Sonoj Convention 2019 - Announcement #1 - Looking for Speakers (no papers required)

by Sonoj Convention

Ladies and Gentlemen, The Sonoj Convention is an annual event in Cologne, Germany about music production with free and open source software (and hardware). This year it will be on October the 26th and 27th 2019. It features demonstrations, talks and hands-on workshops. Meet like-minded people, learn insider knowledge and tricks, participate in our one-hour production challenge! Everybody is welcome, no matter your musical or technological background or capabilities. Our Website: https://sonoj.org This is our first announcement, reaching out to our core audience. The event is more than half a year away, but we are starting talks to find speakers and lecturers now. Sonoj is not a software-developers conference; instead the stereotypical speaker is an experienced musician or producer. If you would like to make a contribution, please send an informal and short e-mail with your ideas to info(a)sonoj.org Here are some examples from the past years, to get an idea: * Creating a Radio Drama with Ardour (for Beginners) * Synthesizing electronic dance music with ZynAddSubFx * Carla Plugin Host Feature Demonstration and Workflows */Making Music with Text/ - Audible Programming with Sonic Pi /* The Realm of Too Many Options/ - Write, record, mix and actually finish your music. * Fantasy Game Soundtrack Production in an open source ecosystem If you would like to participate creatively in the Sonoj Convention please reach out to us! (And if you just want to visit, the visitor registration is already online as well) I am looking forward to your answer! Nils Hilbricht Sonoj Convention https://www.sonoj.org.

Command-line render a MIDI file with a VST instrument?

by Mark Raynsford

Hello! I'm attempting to produce a set of sound files that will be loaded into a sampler. Given a MIDI file that contains a single channel containing eight one-second notes, I'd like to be able to instantiate a VST plugin, load a preset into it, pass the MIDI file through it, and record the output to an audio file without any leading or trailing silence. I'd like to be able to do that entirely from the command line without any interactivity. I have a couple of hundred repetitions of this that I'd want to perform, so as you can imagine I don't want to waste any time on manual input. Is there anything open-source out there that allows for this kind of headless, command-line rendering? -- Mark Raynsford | http://www.io7m.com

by olaf＠klingt.org

Hey I got my hands on the sound devices usb pre 2. It works well in 48k out of the box. Because it should be also standard compliant for usb2 which would make it possible to work in 96k I wonder what would have to be done to make this possible. Where should i ask this question? best, olaf

Purr Data participation in GSoC 2019

by Jonathan Wilkes

Hello Linux audio, I am the maintainer of Purr Data, a fork of Pd that focuses on usability and ships with lots of external libraries. We're doing our second year of Google Summer of Code, and I'd like to put a call out for anyone here who is in college to apply to be a student with our organization this year. Our GSoC organization page is here: https://summerofcode.withgoogle.com/organizations/5078817117306880/ There are opportunities to work on code in C, C++, Javascript, Lua, Python, and probably any other language that can interface with C. If you use Pd please keep in mind the possibility of doing a project by writing in Pd itself. Pd is a programming language, and it's possible to use it to write fully-functioning libraries for both DSP and general purposes. So if you've ever written or performed using Pd, do consider the possibility of participating in GSoC this year with us. Best, Jonathan
