My installation project will have two interactive elements: ultrasonic sensors and a theremin-like natural plant; these two elements will be controlled by the DSP programming language Pure Data. There will be also two screens showcasing reactive 3d imagery and this images will also be generated by Pure Data with an especial library called Gem. To control the sensors I will use the hardware extension Bela Board, and to achieve the sensory plant I will use a device called Biotron, I will speak a bit more about these in further research.
The sound that these interactive elements will play will be created from scratch in Pure Data, and I want to develop my own sound sources for them. In this case I’ve built a polyphonic synth voice that could establish the foundations of the sound that I want to achieve, it features 8 sine wave oscillators with a slight detune on each of them to make it sound harmonic and 8 sawtooth waves with the same characteristics, they’re also processed with a reverb object. These sounds will be controlled via MIDI with the special hardware but I think that is best to try them first with a traditional MIDI controller and I have been jamming with it and recorded it in this video so we can hear and see the results of this first steps on the sound design of the installation.
