Hi all (especially Fons!)! I've just successfully compiled and installed aeolus (lastest release). I can start the program connect it to jack and alsa midi seqeuncer, but there it stops. I asked a seeing companion of mine to have a look at the ui, but even after pressing several buttons, there was no sound. Now my questions: 1. Is this a bug or just me and my friend being to stupid? 2. Are there shortcuts/hotkeys, so I can use the organ myself without help? 3. Are there maybe other ways to use it vai "remote control" (OSC, etc.)? I'm greatful for any good suggestions and hints! Kindest regards Julien P.S.: I read the installation instruction and directory/configuration hints very carefully, it shouldn't be that... :-) -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net - the Linux TextBased Studio guide

[linux-audio-dev] Job openning

by Eric Dantan Rzewnicki

Attached is a pdf containing the job announcement for Director of Technical Support at Radio Free Asia. We use Linux and Free Software for most of our network information systems and also for a number of middleware applications that glue together our various proprietary audio systems. We also have users beginning to test Audacity as a replacement for Cool Edit. In the future I see a place for Ardour as a replacement for our 30+ aging Orban Audicy(tm) DAWs, Audacity as a replacement for Cool Edit, icecast/ogg-vorbis/ecasound to replace our hardware mp3 encoders for streaming and archiving and perhaps other uses of linux audio software as well. Address any replies to jobs(a)rfa.org Thanks, -- Eric Dantan Rzewnicki | Systems Engineer I Technical Operations Division | Radio Free Asia 2025 M Street, NW | Washington, DC 20036 | 202-530-4900 CONFIDENTIAL COMMUNICATION This e-mail message is intended only for the use of the addressee and may contain information that is privileged and confidential.

[linux-audio-dev] [ANN] blepvco 0.1.0 - LADSPA minBLEP hard-syncable VCOs

by Sean Bolton

Announcing blepvco 0.1.0: http://home.jps.net/~musound/blepvco-0.1.0.tar.gz blepvco is a LADSPA plugin library containing three anti-aliased, minBLEP-based, hard-sync-capable oscillator plugins. The oscillators are intended to be used with modular synthesis systems, such as Alsa Modular Synth (a couple example AMS patches are included). The three oscillators are: Sync-Saw-VCO : Anti-aliased sawtooth oscillator with hard-sync capability Sync-Rect-VCO : Anti-aliased variable-width rectangle oscillator, with sync Sync-Tri-VCO : Anti-aliased variable-slope triangle oscillator, with sync Users of Fons Adriaensen's VCO-plugins will find these plugins immediately familiar, since they borrow much of their interface code from Fons' work -- indeed, if/when you do not need the hard-sync or variable-slope triangle wave features of blepvco, his plugins may be a better choice, because their CPU use is somewhat lower. Currently, his VCO-plugins can be found at: http://users.skynet.be/solaris/linuxaudio/ blepvco is written by Sean Bolton, and copyright (c)2005 under the GNU General Public License, version 2 or later. Much thanks to Fons, Daniel Werner, Tim Stilson and Julius Smith, and Eli Brandt.

[linux-audio-dev] the best playback/DAC card

by Andrew Gaydenko

// Sorry for crossposting, I have got the only reply at the LAU list :-( Hi, Will be glad to get your opinions about choosing an audio card below $250. The main (and, probably, the only) planned using is a playing back of stereo files. Probably, a DAC quality is the main feature here. With hope, Andrew

[linux-audio-dev] problem with jack_fst + qjackctl

by Dave Phillips

Greetings: When I use jack_fst with the Crystal synth it works fine, but when I close the plugin qjackctl closes too. Its settings remain in effect, but the GUI vanishes. If anyone else has this problem, please let me know if you've found a fix for it. It's annoying to have to reopen qjackctl each time I use jack_fst. jack_fst 1.2, qjackctl 0.2.14 Best, dp

[linux-audio-dev] Acceptable MIDI data rate?

by Darren Gibbs

I meed to communicate with MIDI devices from an embedded Linux world (Gumstix). Its UARTs are cabable of: 14.7456M/16*29 = 31779 14.7456M/16*30 = 30720 MIDI spec says +-1%. My error is 1.7%, Is this close enough? I figure this problem can't be new, but I'm finding very little info about it. Some sites hint that an error of up to 3% is OK with certain MIDI devices. Any advice appreciated, darren

[linux-audio-dev] Mx41 update

by Jens M Andreasen

Mx41 minor update at http://hem.passagen.se/ja_linux This wasn't on my todo list, but I just stumbled over the missing link in the voice assign/stealing algorithm and couldn't help implementing it. Just to check out if it really worked ... and I think it did :) I now have voices in five assignment-ques: silent // absolutely idle voices released // voices about to become idle excess holdpedal // elder voices than mentioned below .. holdpedal // the two most recent voices for a given key fingered // voices where the key is still pressed ... and a short two-voice que for each key to figure out the 'excess' part. Voice assign will at best find a silent voice and at worst a fingered voice. Rolls (tremolo?) now works proper without stealing highest or lowest note, nor anything inbetween for that matter. Finally! Is there room for improvement? Yes I think so ... It is now possible to get 'clicks' with certain combinations of envelope and playingstyle. On the other hand it is also quite easy to avoid, so I will work slowly on this one. -- ( ) c[] mvh // Jens M Andreasen

[linux-audio-dev] So difficult

by Juhana Sadeharju

Hello. It is no problem to design or write reverbs. The problem is in coding the interface (API, GUI, etc.) to the reverb. Here are some numbers. Yet unreleased jackgverb source code has 20 parameters, and I have coded only the early reflection section. All 20 parameters are meaningful to the end users, i.e., they are not developer parameters such as lengths of individual delay lines. Therefore the number of parameters cannot be reduced without making the reverb dull, canned. For each parameter I have the following functions: -a GUI callback (e.g., slider) -jackgverb_set() and jackgverb_get() called in the GUI callbacks -gverb_set() and gverb_get() called in jackgverb_set/get() Perhaps jackgverb_set/get() are unnecessary. I have them because gverb is an enclosed system with API and if I need to add something to the jack wrapping, its place is in jackgverb_set/get(). So, in total I have 5*20 = 100 functions for the parameters. The whole situation is a nightmare. I don't have time nor interest in coding with that kind of system. It all gets worse if the design is changed as often happens in the design phase. What would help? If nobody figures out anything, I could draw the reverb design on a small piece of paper and then somebody else may torture himself in coding. Are there coding patterns which would make my C code simpler? Would modular system help? PD has strange firing rules: does they apply to standard signal flow or to advanced ones? Feedback paths should be sample accurate, not blocked to N samples as in Csound.
