Hey all: Even though I didn't get it done in time for the great linux audio release day earlier this week (fondly known as the big L.A.R.D), I hope this offering of free freedom will still be accepted. I found some flaws in the voice deactivation improvements from the last release, especially if using a patch with a long release (which I hadn't before). As part of this, I've removed a few loops in the code so there may be some small amount of performance gain. In addition this release adds a couple patches (with long releases surprisingly). It is recommended all users and packagers upgrade asap. Enjoy! https://github.com/ssj71/reMID.lv2/releases/tag/v0.3 <https://github.com/ssj71/reMID.lv2/releases/tag/v0.2> reMID is a MIDI implementation of a MOS8580/6581 SID chip (Commodore64) using the reSID library. It includes support for scripted instruments that allow complex sonic control of the chip.

[ANN] jack-select 1.3.0 released

by Christopher Arndt

Griaß enk! a new version 1.3.0 of *jack-select* has just been released! What is it? *jack-select* is a systray app to set the JACK configuration from QjackCtl presets via DBus. It displays an icon in the system tray of your desktop, which shows the status of the JACK audio server and when you click on it, a menu pops up, which lets you quickly select from the JACK configuration presets you created with QjackCtl. This allows you to switch between different audio setups with just two mouse clicks. *jack-select* works with the DBus-version of JACK only. It is written in Python 3 using the ``PyGObject`` bindings for GTK 3. Python 2 is not supported. What's new? Yesterday's 1.2.0 release unfortunately has some issues handling some variants of the presence or non-presence of the '(default)' preset in QjackCtl's configuration. This release attempts to fix those and introduces a few new options, hence the increase of the minor version. * Added command line option -i, --ignore-default to ignore the '(default)' preset if any other presets are stored in the QjackCtl configuration. * Fixed handling different variants of the presence / non-presence of the '(default)' preset when reading the QjackCtl configuration. * Added command line option --version to show the program version. * Updated the UNIX manual page. Where to get it? https://github.com/SpotlightKid/jack-select or via pip (but see the "Requirements" section in the README first): pip install jack-select or, for Arch Linux users, from the AUR: https://aur.archlinux.org/packages/jack-select/ How to use it? Please see the README file here: https://github.com/SpotlightKid/jack-select/blob/master/README.md *Share & Enjoy* Christopher Arndt

Wolf Spectrum - Spectrogram plugin (LV2/VST/Jack)

by Patrick Desaulniers

Wolf Spectrum is a free, real-time spectrogram plugin. It can be used to analyze the frequency content of signals over time. Right now, it supports vertical scrolling, logarithmic/linear frequency scaling, and configurable block sizes. I plan on adding a few features in future releases, such as horizontal scrolling and the ability to show the frequency at the cursor's position. To install the plugin, follow the instructions in the README: https://github.com/pdesaulniers/wolf-spectrum If you encounter some issues with the plugin, please report them. Feature requests are also welcome :) Thanks!

Infamous Plugins v0.3.0 The Never had a Summer of '69 Release

by Spencer Jackson

Yo: Keeping up with the cool kids, infamous plugins will be participating in quarterly releases (or at least I'll be releasing at least one of my projects each quarter). This is beneficial because it forces me to release "small" fixes regularly, rather than waiting for the "BIG" release I had in mind (that's going on nearly 2 years and counting). So wrapped into this release is lots of touch-ups and small fixes that mostly affect the host integration to the plugin. More notably the infamous stuck algorithm received a lot of attention and polished up as much as possible (probably no noticeable change to anyone though), a new stuck stacker version was created with no dry signal output so you can have several in parallel without affecting the gain, and the infamous power-up no longer has 10 seconds of latency (latency will now equal the power-up time). The biggest addition though in this release is (fanfare): the infamous octolo. It's an octaver and tremolo in one (see what I did there?). It works as a fairly nice sounding tremolo too but the special sauce is that it is able to play different sequences of the 3 voices (octave up, octave down, same octave) for some fun rhythmic effects. Basically I keep trying to chase low-CPU pitch shifting and this is my latest solution. By using the tremolo effect for silent jumping, I'm able to play back the sounds at different speeds to achieve an octave up and octave down effect. At long tremolo lengths (slow speed) you will notice the timing effects which may make it a bit unwieldy for certain things. With short lengths it's not a problem. Overall I'm pleased with the effect and plan to use it in my own music. I hope you will too. As always I love when you let me know how you are using these plugins of infamy. Have fun, make music, be free. Here ya go: https://github.com/ssj71/infamousPlugins/releases/tag/v0.3.0 Enjoy! _Spencer
