I am pleased to announce the release of Composite 0.006.2. This is a bug-fix release. ABOUT ----- Composite is (or, will be) a software application/system for real-time, in-performance sequencing, sampling, and looping. Currently the main feature is the LV2 Sampler that supports Hydrogen drumkits. CHANGES ------- * LV2 Sampler: Fix logic error with uri-map by passing the Event URI as the `map` parameter. This also works around crashes in slv2 and zynjacku (which is a bug on their part). STATUS ------ Composite is a project with a large vision. Here is the status of the different components: composite-gui: Alpha (i.e. "a broken version of Hydrogen") composite_sampler (LV2): production/stable, no GUI libTritium: Not a public API, yet. LINKS ----- Composite: http://gabe.is-a-geek.org/composite/ Plugin Docs: file:///home/gabriel/code/composite-planning/plugins/sampler/1 Tarball: http://gabe.is-a-geek.org/composite/releases/composite-0.006.2.tar.bz2 Git: http://gitorious.org/composite git://gitorious.org/composite/composite.git HOW TO USE THE PLUGIN --------------------- To use the plugin, you need the following: * A program (host) that loads LV2 plugins. * A MIDI controller. * An audio output device. :-) The following LV2 hosts are known to work with this plugin: Ingen http://drobilla.net/blog/software/ingen/ ardour3 (alpha) http://ardour.org/ lv2_jack_host http://drobilla.net/software/slv2/ zynjacku http://home.gna.org/zynjacku/ If you don't have a hardware MIDI controller, I suggest using jack-keyboard (http://jack-keyboard.sourceforge.net/). The first time you run the sampler, it will create a file ~/.composite/data/presets/default.xml, which will set up presets on Bank 0 for the two default drum kits (GMkit and TR808EmulationKit). Sending MIDI PC 0 and PC 1 will switch between the two kits. See composite_sampler(1) for more information on setting up presets. ACKNOWLEDGMENTS --------------- With this release, I would especially like to thank: Alessio Treglia - For quickly packaging 0.006.1 and getting it into Debian sid. Benoit Delcour - For quickly testing and reporting this issue with the LV2 Sampler. Peace, Gabriel M. Beddingfield

Decompressing Propellerhead Reason Refills

by Marcel Bonnet

Hi. Does anybody knows if there is a way to decompress the Propellerhead Reason Refills? I would like to extract some of its audio samples (drums and mellotron) and use them with FluidSynth, per example. -- Marcel Bonnet

Recording of a 'natural' talent.

by Folderol

Warning! This file is about 12M and the audio runs for 8 1/2 minutes. I recorded this in 1982, by hanging out of an attic window at about 4:30am. This was as close as I could get to 'Blackie' who always sat high up in the same chestnut tree. The time was dictated by the need to get zero traffic noise. Even then I was at this every morning for about a week! The MIC was a bog-standard Unidyne B plugged straight into a Casio DA-7 portable DAT machine (cost an arm and a leg in those days). I was getting a bit paranoid about losing this so took a Wave copy from the machine in the late 1990s. Blackie is actually a copyright infringer. He copied the most notable part of his song from a friend who used to whistle that handful of notes frequently - to everyone's annoyance. However, we forgave Blackie as he'd been hearing it virtually from hatching. You see, he'd fallen out of the nest and Terry (same one as I've mentioned previously) hand reared him. Also, I swear that at a couple of points he's actually laughing! A final twist was that a couple of years later we saw and heard several young blackbirds with a remarkably similar song. http://www.archive.org/download/BitsAndPieces/Blackbird.mp3 -- 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.

Re: [LAU] question about normalize-audio

----- Original Message ----- From: Paul Davis Sent: 07/22/11 07:18 AM To: shane richards Subject: Re: [LAU] question about normalize-audio >> * normalize the RMS volume of a group of samples > in general, "normalization" tends to refer to operations on the actual > sample values, not an average computed number like RMS. >> * max value of the loudest peak in the group doesn't exceed xxx db > if it doesn't do that, its not really normalization. >> * no limiting/clipping/compression > normalization would never involved any of these 3 operations. if it > did, it would be called limiting or clipping or compression. I'm commenting specifically on the "normalize-audio" program (I'm not aware of anything else), which computes either by peak or RMS, but when computing by RMS the fact that a peak may go over 0db is compensated for by limiting/clipping, instead of changing the gain value for all samples to keep everything under a given limit. It seems you can have one or the other, but not both. In short, I want the "perceived loudness" values levelled without losing any peaks, and without denormals being introduced. > are you asking about how to do this as a user (i.e. "what tools are > available to let me do this?") or as a programmer/developer/tinkerer > (i.e "how would you go about doing this?") As a user. 500+ drum samples to be converted into Hydrogen kits. So something scriptable if you know of any.

[ANN] TYOQA: Qtractor 0.5.0 - The Alpha Zulu awakening!

by Rui Nuno Capela

Howdy! TYOQA (the year of qtractor automation for the clueless) is now pretty real. I'd say it's all been my my prerogative, again and again, doing things my own way (do I hear Frank S. singing? nope. move along...). Is this the time to do the unthinkable? Should I tag it as beta now? Should I? There's one single reason for not doing so and a couple of others to make it through: 1. basically it's all the same functionality that stays put or improved in a few spots; 2. it just feels like it! :) Now comes the mighty corrosive one: I'll be off on vacation soon. Summer is waiting for me. And I just hate to miss that kind of deadline. Woohoo! Is there anything else to mention? Go ahead, make your day: Qtractor 0.5.0 (alpha zulu) is now released! Release highlights: * TYOQA! Audio/MIDI track and plugin parameter automation (NEW) * MIDI controller catch-up behavior (NEW) * All zooming in/out relative to views center (NEW) * Audio gain/panning smoothing changes (FIX) Happy summer 2 y'all! Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.0.tar.gz - source package (openSUSE 11.4): http://downloads.sourceforge.net/qtractor/qtractor-0.5.0-3.rncbc.suse114.sr… - binary packages (openSUSE 11.4): http://downloads.sourceforge.net/qtractor/qtractor-0.5.0-3.rncbc.suse114.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.5.0-3.rncbc.suse114.x8… - from the dusty shelf: user manual (anyone?): http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - MIDI controller learn/catch-up sees the way in: MIDI controller changes are now only effective after catching-up with their respective program parameters, avoiding abrupt jumps and keeping a safe and continuous behavior. - Track/Height menu is now featured, giving access to Increase, Decrease or Reset the current track height. - All changes to audio gain and panning on tracks and buses are now applied following a piece-wise linear ramp, reducing the old nasty clicks, pops or zipper artifacts that might be awfully audible on some situations, most specially on automation. - All zooming in/out is now relative to either the viewport center or current mouse cursor position if found laying inside. - TYOQA! the underground sources have emerged:... after years in the making, track automation, or dynamic curves as some like to call, is finally a reality, tricky but real ;) - Audio clip anti-glitch/ramp-smoothing effect is now slightly independent of current buffer-size period (mitigating bug #3338113 effect). - Once buried under the Edit menu, Clip menu has been finally promoted to top main menu. - Debugging stacktrace now applies to all working threads. - Fixed muted loop playback on audio clips ending coincidentally with the loop-turn/end point. - Old/deprecated JACK port latency support added to audio recording latency compensation. - Audio clip merge/export lock-ups now untangled (fixes bug #3308998). - LV2 extension headers update. - Fixed configure of newer LV2 host implementation stack (LILV) when older (SLV2) is not present. Enjoy && Cheers! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

question about normalize-audio

by shane richards

After a lot of experimenting over many years, I am at a loss for how I can achieve the following (without lots of "painful experimentation"): * normalize the RMS volume of a group of samples * max value of the loudest peak in the group doesn't exceed xxx db * no limiting/clipping/compression Imagine a (non-existent) command line such as: $ normalize-audio --rms --max-peak=xxxdb --as-lossless-as-possible note that with normalize-audio 0.7.7: $ normalize-audio --peak --no-adjust $ normalize-audio --no-adjust result in exactly the same output: level peak gain -44.9045dBFS -26.6550dBFS 32.9045dB china-22in_zildjian-1.wav -36.0490dBFS -18.3966dBFS 24.0490dB china-22in_zildjian-2.wav -33.1798dBFS -14.9723dBFS 21.1798dB china-22in_zildjian-3.wav -25.6555dBFS -5.5081dBFS 13.6555dB china-22in_zildjian-4.wav -18.4676dBFS -1.4021dBFS 6.4676dB china-22in_zildjian-5.wav -17.8024dBFS -0.0540dBFS 5.8024dB china-22in_zildjian-6.wav In this case, the file with a peak of -0.054db is adjusted by +5.8db in both cases, resulting in clipping/limiting etc. Shane Richards Producer, Composer, Multi-instrumentalist Josh Music shanerich(a)email.com www.josh.com.co www.shanerichardsmusic.com

No, I can't help, I've got a RME HDSP AIO and an ADA8000 and it works at least for a test I did some time ago, didn't use this equipment until now, but I can confirm, when I turn on the Behringer additionally 8 other channels raise. Here the inputs only seem to raise, not the outputs, but the outputs do work, at least for the RME and two ADA channels. You should add information about your kernel and the version of ALSA.

J. S. Bach - 371 Chorals à 4 voix + Etudes d'anamorphoses: les différentes versions d'un choral.

by Phil Hézaine

Hello list, Created with Lilypond 2.14.1 here are two pdfs with included tar.bz2 sources .ly. For those who have problems with tar.bz2 there also are zipped sources on the site. Midi files of Lilypond were updated to take into account the duration of the fermatas, which improves the scansion of a chorale. Note however that the tempi are not relevant at all. But by changing the \guidemidi-ly in the sources you will be able to more easily produce a midi file that suits you. For those wishing a really detailed analysis of Chorales (especially the students) , I advertise them of the release: "Les colles de Bach - The Bach's School (You've got me, there)" for GNU Solfege which includes 352 chorales, each chorale being an exercise of musical dictation of 1, 2, 3 or 4 voices. All this stuff is under a Free Art License. http://superbonus.project.free.fr/spip.php?article48 Be happy. Phil.

bristol saving/loading banks

by Renato

Hello, I'm using the bristol mini moog. I saved a patch I created in an empty "program" space. However, I'd like to use this patch for a particular project, and I'm concerned that one day, using the moog for something else, I'll overwrite this patch and thus break this project. Is there a way to save and then load from command line a whole bank, i.e. all 999 programs? that way I'd save a different bank in each project directory I used bristol in and wouldn't have to worry of remembering all the program slots of all other projects or maybe it's possible to save (and then load) the current program to a file? that would actually be better cheers renato
