[linux-audio-user] Any useful Supercollider sites?

by Mark Knecht

Hi, OK, I'm really proud that I got SC installed and running the one little demo that came with the program. It makes a few notes looping with a filter being swept. Cool! Now, I just want to use SC as a synth to start. Does anyone know of even a single good site with downloadable examples that I can run and play around with to start? I was very impressed with a couple of the mp3 examples on the SC site itself, but disappointed that nothing much came in the build of SC itself. Of most interest are examples that take MIDI input, but repetitive things like drones, etc., are really cool too. Thanks in advance, Mark

[linux-audio-user] Fwd: [linux-audio-dev] QSynth/fluidsynth having problems with looped soundfonts

by Rui Nuno Capela

Hi, (Cross-posting to fluid-dev list, just in case someone is listening there too, and have some comment into play) I don't seem to notice this behavior, but strange enough, I don't have that many soundfonts to try. Maybe if you point us a specific soundfont file (url?), bank and program numbers of the patch where the issue is exposed... Probably not on time for your presentation, but I would like to confirm whether it's an internal fludisynth bug (qsynth is just a Qt frontend to libfluidsynth) or a side-effect from from your ecosystem. Distro and fluidsynth/qsynth versions would be welcome for the record. If you compiled from source, the configure command line optimization options are known (by just me?) to have a relevant impact to the fluidsynth build stability and behavior. Just check it out. Bye now. ---------------------------- Original Message ---------------------------- Subject: [linux-audio-dev] QSynth/fluidsynth having problems with looped soundfonts From: ico(a)fuse.net Date: Wed, November 3, 2004 4:12 -------------------------------------------------------------------------- Hi all, Just a quick question before my tomorrow's presentation. I am hoping to be able to present fluidsynth/Qsynth but one of the issues I encountered using two different versions of fluidsynth and a number of soundfonts is that the sound of soundfonts is fine until they begin to loop (i.e. long flute sound eventually starts to loop the sample) and then at every loop cycle there is a kind of a clicking noise as if the loop points are either badly designed (unlikely, since I tried 5 different soundfonts that were downloaded from different places), there is something weird with the tested versions of fluidsynth, or this is a bug? Any help is greatly appreciated! Best wishes, Ico

Re: [linux-audio-user] Hi All!

by Brian Redfern

I use mostly csound under linux, and in deferred mode. Once I can get csoundVST running under linux, then I plan to use the python api to glue it into the python OSC library and then use open sound control to create what I'm conceptualizing as a kind of teleprescense jazz, electronic improvisation, where I can send the app to the location and then control the performance remotely with OSC. First I have to figure out which version of Portaudio I should be using with csoundVST, I've tried to get it running under both windows and linux and have so far failed, but I have to keep trying cause I can't wait till I can write my own extensions to the python lib.

[linux-audio-user] creating harmony files ( 3rd, 4th, 5th)

by ed orphan

Can you create a file that is the 3rd, 4th, or 5th harmony to another file using Sox or ecasound? I've got a nice riff in the file riff.wav and I'd like to create some files that are in harmony to that file. So I'd have a file called riff_3.wav that would be in 3rd harmony to the riff.wav, and one called riff_4.wav that would be in 4th harmony, riff_5.wav, etc. Then I'd like to combine these files in various ways to create an output.wav. just to experiment and see what happens. Can you do this using Sox or ecasound? Could anyone tell me how, or where I could get some examples or more information on how to do this?

[linux-audio-user] suggest a synth

by vord

hello list. ive somewhat recently begun composing, and also experimenting a little with sound in linux ... so far though i only have a schumann baby grand piano and this gentoo linux workstation. i decided earlier this week to branch out a bit and purchase a synthesizer; and i figured i should poll this list for suggestions. my budget is pretty slim though ... $500 max. new/used ... new/old ... analog/digital ... doesnt really matter to me. i just want rich sounds and plenty of knobs for twiddlin'. :D suggestions? --vord

[linux-audio-user] Sox compand segmentation error

by ed orphan

Can anyone give me a working example of the Sox compand command? The one in the Sox examples ( man soxexam ) does not work on my machine. Everything else works and it's great to have these examples or I'd never figure it out on my own. All I need is a working example of how to expand and how to compress using Sox and I'd be very pleased. This is what does not work: As root, using OSS play my.wav compand 0.3,1 -90,-90-70,-70,-60,-20,0,0 -5 0 0.2 The wav file is 16-bit, 2 channel, 44100 Hz The error message is: /usr/bin/play: line 205: 1576 Segmentation fault sox $volume $fopts $fopts2 "$filename" $arch_defines $device $effects duh? Anybody know how to fix this?

[linux-audio-user] RE: [Rosegarden-user] advice for beginner?

by Alejandro Lopez

Hi Hamish, >I'm currently trying to choose between Mandrake and Ubuntu Linux, >both of which look suitable for a non-tech-minded person like myself. I would recommend installing a DAW oriented distro. Demudi has been recommended in the different forums as the easiest way to setup a studio. The reason is that all other music oriented distros (Planet CCRMA, Thac's packages) need to be installed on top of a general purpose distribution. I've recently installed Demudi and it's been a painless proccess generally. It's based on Debian, so you can add general purpose packages to your "audio PC" at a later date. >And how far off is the 1.0 release for Rosegarden? According to the website, it's happening very soon.. >And are there are any performance oriented apps for Linux similiar to >Ableton Live? Dunno, but I can recommend this forum for this kind of info, it's great: http://www.music.columbia.edu/mailman/listinfo/linux-audio-user/ Also could be of help for making a final decision on which distribution to install..

[linux-audio-user] [ANN] hexter DX7 modeling DSSI plugin

by Sean Bolton

Announcing the first public release of the hexter DSSI plugin. http://dssi.sourceforge.net/hexter.html hexter is a software synthesizer that models the sound generation of a Yamaha DX7 synthesizer. Now you can have the sparkling, richly evolving sounds of this classic FM synth on your Linux workstation! There are a few things still missing from hexter's emulation of the DX7 (and it doesn't attempt more general FM synthesis like Native Instrument's FM7), however, even at its current stage of development, it is quite useable and recreates the sound of the DX7 with greater accuracy than any previous open-source emulation (that the author is aware of....) It can easily load most of the thousands of DX7 patch bank files available on the Internet, and can accept patch editing commands via MIDI sys-ex messages from your favorite DX7 editor/librarian. hexter operates as a plugin for the DSSI Soft Synth Interface. DSSI is a plugin API for software instruments (soft synths) with user interfaces, permitting them to be hosted in-process by Linux audio applications. More information on DSSI can be found at: http://dssi.sourceforge.net/ The latest hexter version (currently 0.5.7) can be obtained at: http://sourceforge.net/project/showfiles.php? group_id=104230&package_id=134428 hexter requires a working DSSI host, liblo, GTK+ 1.2.x, plus the ALSA headers and LADSPA SDK. hexter is written by Sean Bolton, and copyright (c)2004 under the GNU General Public License, version 2 or later. hexter benefited greatly from previous open-source efforts, most notably Juan Linietsky's rx-saturno, and FluidSynth by Peter Hanappe, et al.

[linux-audio-user] Noob question about soundfonts & synths

by Mark Wilson

Looked at hammersound.net, downloaded a couple of .sf2's, successfully loaded with qsynth, played with cool sounds in rosegarden4 and with plain ol' pmidi on the CLI. Having lots of fun! :-D The question: what's a pad, in the context of softsynths? TIA, Mark ===== -- Seek professional help!
