Nekosynth, GPL, and commercial and non-commercial use.

by Gordon JC Pearce

Just to clear up a few recent misunderstandings that have been aired on the list, I'd like to clarify my position on the various nekosynth plugins (that is, nekobee, nekostring, nekoplunk, the organ, and the as-yet unreleased and waaay unfinished Hera plugin): You may use these plugins in accordance with the GPL for any purpose. If you want to produce a piece of commercial hardware that utilises a version of my plugins, that's fine - but I'd like you to send me some demo hardware. Toys are good, and you can be sure that your hardware will always be supported by the freshest versions of the software. You may use these plugins on any recording, commercial or non-commercial. If you make a shitload of money from a record where you use one of my plugins, I'd like it if you mention me on your website or maybe somewhere in the sleeve notes. If you could see your way clear to providing a short demo (30 seconds or so) that would be really great, and will earn you the right to ask for special custom versions. You may sell copies of the software, as long as this complies with the GPL. In general, include the source if you've modified it, and leave my copyright message in. Simple, eh? On the subject of selling software, I'd like to offer the following range of products. For £5/6.75EUR/US$10 you can get all the nekosynth plugins, in their current state, on a CD. Not only that, but I'll throw in the full Subversion dump, all tagged-stable tarballs (even from before I was using svn), and the demo tunes. For £25/33EUR/$50, you can get the nekosynth Producer Pack, which comes with some drum loops and six cans of McEwans Export. For £50/66EUR/$100, you get nekosynth Studio Edition, which comes with the drum loops, 12 cans of Deuchars IPA, and some random electronic components I hoovered up off the floor in my studio. For £750/1000EUR/(not applicable in US markets) you can get nekosynth Super Mega Fun Box edition, which comes with the drum loops, a Cheetah Telecaster copy, and a 1993 Ford Escort with six month's tax and a year's MOT (but no beer, because we can't possibly encourage drink-driving). Finally, for the true enthusiast, you can order the nekosynth Ultimate Eternal Natural Beauty edition, for the low, low price of £36,000 (not available outside UK). This has the full source tree, CNC-milled onto 8'x4' slabs of natural Ballachulish slate, packaged in mahogany presentation cases, and a free Leyland Roadrunner 7.5 tonne truck to ensure that you can take your copy of the source code with you wherever you go! Now you can't say any fairer than that, can you? Gordon

LinuxSampler or JACK or what is the trouble?

by Julien Claassen

Hi everyone! I've still got some problems with my LS. I can load smaller gigsampler (upto 650M for sure) and even larger ones, bUT... But when I load my Old Lady Grand (1.3G) it loads perfectly, but when I try to connect LS to JACK the following happens: [Linuxampler console] [copeous output] Caching initial samples...OK cannot complete execution of the processing graph (Resource temporarily unavaila ble) zombified - calling shutdown handler Killed [JACK console] [copious output] Noise-shaped dithering at 16 bits jackd watchdog: timeout - killing jackd Aborted what's the trouble. I just compiled JACK 0.109.1 (svn from 29.01.2008) and LS 0.5.1 (tarball). My kernel is: host # uname -a Linux bach 2.6.23.1-rt11 #2 PREEMPT RT Sun Dec 30 22:43:22 CET 2007 i686 GNU/Linux I've got 512M RAM (no Xserver running), so mostly unused. I compiled my LS with 8 diskstreams min and 140 max, and max 128 voices, the rest was decided by the configure script. I even tried reverting the disk-stream options and the voices to normal. Jack was compiled without a lot of drivers I don't need, and with --enable-resize --enable-timestamps --enable-sse --enable-mmx --enable-optimization-by-compiler I start my jackd with: jackd --timeout 4000 -R -d alsa -d hw:1 -r 48000 -H -M -p 256 -z shaped I've got a 1.8Ghz CPU and my soundcard is an MAudio Delta 1010LT. One last note: I checked memory sage with top: Even with the big gigasample it only takes 41% and CPU-usage is marginal. So where would you suspect the most possible source for my problem?

[REMINDER] A bit of common sense.

by Marc-Olivier Barre

Hi, May I remind all of you of a few facts : - We have currently 736 members on this list. Those of you math lovers will have guessed that sending an email to this list implies having (736 - number who have disabled mail delivery ~= 700) receipients. - When one of you sends bull crap on this list, 700 people can have the pleasure of receiving (reading?) it. - When someone flames over a topic that has been debated countless times, without reaching an interesting conclusion, I would say at least 600 people would have rather read the old arguments in the archives. You might also want to read the Linux Audio Dev's homepage : http://lad.linuxaudio.org/subscribe/lad.html Interesting quote : "The Linux Audio Development Mailing List is unmoderated. No matter what you post, the list will see it. Please take responsibility, keep your postings on topic and help maintain the friendly and respectful atmosphere that we have here" Thank you to keep those in mind when posting. __________________ Marc-Olivier Barre, MarcO'Chapeau.

I wonder about making some faust inspired macros for snd-rt to make user interfaces more integrated. I think the snd-rt program below should do the same as the faust version now, although I'm not too sure about the correctnes of the delay interpolation and filtering. They both sounds the same though, I think: (set! (rt-safety) 0) (definstrument (line n dialog) (let ((del (make-delay 1 :type mus-interp-lagrange :max-size 20000)) (length (make-glide-var 0 100)) (gain (make-glide-var 0 0.005))) (<slider> dialog (<-> "gain " n) 0 0 2 (lambda (val) (write-glide-var gain val)) 100) (<slider> dialog (<-> "delay " n) 1 1 20000 (lambda (val) (write-glide-var length val)) 1) (<rt-play> (lambda () (set! (mus-length del) (read-glide-var length)) (out 0 (* (read-glide-var gain) (delay del (in 0)))))))) (letrec* ((exit (lambda () (rte-silence!) (-> dialog hide))) (dialog (<dialog> "Delay line stuff" exit " exit " exit "Stop" rte-pause "Start" rte-continue))) (for-each (lambda (n) (line n dialog)) (map number->string (iota 10))) (-> dialog show)) The faust program uses 2.1% percent cpu on my xp2800, while the snd-rt program now uses 3.8% percent cpu. The reason for the speed increase for the snd-rt program is because the scheme list traversals and vector accesses is removed from the dsp code. Instead the scheduler just runs 10 realtime instances. To run the program, just paste the code above into snd-ls' terminal.

JACK 0.109.2 released

by Paul Davis

This is a maintainance release of JACK. Three important issues are fixed: * the old ALSA PCM port names are available, so that applications that either hardcode or have existing patching information containing these names will function. * the use of popen(3) to invoke jackd to determine the server directory has been fixed so that it works on systems that have closed a security risk with popen(). This was preventing correct startup on OS X, in particular. * USX2Y driver updates to enable JACK MIDI devices to show up in raw-usb mode (previously, raw-usb mode didn't initialize or call MIDI drivers properly). Download from either jackaudio.org or sourceforge: http://jackaudio.org/downloads/jack-audio-connection-kit-0.109.2.tar.gz http://prdownloads.sourceforge.net/jackit/jack-audio-connection-kit-0.109.2…

Ah, so that what was funny. But nothing from Dave or me was funny. So apparently you have humour, but we don't. Now you are explaining your oh so clever argument again an again. That's just sad.

Fwd: LS licensing (was: LV2 " isn't well thought out ?" LV2 in the Reaper sequencer)

by alex stone

Hehe, succinctly put Christian. Just doing a quick count of all the lines that have been written about this, and the sometime belligerent enthusiasm attacking LS and questioning their integrity because they're perceived as not being 'pure' by interpretation, by some of you, and just since i've been here, there seems to be a lot of code, sorry i mean text, written. Makes me wonder just what the incentive is, to batter this to death over and over again, instead of being admired for the quality and skill of coding most of you have already proved you are capable of. To offer a counterweight to this, have all you craftsmen considered getting together in a concentrated team effort, free of politics, and indulge in an intense push to expand Jack and Jackdmp (for example) to incorporate kernel level audio, with modules, and do away with alsa altogether? Now that WOULD be something to talk about, and a wonderful incentive for developers to come together as one, with a common goal for the greater good. Jack is already 'king of the empire', in my humble opinion, and would expand it's grip on the planet even further with this final step towards ONE complete linux audio and midi solution. I live in hope that you chaps will take a deep breath, and use those obviously competent typing skills you're exercising at the moment, in writing more excellent code that i can use, and continue to admire and respect you for.

Abstraction for JACK control API

by Nedko Arnaudov

After some discussion on IRC with Stéphane Letz, I created abstract description of the API that is needed to implement current jackdbus functionality (i.e. without the coming patchbay and transport control interfaces). I've decided to describe it in C++ just because it will be more clear to general public than plain C OO abstraction, or UML diagram. jackdbus code itself is in plain C. Hope is that such abstraction will help to have same D-Bus interface implemented (and much of related code - shared) for both jackd and jackdmp. // -*- Mode: C++ ; c-basic-offset: 2 -*- /////////////////////////////////////////////////////////////////////////////// // // DESCRIPTION: // Abstraction of the API needed to implement jackdbus // /////////////////////////////////////////////////////////////////////////////// #ifndef JACKSERVER_H__775F79BA_DDE0_4FEA_AC4B_7BE05638499C__INCLUDED #define JACKSERVER_H__775F79BA_DDE0_4FEA_AC4B_7BE05638499C__INCLUDED /** Parameter types, intentionally similar to jack_driver_param_type_t */ typedef enum { JackParamInt = 1, JackParamUInt, JackParamChar, JackParamString, JackParamBool, } jack_param_type_t; class ImmutableString; class ImmutableVariant; template<class T> class ImmutableSet; class JackConfigurationParameter { public: ImmutableString& GetName() const; ImmutableString& GetShortDescription() const; ImmutableString& GetLongDescription() const; jack_param_type_t GetType() const; ImmutableVariant& GetValue() const; void SetValue(ImmutableVariant& value); }; class JackConfigurationDriverParameter: public JackConfigurationParameter { public: bool IsSet() const; ImmutableVariant GetDefault() const; }; class JackConfigurableObject { public: virtual ImmutableSet<JackConfigurationParameter>& GetParameters() const = 0; // helpers JackConfigurationParameter& FindParameter(ImmutableString& parameter_name); }; class JackDriver: public JackConfigurableObject { }; class JackEngine: public JackConfigurableObject { }; class JackServerInterface: public JackEngine { public: ImmutableSet<JackDriver> GetAvailableDrivers(); void StartServer(JackDriver& driver); // next ones are called only on started server void StopServer(); double GetLoad() const; // In percent unsigned int GetSampleRate() const; // in Hz double GetLatency() const; // in milliseconds bool IsRealtime() const; // whether engine is running unsigned int GetXruns() const; void ResetXruns(); // reset value being returned by GetXruns() to 0 }; #endif // #ifndef JACKSERVER_H__775F79BA_DDE0_4FEA_AC4B_7BE05638499C__INCLUDED -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

Geez, you guys are really winning me over. It's the good right of Dave and Lars to not care or even outright reject closed software. They could have said it more diplomatic terms ... but now you make a drama of it. It could even be that both never claimed to be open minded ;) Dave puts an incredibly amount of effort into several open projects. Why would he go out of his way to help adding capabilities to closed software that kinda competes with what he works on? Producers of closed software gotta love competition and doing it all by themselves. > No fear, no-one's going to ask you or DR for help in this matter. There are very few others who could help in this matter, so what do you think you gain with this confrontative behaviour? Now you could say going to that forum and correcting misconceptions regarding LV2 should be easy enough and worth it, but even that eats time of which there is so little in a day. Plus to me it sounds like that guy doesn't want to get it. -- Thorsten Wilms Unbegrenzter Speicher, Top-Spamschutz, 120 SMS und eigene E-MailDomain inkl. http://office.freenet.de/dienste/emailoffice/produktuebersicht/power/mail/i…
