I’m created this VCO using Bela (bela.io) and following their C++ Real-Time Audio course. This is for lecture 6. I’m learning about this microcontroller which is attached to a BeegleBone computer. it’s as small as a microcontroller, amazing. It’s fun to learn about these tech tools. I’ve made instruments in the past using Arduino, Teensy, openFrameworks (C++), and MIDI. The Bela course is teaching me about optimizing real-time audio as their microcontroller is 10x times faster then MIDI…ideal for live performances. I’m taking the time to learn to see how I want to build my instrument… a lot of noise in this video, but I would like to create harmonious sounds… The potentiometers use a voltage divider to send voltage to Bela, which is mapped to frequency, amplitude and a detune algorithms. Fun stuff 🙂
Frequency and amplitude are visualized in the plotter. I used potentiometers, a FSR sensor and an eTextile bend sensor I made.
