[ANN] Qsynth 0.3.6 slip release!

by Rui Nuno Capela

Season greetings! It's spring-cleaning time once again. Dust has severely piled up and brand old mite is already lurking around. That's the bad news. Good news are there are plans for this FluidSynth gooey front-end, you know it's about Qsynth. Alas, plans are follow today's "slip release" though. Finally, you may say. Not that there's any big (not even small) new features being slung out today. In fact, there's just a lousy couple of the same old crap. Never mind. Big plans are all about getting some channel controllers--also known as generators--into the picture. Yes, finally. It means amplitude, filter envelope generators, LFO modulators, knobs and sliders gore fest and what not. I hear you thinking that's all what a synth is about. And you're damn right. Dropping an initial, "synth" has been in the name all this time hasn't it? Right, it has been a pretty old plan, ever since early dawn. Well, it still is... a plan. As always, I won't make any promises, which would be a terrible thing to do, specially from one who keeps calling himself the "über-procrastinator". Yeah, I'm sure you know me from previous auto-proclamations. Back to subject at hand, there it is. Qsynth 0.3.6 slipped away from the dust! Website: http://qsynth.sourceforge.net Project page: http://sourceforge.net/projects/qsynth Downloads: - source tarball: http://downloads.sourceforge.net/qsynth/qsynth-0.3.6.tar.gz - source package (openSUSE 11.4): http://downloads.sourceforge.net/qsynth/qsynth-0.3.6-2.rncbc.suse114.src.rpm - binary packages (openSUSE 11.4): http://downloads.sourceforge.net/qsynth/qsynth-0.3.6-2.rncbc.suse114.i586.r… http://downloads.sourceforge.net/qsynth/qsynth-0.3.6-2.rncbc.suse114.x86_64… - binary packages (Windows): http://downloads.sourceforge.net/qsynth/qsynth-0.3.6-setup.exe Change-log: - Main window layout fixing with regard to its user preferred size and recall when system-tray icon is not enabled. - Channels list preset items now activated on double-click. - Desktop environment session shutdown (eg. logout) is now tapped for graceful application exit, even though the main window is active (visible) and minimizing to system tray is enabled. Both were causing first shutdown/logout attempt to abort. Not anymore, hopefully ;). - libX11 is now being added explicitly to the build link phase, as seen necessary on some bleeding-edge distros eg. Fedora 13, Debian 6. - General standard dialog buttons layout is now in place. - CMake build system. It was silently available in 0.3.5, but now it is officially unveiled. - Fixed a couple of dangling pointers. - Mac OSX: Enabled the MIDI name Id option for CoreMIDI driver ports, added the icon to the app bundle. Weblog (upstream support, yours truly): http://www.rncbc.org License: Qsynth is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Petri-Foo first release

by James Morris

Hi, Petri-Foo is a fork of the Specimen sampler project created in February 2011. The first source-code release of Petri-Foo is now available to download and build and is available directly from: http://sourceforge.net/projects/petri-foo/files/Source/petri-foo-0.0.1.tar.… Many of the features of Petri-Foo are almost identical to Specimen except: Modulation: * decoupled LFOs and Envelopes from parameters (modulation sources can be chosen independently for each parameter). * LFOs themselves can be frequency modulated * Keyboard tracking. Sampler: * improved sample viewer * improved drawing code using Cairo * faster waveform drawing after window damage. * additional 'to end' playback option. * fades for playback and cross-fades for looping Voice: * improved mono/legato operation * improved envelope behaviour for mono/legato operation Plus many other changes less visible to the user. Petri-foo is not well tested at all. Part of the purpose of this release is to hopefully find users to test Petri-Foo and to report bugs and other problems, and ideas for continued development. More information for those interested can be found on the Petri-Foo homepage. The Petri-Foo homepage can be visited at: http://petri-foo.sourceforge.net/index.html Cheers, James.

Sek'd Prodif 96

by Reid Fletcher

I have a couple of sound adapters labeled Sek'd Prodif 96 They are known to be a good card. However I have been unable to find any drivers for Linux for these. I have not been able to find a Users Manual either. Does anyone have any information regarding these cards? I would like to use them on either an OpenSUSE 11.2 or Ubuntu 10.04 system running Rivendell if possible. __Reid__ Reid Fletcher, WB7CJO

Good Mixer Library

by Gerald Mwangi

Hi, I'm messing arround with the source of TerminatorX. As it seems, tX needs a total rewright of the mixer and the audio backend. Since many programs (Ardour, Qtracktor) have built mixers, I was wondering from which project I could 'borrow' the mixer component. I need a mixermodel which is strictly C++, which idealy has jack support built in, possibly multithreaded, GUI-Independant and easy to handle. I started to wright my own mixermodel, but then I thought how stupid it is to reinvent the wheel. It would really be nice something like a libmixer with jack, lv2, ladspa and VST support. Gerald
