (via linsndfile [4]). - Standard MIDI files support (format 0 and 1). - Non-destructive, non-linear editing. - Unlimited number of tracks per session/project. - Unlimited number of overlapping clips per track. - XML encoded session/project description files (SDI). - Point-and-click, multi-select, drag-and-drop interaction (drag, move, drop, cut, copy, paste, delete, split) - Unlimited undo/redo. - Built-in mixer and monitor controls. - Built-in connection patchbay control and persistence (a-la QjackCtl [13]). - LADSPA [5], DSSI [11] and native VSTi [12] plug-ins support. - Unlimited number of plug-ins per track or bus. - Plug-in presets, programs and chunk/configurations support. - Audio/MIDI clip fade-in/out (linear, quadratic, cubic). - Audio clip time-stretching (WSOLA-like or via librubberband [9]), pitch-shifting (via librubberband [9]) and seemless sample-rate conversion (via libsamplerate [8]). - Audio/MIDI track export (mix-down, merge). - Audio/MIDI metronome bar/beat clicks. - MIDI clip editor (piano roll). - MIDI instrument definitions (a-la Cakewalk(tm) [15]) - JACK transport sync master. - MMC control surface enabled. - Configurable keyboard shortcuts. Requirements: - mandatory libqt4 [1] libjack [2] libasound [3] libsndfile [4] LADSPA [5] - optional libvorbis [6] libmad [7] libsamplerate [8] librubberband [9] liblo [10] DSSI [11] VST-SDK [12] Download: http://downloads.sourceforge.net/qtractor/qtractor-0.2.1.tar.gz Change-log: 0.2.1 2008-08-30 The Faint Diva - Gradient eye-candy now featured for clips, tracks and mixer strips widget backgrounds, disabled on configure time (--disable-gradient). - MIDI pitch-bend/wheel events are now captured/recorded properly; in fact, there was this ancient bug, now squashed, as all MIDI clips weren't being stored at all if there weren't a single note event captured. - MIDI channel translation is finally in effect on monitored tracks, specially the ones set in omni-channel input mode. - MIDI open files dialog gets a few more file filter types now. - Playhead position is now shown, updated and can be also set on the main toolbar session thumb-view (shift-click to set the playhead). - The floating selection, as shown for a clipboard pasting operation, has been corrected regarding time scale (horizontal zoom) changes, while in the main track-view. Also fixed final position snapping precision (spotted in bug #2055846). - Current tempo and snap-per-beat setting now survive session cycling. - DSSI plugins implementing run_multiple_synths (eg. fluidsynth-dssi) are now formally supported according to the DSSI spec (hopefully); note that previously one could only have one DSSI plugin instance loaded in session in any given time, otherwise a sudden crash was in sure demand when either plugin got activated (fixes bug #2048198). - Audio plugin outputs now overrides each other when the number of output ports does not match the number of mix-down audio channels and thus fixing a nasty crash bug in the process. - All custom font sizes are now set relative to default global font. - Changing loop points by dragging on the time rulers is now mapped as undoable/redoable commands as it ought to be ever since. - Drop-span option (View/Options.../Drop multiple audio files into the same track) now takes into effect the current session snap-per-beat setting when concatenating multiple audio clips. - All plugins get their default bank/program selected on insertion. - Make record armed tracks muted for playback, a needed regression to let both audio and MIDI tracks behave consistently regarding input monitor switching through output. - Fixed a pretty old and shameless bug regarding MIDI clip recording, in which cases the queue start time offset was not taken into account, with captured events being recorded with erratic long delays. - Almost complete refactoring of the clumsy audio peak file classes, possibly making it even clumsier but straight neverthless, with the noble and final aim to build it in-flight and draw the waveforms while recording is rolling. - Recording clips get their initial name labels drawn while fade-in/out handles are dropped as found pretty useless while recording. - Escape key now closes connections and mixer widgets as found usual. Disclaimer: Qtractor is (still) in some alpha stage of development, although already functional it surely has a plenty of lurking bugs. It also lacks some features that some might find critical in the application field. All is (still) not lost, as the following are among the ones planned to be worked on in the times to come (not in any particular order): - Automation and MIDI controller mapping. - Session/project templates. - Puch-in/out and loop recording (takes). - Audio clip cross-fading. - Audio effect send/return aux. inserts. - Clip locking, muting, normalize (gain). - LV2 plug-in support. - JACK MIDI support. - Tempo and key signature map. - Paste-repeat command. - MIDI SysEx manager. - MIDI event list editor. - MIDI editor (piano roll) draw mode. - MIDI groove/swing quantize. - OSC interface. - Scripting. - Etc. etc. References: [1] Qt4 (core, gui, xml), C++ class library and tools for crossplatform development and internationalization http://www.trolltech.org/products/qt/ [2] JACK Audio Connection Kit http://jackaudio.org/ [3] ALSA, Advanced Linux Sound Architecture http://www.alsa-project.org/ [4] libsndfile, C library for reading and writing files containing sampled sound http://www.mega-nerd.com/libsndfile/ [5] LADSPA, Linux Audio Developer's Simple Plugin API http://www.ladspa.org/ [6] libvorbis (enc, file), Ogg Vorbis audio compression http://xiph.org/vorbis/ [7] libmad, High-quality MPEG audio decoder http://www.underbit.com/products/mad/ [8] libsamplerate, The secret rabbit code, C library for audio sample rate conversion http://www.mega-nerd.com/SRC/ [9] librubberband, Rubber Band Audio Time Stretcher, an audio time-stretching and pitch-shifting library http://breakfastquay.com/rubberband/ [10] liblo, Lightweight OSC implementation (needed for DSSI GUI support) http://liblo.sourceforge.net/ [11] DSSI, an API for soft synth plugins with custom user interfaces http://dssi.sourceforge.net/ [12] VST SDK, Steinberg's Virtual Studio Technology (see README.VST) http://www.steinberg.net/ [13] QjackCtl - JACK Qt GUI Interface http://qjackctl.sourceforge.net [14] GNU General Public License http://www.gnu.org/copyleft/gpl.html [15] Cakewalk (by Roland), powerful and easy-to-use tools for Windows-based music and sound production http://www.cakewalk.com/ Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc at rncbc dot org http://www.rncbc.org

[LAU] Lexicon Omega

Joshua Boyd — 2008-08-29T19:27:18

My Omega seems to have developed flacky output jacks, and maybe also flacky input jacks. Has anyone seen this on theirs, since I seem to recall a few people on here using them? I'm torn between sending it to be repaired, trying to repair it myself, versus just replacing it with a simpler device and dragging my mixing board back out. I'm concerned that trying to send it out for repair would end up costing more than I paid for it or even almost as much as a brand new one would be. Has anyone who owns one tried opening it up?

[LAU] Standard Sample Dump with amidi

Mirko Horstmann — 2008-08-29T12:04:37

Hi there, I'm currently trying to send samples to a semi-ancient synthesizer (a Yamaha SY99), which has a sample RAM of 512kB built in. The way I do it, the synth seems to receive "something" but doesn't really acknowledge that it has received the whole sample and is acting strange afterwards (won't make a sound until I turn off and on the machine and then there seems to be only garbage in the memory). I understand that the intersection between the sets of SY99 users and Linux users is probably quite small and that I may have to ask on the SY99 list at Yahoo what the synth's behaviour means. But I couldn't find any definite answers as to whether what I do on the Linux side is any good: I save the sample as mono, 16bit, 48000kHz (which the synth is supposed to be able to handle) and in ".sds" format (using Sweep, which uses libsndfile). The beginning few bytes of that file seem to be compliant with a midi sysex dump. Then I use the following command to send it to the synth ("hw:0,0" being the midi port of my M-Audio Audiophile): amidi -p hw:0,0 -s sample.sds Is this supposed to work at all or am I missing something? Thanks, Mirko

[LAU] Notation: The State of the Mess

David Baron — 2008-08-29T09:14:36

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.

[LAU] Intercept (alsa) audio from totem-xinelib

Johannes — 2008-08-28T15:30:21

Hi all, I would like to watch a video DVD with totem and send the audio to a file instead of the sound system (that is, capture the DVD audio as it flows). Could someone point me to the right direction? I tried adding a .asoundrc file to my homedir, containing pcm.fileout { type file slave.pcm "hw:0,0" file alsaout.raw } but can't figure out how to actually activate "fileout". My installation is ubuntustudio (gutsy, i686) with totem-xinelib. I picked ALSA for "Music and Movies > SOund playback" in System > Preferences > Audio (=gnome-sound-properties) The soundcard selected in QAMix is "VIA8237 (hw:0)" Thanks all in advance, Johannes

[LAU] interrupt settings

D. Sen — 2008-08-25T22:35:46

Currently my RME Madiface and nvidia share the same interrupt. They are on the PCIe bus. I have tried switching physical slots without any success. According the motherboard manufacturer (Intel), the interrupt routing is controlled by the OS and not by the BIOS. What options are available to do this? Thanks, Dee

Aurelien — 2008-08-25T16:48:12

Hello all, So here it is, our studio is finally set up, and we currently are recording two albums (Sebkah-Chott's Nigla[h] and Sebkha-Chott's De la Persistance, released on the 30th of October by Muséa Records) on it. Here is the stuff we have, and how the whole thing is plugged and so on. We'll try to describe all of that on a webpage as soon as possible. PC / Hardware: - Proc: Intel Q6600 Core 2 Quad - Motherboard: Gigabyte P35C-DS3R - GPU: ATI Radeon X1050 - RAM: 8Gb DDR800 - dual channel - 1 sys HDD 80 Gb WD Caviar with 8Mb cache - 2 data HDD 250 Gb WD Caviar with 16Mb cache striped on a RAID - RME HDSP9652 HDDs management: - swap is dispatched on the three HDDs with the same priority, so that it does swap as if there was a RAID 0 array. - the two partitions remaining on both 250Gb HDD are striped in a RAID 0 array. OS: - Debian AMD64 Lenny mixed with some 64studio packages - realtime kernel (compiled by ourselves) - Ubuntu Studio 64 Softwares used: - Ardour 2.4.1 (will change with updates) (for recording and mixing the whole thing) - Rosegarden 1.7 (for playing "witness" instruments and editing notations) - Qsynth - Muse (when Rosegarden has some dependancies conflicts with Ardour) - hdspmixer and hdspconf External hardware: - Alesis HD24XR (which is plugged through 6 ADAT -max- to the HDSP9652, the worldclock is the one from the RME, it finally consists in a 24-tracks direct-to-disk recorder) (- Yamaha DM2000 (id.)) / not always present Preamps: - 6x TL-Audio 5001 (4x tube preamps) - 1x TL-Audio 5051 (1x tube preamp) Mics: - 1x Neumann TLM 103 (voice and instruments like violin, soprano saxophones, and so on) - 1x Neumann KM 184 Stereo Set (over heads, very sharp in treble, nice to hear, used with drums, percussion, acoustic guitars, ...) - 1x AKG C414 XLS Stereo Set (id. KM184, but a bit different) - 1x EV RE20 (for low frequencies, like Barytone Saxophone, and so on) - 1x Sennheiser MD421 U (for almost everything!) - 1x Shure Beta 91 (for Kick) - 1x Shure Beta 52 (for Kick) - 2x Shure Beta 56 (for snares and so on) - 6x Beyerdynamic Opus 88 (for snares and toms) Other: - Line 6 Pod XT Pro (bass and guitar), which are plugged through AES/EBU and S/PDIF inputs, avoiding a conversion. So here it is. The only purposes of this studio is to produce FREE ARTS and to make some LESSONS about how to use free softwares in professionnal audio context. Don't hesitate to ask me what you wonder! See you.

[LAU] Playing lilypond midi drum files with synth/sampler

Grammostola Rosea — 2008-08-24T17:26:52

Hi, I want to write drum score in lilypond, export it to midi and play that with a sequencer. Which programs are the best for this? Muse, Rosegarden, Qtractor? Linuxsampler (gigedit) or specimen? How does the mapping work? The sequencers do use standard midi percussion maps...(?) Here is one: http://www.midistudio.com/Help/GMSpecs_PercMap.htm Key 35 is that key 35 on a 88 keys piano from left to right? so key 35 is G3? Thanks in advance,

[LAU] native linux vsts (esp glitch)

Atte André Jensen — 2008-08-24T11:03:40

Hi I recently bought energyXT2 (commercial, native linux daw) and now I'm looking for vst plugins. It seems that the program could be run through wine (supporting windows vsts in dll-format), but somehow I have the feeling that running the native version is faster and should be more stable. So my questions are: 1) What would must-haves native-linux vsts (I have freeverb, the mda's and the loser-plugins + a few more)? 2) I contacted the author of glitch (http://illformed.org/blog/glitch/), which seems like a really cool tool, asking if was interested in providing a linux version of glitch. Can anything in general be said regarding how hard it would be to supply a linux version? I guess it's not only a matter of under compiling, right? I'm willing to help as much as I can, but my programming is no that great, are others interesting in helping, for instance by porting glitch, should the developer be willing to play along. 3) I know there are some non-free issues with vsts, but what exactly are those, and provided I'm right in assuming that the linux audio (dev) community has a negative attitude vsts, what would the main arguments against it be? 4) Anyone here using vsts (both native and windows)? If so how do you use them, in which hosts, and with which benefits/problems? Who do you use them over dssi or ladspa alternatives? Looking forward to hearing from you!

[LAU] MIDI latency in Ubuntu 8.04

David Baird — 2008-08-23T05:03:45

When I use the kernels from Ubuntu 8.04, my MIDI latency becomes horrible. I have an external keyboard that connects to the computer and then proceeds to loop-back out to external synthesizers. By horrible, I mean that there is quite clearly a delay from when I hit a key on my keyboard to when sound comes out the synthesizer. If someone knows a tool I could use to measure the latency, I'd be glad too. Otherwise, I'd just guess it is somewhere around 100 milliseconds. When I switch back to my prior kernel from Ubuntu 7.10, the latency becomes great (but the X server and other things stop working, thanks to the magic of Ubuntu). Here are the kernels I've tried out with Ubuntu 8.10: 2.6.24-18-generic Bad latency 2.6.24-18-rt Bad latency 2.6.22-14-generic (This is the kernel from Ubuntu 7.10) Excellent latency Has anyone else had this problem? Do you know if it is kernel-related, library-related, or Ubuntu-related? It almost seems kernel-related, but why? -David

[LAU] windows (wine) apps can no longer see alsa midi ports

Robert Persson — 2008-08-22T17:47:29

While I was asleep last night wine applications lost the ability to recognise alsa midi ports (external controller, midi-through etc). In other words I was able to work with midi last night, but something has changed. In both Reaper and in Tracktion 3 Demo the box in the preferences where all the devices were listed last night is now empty. I thought it might have been a wine upgrade from the official ubuntu hardy version to the one in the winehq repository (1.1.2), but rolling it back made no difference. However at some point while I was trying to get wineasio-x working I tried changing winecfg to disable alsa. When I first noticed that midi wasn't working winealsa was still disabled, but after I re-enabled it it still refused to work. In other words I had done something that could reasonably be expected to cause wine midi to stop working, but it didn't start working again once I had put this right. Does anyone have any idea what is going on here? Many thanks :) Robert

[LAU] Using all four tracks on the M-Audio Fast Track Pro?

Don Marti — 2008-08-22T16:58:21

I have an M-Audio Fast Track Pro, and it works great for recording in stereo with Audacity. (my setup: http://www.linuxworld.com/community/?q=node/1740 ) Now I need a couple more channels. I've done web searches for every mention I can find of this box with Linux, and I don't see any examples of anyone recording more than just stereo. Anyone able to see four tracks?
