DECAURA/DECADENCIA

Purpose

Installation for Mostra Sonora i Audiovisual - Convent de Sant Agusti, 2023 - Barcelona.

By Rebecca Anne Peters and Óscar González.

Usage

1. Launch sonic-pi on a raspberry pi with startsp.sh. This is for using sonic-pi without a screen.

2. Use sonic-pi-tool (forked from emlyn to interact with sonic-pi server from the command line. You can run a composition with sonic-pi-tool.py run-file <composition>

3. Install python requirements (python 3 only).

4. We use this adafruit DAC with a Pi-zero. With this we output to a speaker. We also use one GPIO (17) from the pi to control some lights with relays - this control is done with osc messages from sonic-pi that are listened by async.py. Modify SERVER_IP, SERVER_PORTand UDP_FILTER accordingly to listen to your osc messages.

5. controller.py is a simple random player using calls to sonic-pi-tool. It also checks everything is fine on the server side at boot. We use it with a cronjob @reboot, alongside startsp.sh to spin a server without a screen on a pi zero

That's it!
