I wish to use a RME BabyFace [1] with Ubuntu. Did someone do it once? Does a driver exist for such RME product? Someone told me that it's possible but so far I couldn't find how. Thank you for your reply, Best regards, Camille Links: ------ [1] http://www.rme-audio.de/en_products_babyface.php

Fwd: sf2 instrument index

by Kaspar Bumke

Forwarding this to LAU, as no one has responded on linuxsampler-devel. See message below. ---------- Forwarded message ---------- From: Kaspar Bumke <kaspar.bumke(a)gmail.com> Date: 8 April 2013 20:44 Subject: sf2 instrument index To: linuxsampler-devel(a)lists.sourceforge.net Hi, I am having some trouble relating the instrument index that LS uses to the one that FluidSynth (FS) displays. For instance, for the FluidR3GM.SF2 that comes with FS, FS reads bank 0, program 0 as being "Yamaha Grand Piano" and bank 0, program 127 being "Gunshot". LS reads FluidR3GM.SF2 as having "Gunshot" as instrument index 0 and 125 being "Yamaha Grand Piano". What logic is LS using to determine these indexes? Regards, Kaspar ---------- Forwarded message ---------- From: Kaspar Bumke <kaspar.bumke(a)gmail.com> Date: 12 April 2013 17:42 Subject: Re: sf2 instrument index To: linuxsampler-devel(a)lists.sourceforge.net Just to make this a bit clearer: LS reads: 0 - "Gunshot" 125 - "Yamaha Grand Piano" FS reads 0,0 - "Yamaha Grand Piano" 0,127 - "Gunshot"

As extensible and awesome as your design may be on paper, the end result is that users get overly fancy, in consistent (and probably slow) GUIs that fiddle with parameters through hidden channels and have poor accessibility. I think that is a real problem.

Questions about LV2

by Julien Claassen

Hello everyone! I've got one or two questions about LV2 plugins in general. I've been experimenting with a couple of sound generating plugins, using mod-host, i.e. not using the plugins' own UIs. Now I noticed, that a couple of plugins did not show all their necessary controls in LV2 ports. Examples are the ZynAddSubFX LV2 plugin http://home.gna.org/zyn/zynadd/1 or the simple sampler by Rui: http://samplv1.sourceforge.net/lv2 In Zyn there were no LV2-control to control the engine. the sampler offered a fair deal of controls, but didn't allow me to sample or load a sample. I could connect an instrument to the input ports and apply the effects (chorus, flanger, phaser and delay) to it. So: is there - in theory - an LV2-port type, that allows sending strings - i.e. filenames. Is there another standardised way for plugins and their UIs to communicate? If not, are there thoughts about such things in the LV2 developing community for just such cases, where one can't or doesn't want to use the original UIs of a plugin? Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

SooperLooper 1.7.0 released

by Kaspar Bumke

Grab the new version on the site: http://essej.net/sooperlooper/download.html CHANGES FOR 1.7.0 GUI: - Fixed SooperLooper being mistakenly identified as remote - Now ignoring non audio and non .slsess files in load and save file selection dialogues - Mute now flashes when waiting to go into mute instead of rev flashing - Mute of others flashes instead of solo flashing when going in and out of solo - Fixed CC bindings for commands that need to be registered as hits - MIDI bindings choice now sorted alphabetically - File selector now defaults to home and tracks last load/save - Removed arbitrary maximum loop memory limit in Add Custom Loop... - Fixed issue of some controls not showing up when you have more than 5 loops SooperLooper engine: - Fixed issue of not being able to load audio files from session when not started from the same directory - Fixed fade not working after undo_all - Removed 1 sample click in multiply - Fixed individual loop monitor not being sent to main-out - Fixed toggle MIDI bindings requiring double press when first loaded - Fixed some clicks when undoing - Added CCon and CCoff message types to midi bindings - Can now mute and un-mute when loop is in Off state - Fixed bug where long-presses were causing undo-all when they weren't supposed to OSC: - OSC Auto Update time can now be set between 10-100ms - "osc.udp://" can be omitted from the return URL parameter of any OSC message - SooperLooper no longer seg-faults when an invalid return URL is given AU: - State and waiting AU parameters now working - Fixed parameter update race condition, so values reflect newly changed state - There are now up to 8 stereo sidechain outputs available (individual outputs for each loop), but for some reason still only 4 stereo inputs available (at least as shown within Live)... it isn't clear why there are fewer input buses, it might be a Live limitation. Others: - Small maintenance on help output, OSC doc file and indentation, spelling etc. - HTML docs on website now include full MIDI command reference

HYDROGEN DRUM MACHINE ACCESSIBILITY FOR BLIND MUSICIANS?

by Rusty Perez

Hi folks, does any one know if the hydrogen drum machine is accessible for blind users? I know it has a gui, but I don't know what it's written in. And I don't know if there are any alternatives for running it. Thanks! Rusty

Fwd: Matching Pursuit Toolkit (MPTK) 0.7 released

by Dan S

Dear all, Matching Pursuit Toolkit (MPTK) is a fast and efficient library (with Matlab and Python wrappers, and commandline tools) for the sparse decomposition of multichannel audio signals. Version 0.7 is now officially released: https://gforge.inria.fr/frs/?group_id=36 Changes in 0.7: * New pyMPTK wrapper, enables direct use of MPTK within Python * Enabled GPD with the Dirac, Constant and Nyquist blocks * Anywave block now working from command-line mpd and mpr * Improved XML parsing of books (note: the API to use for writing new plugins changes as a result of this; and MPTK books are now written with an outer <mptkbook> tag surrounding book and dict) * Slight Matlab API change: second “dict” arg now needed for reconstruct(book, dict) Best Dan -- http://www.mcld.co.uk

New Swedish hiphop album made completely in Linux!

by Gabbe Nord

Since quite a while back, I've been a part of a Swedish hiphop group called "Raptimus Prime" together with two of my good friends, and we've just released our first album! Even though few people on here probably know Swedish, maybe someone finds it amusing anyway! :) The album consists of 13 tracks, and was made 100% in Linux from start to finish. I'm extremely happy and proud that we could make all of this _almost_ exclusively using free and open source software! We've recorded/mixed/"mastered" it all by ourselves, mainly using the following software/plugins: Ardour2 Ardour3 Some Hydrogen Calf plugins Salamander Piano TAL NoiseMaker linuxDSP plugins Sonatina Symphonic Orchestra zita-dpl1 ..and a lot of other stuff I've probably forgot to mention! ;) You can find it at a number of different sources: Bandcamp: http://raptimusprime.bandcamp.com/ Soundcloud: http://www.soundcloud.com/raptimusprime PirateBay in various formats: FLAC: http://thepiratebay.sx/torrent/8451980 OGG: http://thepiratebay.sx/torrent/8451976 MP3: http://thepiratebay.sx/torrent/8451978 It's also available at Spotify if anyone uses that. ..and since I'm not sure if torrents/the other links provided work for everyone, here's a direct link for the OGG-version that *should* work. Please let me know if it doesn't so I can fix it: https://dl.dropboxusercontent.com/u/19258546/RaptimusPrime-Styrketarar%5B20… Lastly, thank you so much all developers/users of open source/linux audio in general, for making this all possible! I'm very happy to be a part of this community, with many more musical projects to come! Cheers! Kind regards, Gabriel/zth
