Workshop – bygg din egen digitale effektpedal

BEK 12.11.2016 10.0013.11.2016 18.00



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 standalone musical device especially designed for live performance.

An advantage of such an 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 analog controller inputs (pot meter, expression pedal jack or other sensors) and 8 digital controller in/outs (switches and LEDs). Csound 6 (Csound Python API) is running on a Raspberry Pi micro- computer, 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 aluminium 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.

Participants will make their own design based on the available choices (type and amount of controllers and their physical layout) and then proceed to build their very own COSMO box by soldering and mounting the different components.
