How to use MIDI automation to Calf Saturator and LittleFly ?

by Jonathan E. Brickman

I'm studying a distortion add to my multifaceted BNR, and I'd like a way to introduce distortion as an effect right before final compression. To do that I have to be able to turn it off and on via MIDI automation. What kinds of MIDI signals do I need to send to Calf Saturator and LittleFly, in order to turn them off and on on the fly? I'll probably be sending them via mididings unless I need to find a different method. -- Jonathan E. Brickman jeb(a)ponderworthy.com <mailto:jeb@ponderworthy.com>

[music] Old as the stone

by Jeanette C.

Hey hey, Old as the stone is a kind of early 80s/late 70s soundtrack or synth piece with acoustic drums. Think of John Carpenter and add a little more melody. :) https://youtu.be/tJp9v5diHR8 Direct OGG download: https://www.dropbox.com/s/uynr9fo0062ljpa/old_as_the_stone.ogg On the Linux side I used LinuxSampler with the great Salamander drumkit, plus Midish and Nama with the usual collection of LADSPA plugins to produce and record the song. In hardware I used only monophonic, analogue synths, which was a little taxing when it came to the brass, having to record six tracks for that alone. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c You should never try to change me I can be nobody else And I like the way I am <3 (Britney Spears)

Running Decent Sampler: segmentation fault

by Jeanette C.

Hey hey, I just installed DecentSampler for Linux, trying to use the standalone version. I'm running ArchLinux. Running the standalone program results in a segmentation fault. Trying gdb on it, gives me this warning about Juce: 0x00000000008208c8 in juce::ComponentBoundsConstrainer::setBoundsForComponent(juce::Component*, juce::Rectangle<int>, bool, bool, bool, bool) () Not being familiar with Juce and all intimacies, I wonder if someone here might suggest a cause or even better a solution. I just installed Juce version 6.1.2 . The DecentSampler version is 1.3.6 (just downloaded half an hour ago). Best wishes and thanks for any hints, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Give me a sign...

Desktop replacements for ROX applications

by Will Godfrey

For very many years I've been using the combination of OpenBox and ROX. This has provided a very lightweight and user-friendly interface. It's also a good fit for the Raspberry Pi, and users unfamiliar with Linux seem to take to it quickly. However... ROX filer itself is still fine after all this time, but ROX-Lib relies on Python-2, so all apps using it are now dead - as is the rox -users list :( I can get round most of the ones I use but the two I need are desktop replacements for are the Archiving program (which handles a laundry list of formats) and screen resolution manager (based on XrandR). The usual web searches don't seem to show up anything useful. Any suggestions appreciated. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

XUIDesigner v0.3 released

by Hermann Meyer

Goal Provide a easy to use GUI generator tool to create X11 UI's for LV2 plugins. Currently only libxputty is supported, but the generated GUI C file could be used probably with other widget tool-kits as well, just a wrapper file is needed to translate the generated file to the needs of a toolkit. Currently state XUiDesigner parse the ttl file from a selected plugin and generate the needed controller widgets. Supported been the usual lv2:port parameter and as well the new atom based LV2_PATCH__writable and LV2_PATCH__readable so as LV2_ATOM__Path. XUiDesigner use the environment variable LV2_PATH to scan for plugins when no path is given with the -p command-line parameter. So you could easily create a GUI for a existing plugin. A integrated Color chooser allow to create a Color theme for your GUI. The created GUI could be saved as UI-Bundle, which then could be build (just make) and installed (just make install) to replace or provide a new GUI for the plugin. You could as well create a LV2 plugin from scratch and save it as Full Plugin-Bundle to a selected location. The project settings window allow to setup the specs (like Author name, URI, Audio/Midi ports, etc.) for your plugin XUIDesigner save the bundle in a git repository format, contain a working LV2 plugin with all needed resources (ttl files, converted C files from used images, etc.) and build files to build, install and run the new generated plugin. All you need to do to finish your plug is to implement your DSP part. Control widgets could be created and moved/resized freely around in the top Window. A grid could be displayed and widgets could snap to grid (left, right, Center) to order them easily. Control widgets could be grouped in a frame or a tab box and then the complete group could be moved to the final position in the Window. Any control widget could be replaced with a other control widget, so for example a Toggle Button could be replaced with a ComboBox, or a Knob could be replaced with a slider, or . . You could set the range for a controller, and it's default value, You could create enums for a ComboBox, . . Most Control widgets could be replaced with images you could select from a included file browser. XUIDesigner have a test-mode as well, which will build and run the created GUI, and give some useful information out in the terminal. Currently supported widget types * Knob -> support horizontal framed png/svg * HSlider * VSlider * Button -> support png/svg/horizontal framed png/svg * Toggle Button -> support horizontal framed png/svg * ComboBox * Value Display * Label * VMeter * HMeter * Frame * TabBox * WaveView * File Chooser Button Build * git submodule init * git submodule update * make * sudo make install # will install into /usr/bin https://github.com/brummer10/XUiDesigner https://github.com/brummer10/XUiDesigner/releases/tag/v0.3 regards hermann

[Music] Uphill

by Jeanette C.

Hey hey, here's a new piece, an upbeat electro track, which is not exactly EDM: https://youtu.be/g6u2bsV7KfA direct OGG download: https://www.dropbox.com/s/7ttga6839e9k9ch/uphill.ogg This is the piece I first recorded for the Loopop Mega contest and then put aside for being too obvious. :) In Linux it was realised with LinuxSampler, thankfully all samples were provided as SFZ instruments. The piece has a very easy-going b-section and otherwise a colourful mix of different sounds from all sorts of different technology, digital to hybrid to analogue, desktop to keyboard to eurorack. I enjoy seeing such different sources playing so well together, growing into one monolythic arrangement.

New software instrument: handpan

by Jeanette C.

Hey hey, this is a physically modelled handpan, designed for live MIDI playing. It's written in Csound. http://juliencoder.de/sound/handpan-1.0.zip It's tested with Csound 6.16, but should work with 6.15, maybe even 6.14. As it comes it's configured for ALSA audio output and ALSA sequencer input. All choices for audio and MIDI I/O are listed at the top. Also you can create any equally tempered scale you like. There are two example scales in the file. Only one can ever be active. If you play notes on the keyboard that are no in the scale you will strike the resonator, i.e. any part of the instrument that isn't a clean note. This instrument has been roughly modelled on a Rav drum, which I had the pleasure to play, including the stereo spread of the notes. I hope someone finds a use for it.
