Code

C++

• The Half-Physler as presented at NIME 2019 [1] and the resontube opcode as presented at the ICSC 2019 [2]

  • In this repository you find the C++ code to compile the tube models [3] as opcodes for Csound. The opcodes are implemented following the guidelines of the Csound Plugin Opcode Framework [4].
  • https://github.com/ketchupok/half-physler

Csound

• The COSMO DSP library contains +20 Csound-based audio effects (DSP-Library/Effects).
  • https://github.com/cosmoproject/cosmo-dsp
  • Find a detailed manual and introduction here.
  • Code by Alex Hofmann, Bernt Isak Wærstad, Kristoffer Koch, Kim Ervik, Iain McCurdy, and others. (2013–2019)

Supercollider

• CCIn - CC-Responder MIDI-In wrapper for SuperCollider
  • https://github.com/supercollider-quarks/CCIn
  • This class makes it quick to send MIDI control values to UGen arguments. It initialises a CCResponder and maps the received data onto control busses. Those can be read out by the class itself.
  • Code by Alex Hofmann & Florian Golz, with support from Fredrik Olofsson & Alberto DeCampo (Dez. 2010)

Install within SC-Lang:

Quarks.install(“CCIn”)

Then choose: “Language-> Recompile Class Library”

Usage:

// simple example
m = CCIn.new;      // listen to all midi in ports and all midichannels
x = {SinOsc.ar(m.kr(0, 0, \freq), 0, 0.2)}.play  // MIDI Chan = 0, CC = 0, Range 20-20000 Hz
m.free;     // loosing control
x.free;     // free synth

Music

• SuperCollider code for “Tight-interlocked Oscillators”

Python

• Developed within the ASEA-Uninet project on distributed ethnomusicology data, this is the code base for a proof-of-concept implementation for an API-service for Music Information Retrieval, running in parallel with a Data Repository (Dataverse). Authors and details in [5], including an example analysis, based on the model by [6].
