List of LV2 hosts, plugins and features, add yours here

by Thorsten Wilms

Hi! Plugin and host authors and those who happen to know this: please reply with at least 1 host or plugin(-set) and the provided or required features/extensions. I will then see that all that appears on the wiki. If Dave provides a template, I should be able to write the RDF files for the hosts. -- Thorsten Wilms thorwil's design for free software: http://thorwil.wordpress.com/

Re: [LAD] GMPI

by Jeff McClintock

From: Paul Davis <paul(a)linuxaudiosystems.com> > # In-place processing (reusing an input buffer as an output buffer) must be supported by GMPI. Not critical, in fact VST has removed this feature. Possible future enhancement. >say it ain't so jeff! This is a ridiculous bit of cache thrashing. I haven't followed VST carefully, and you certainly know more about it than me, but i thought that steinberg did the opposite and got rid of process_adding() and process_replacing() and required process_replacing() ("in place") semantics? Good point. In-place is super-easy to support anyhow, just use the same buffer as both input and output. Jeff

[ANN] Composite - New project for live audio sequencing

by Gabriel M. Beddingfield

I have started a new project called Composite, which is planned to be a sequencer for live-performance sequencing, sampling, and looping. One might say that it will be like Ableton Live. It will be an LV2 host for synths and effects, and will have a built-in sampler (which will probably be an LV2 plugin). At this time, the project is in the planning stages.[1] Anyone who is interested is invited to join the mailing list and share your thoughts and opinions -- especially as it relates to UI and workflow.[2] Links...... Project: http://gabe.is-a-geek.org/composite/ Mailing List: http://groups.google.com/group/composite-dev Code: http://gitorious.org/composite Specs (WIP): http://gabe.is-a-geek.org/composite/specification.html FAQ: http://gabe.is-a-geek.org/composite/faq.html Thanks especially to Patrick Shirkey for stirring things up. Peace, Gabriel CC: LAU, LAD, LAA, Composite-Dev [1] Strategy: Create a published spec. of what we want to accomplish, and then get after it. There is currently no code, but we plan to steal as much as we can. [2] However, these will probably *not* change: + Will be monolithic. Let's not start a monolithic vs. modular debate. + Will use Qt and C++.

Re: [LAD] GMPI

Can you link to an API reference or the like? Hi Chris, The download link is below. The current version is tested on Windows only, I'm pretty sure it's potentially Linux friendly because it's a refinement of the original prototype which was jointly developed with Tim Hocken on Linux. Any MSWindows-specific, or SynthEdit-specific features are implemented as extensions. I periodically check it compiles cleanly with GCC. http://www.synthedit.com/sdk.htm ----------------------------- From: Emanuel Rumpf <xbran(a)web.de> >From the KVR site: "Like MIDI, GMPI will be license free and royalty free." >"...and will cost you ~ $88 to acquire." My addition. >FLOSS people - let's rather ignore GMPI as long as we can. The prototype was developed by members of the GMPI mailing list who are not members of the MMA. "Req 113: The GMPI SDK must be released under a license with similar terms to the BSD license." It is under the BSD license, it costs nothing to acquire or to use. Every plugin I've written with GMPI (aka SEM) is also BSD and source code is available with the SDK. My own plugins are aimed at modular synthesis though, so maybe not widely useful. ------------------------------ I'm don't believe GMPI has much chance of widespread popularity, much of the design was considered too radical, e.g. my proposal to ditch MIDI. MIDI support *was* eventually included as an option, but I also support MIDI-less synths controlled via polyphonic control-ports. I will continue using my branch of GMPI, it's far cleaner, more advanced and more efficient (for me) than anything else. Here are the official GMPI requirements... http://retropaganda.info/archives/gmpi/gmpi-requirements-2005-04-05-final-dr aft.html Here (bottom of page )... list which GMPI requirements are currently supported. http://www.synthedit.com/sdk3_docs/index.htm Jeff McClintock.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm just curious what your long-time experiences with these gui-libraries are. Considering to use one of these two but can't really decide.

Re: [LAD] How to develop guis for LV2?

by Jeff McClintock

<insert obligatory GMPI joke here> >-dr GMPI is quietly and successfully in use as the new native plugin format of SynthEdit. I've so far written 70 plugins with it, and others are writing more. SynthEdit's previous plugin format has about 1000 plugins available, hopefully also will be ported to GMPI (aka SEM V3)... so GMPI can't really be called vaporware any more. Jeff

Help to choose an audio library for a project

by Ludovic RESLINGER

Hello, I'm student in computer science and for one of my projects, I would like to program an audio player. The player will be developed for GNU/Linux environment but I would like to use an audio library which permit a portability for Windows and MacOS X too. The player will must read files in wav, MP3 and OGG/vorbis (at first) and it will have an equalizer. I think to use C++ language with Qt library for the graphical interface but I encounter difficulties to make a choise for an audio library, that is why I thought to ask the question on this list. What would be the best audio library to program this kind of audio applications ? (SDL ? OpenAl ? PortAudio? or other(s) ?) Thank you by advance for your answers. Regards, -- .---.

LV2 compliant tests

by Machel Sylvain

Hi, I'm about to work on a LV2 wrapper for the FxEngine Framework and I would like to know if it exits compliant tests to validate LV2 plugin according to the port type, scope, ect ..... ? With the exeption of a few unitary tests, I didn't find anything on the web. Thanks in advance, regards, Sylvain
