dssi-vst 0.3 released! ====================== The 0.3 release of dssi-vst is now available. dssi-vst is a DSSI plugin wrapper for VST effects and instruments with GUI support, allowing them to be loaded into any DSSI host. It requires a fairly recent version of Wine (this calendar year at least). dssi-vst is available from the download page at http://dssi.sourceforge.net/ The main improvement since the initial 0.1 release is that dssi-vst now works correctly with plugins with complex GUIs that use back-channel information to communicate things like patch data to the audio plugin. In practical terms, this means that VSTs with test keyboard widgets, patch load and save, and other natty features in their GUIs should work properly as DSSI plugins without losing automatability for the true automatable parameters.

[linux-audio-dev] [ANN] libDSP-5.0.0

by Jussi Laako

OK, a new stable release after a long while... This one has loads of new stuff vs previous stable. libDSP is a C++ library of digital signal processing functions. It also contains a wrapper for C. Assembler optimizations for E3DNow!, SSE2 and x86-64 (SSE2). Either http://libdsp.sf.net or http://www.sonarnerd.net/projects/libdsp/ -- Jussi Laako <jussi.laako(a)pp.inet.fi>

[linux-audio-dev] [RFC] C++ wrapper for JACK API

by Jussi Laako

I believe there are many C++ implementations of JACK API, but I'll add my 50 cents to the game anyway. I created this for my own applications, and this is very new and untested piece of code. Anyway, I welcome any comments on this and hopefully this code could be useful to someone else too. A basic JACK application made using this library works OK anyway. Current implementation is available from: http://www.sonarnerd.net/linux/libjackmm-071104.tar.gz -- Jussi Laako <jussi.laako(a)pp.inet.fi>

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

[linux-audio-dev] [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-dev] [ANN] DSSI 0.9 released

by Chris Cannam

DSSI v0.9 released ================== I'm happy to announce version 0.9 of the DSSI plugin API. http://dssi.sourceforge.net/ DSSI is an audio plugin API designed for software instruments with custom user interfaces. DSSI is based on the LADSPA effects plugin API, the ALSA sequencer event types, and OSC (Open Sound Control) communications. It's intended to be easily understood, GUI-toolkit-agnostic, and slightly biased towards familiarity with MIDI. The DSSI distribution package contains a JACK/ALSA-sequencer reference host and some plugins as well as the specification and header. DSSI 0.9 was constructed by Steve Harris, Chris Cannam, and Sean Bolton. New in 0.9 ---------- The main improvements in 0.9 are to the reference host implementation and sample plugins. The 0.9 API itself is binary compatible with the previous 0.4 release. A new convention for plugin-global (rather than instance-local) configuration data and a convention for setting a plugin's project working directory have been introduced, and 0.9 clarifies certain implementation points in the documentation. Available hosts and plugins --------------------------- Two hosts are currently known to include complete or nearly-complete DSSI support: the reference jack-dssi-host included in the DSSI 0.9 distribution, and versions 0.9.9 and later of the Rosegarden-4 sequencer. Currently available plugins include: * a FluidSynth soundfont plugin included in the DSSI distribution * Xsynth-DSSI, an analog-style (VCAs-VCF-VCO) plugin * dssi-vst, a wrapper plugin enabling the use of many Windows VST instruments and effects * hexter, a Yamaha DX7 modeling plugin * three smaller example plugins (two synths and a sampler) that are also part of the DSSI distribution.

[linux-audio-dev] calling open source artists/musicians (UK London area)

by Dave Griffiths

Hi all, A couple of us are thinking of putting together an open source focussed music and visual performance night in London (UK), with the aim of making it a semi regular event with a bit of a workshop feel to it - so people can share ideas and have some fun. We're just wondering what the interest for such an event would be, whether people would be interested in participating, or indeed if there is already something going on we've missed. Also if people are already doing similar nights in other places, if you have any tips. You can contact us directly at: leechun(a)leechun.freeserve.co.uk dave(a)pawfal.org or reply to the list... cheers, dave
