Bitraf is in cooperation with Notam holding a workshop where the participants will build their own digital processing box COSMO, or Csound On Stage Music Operator. This happens at Bitraf in Pløens gate 3 in Oslo on the 29th and 30th of October, 10am-6pm.

Csound is a powerful, multi-platform, real-time sound-processing environment that enables musicians to design their own instruments and audio-effects by writing a few lines of Csound code. The aim of the “Csound On Stage Music Operator” (COSMO) project was to embed Csound into a stand-alone musical device especially designed for live performance. An advantage of such a embedded design is the straightforward inclusion of individual designed digital audio-effects into a regular live-electronics setup and provide direct haptic control of Csound to the performing musician. Such a musical device may also enable non-programming instrumentalists to include Csound in their analog live-performance setups.

The base design allows for 9V powering, regular quarter jack-in and jack-outputs for sound, MIDI in/ out (via USB), up to 8 analoge controller inputs (pot meter, expression pedal jack or other sesnsors) and 8 digital controller in/outs (switches and leds). Csound 6 (Csound Python API) is running on a Raspberry Pi microcomputer, equipped with an additional sound card for low?latency audio input and audio output and a custom designed PCB board COSMO Cross Mixer that provides relay based true?bypass and a stereo dry/wet mixer circuit. Everything will be mounted into either a sturdy aluminum box or a elegant wooden box. Both boxes will provide access to the USB and Ethernet ports on the Raspberry Pi for easy access to loading in new Csound files and connecting additional devices. The workshop contenders will make their own design based on the available choices (type and amount of controllers and their physical layout) and then proceed to building their very own COSMO box by soldering and mounting the different components. All necessary components will be brought by the workshop holders and are included in the workshop fee.

COSMO Aluminium Box: 2350 NOK

COSMO Aluminium Box – Synth version (no audio input): 2050 NOK
