In a world where music production often involves complex software and expensive equipment, Kevin, the creative mind behind the DIY Electromusic website, embarked on a unique journey to bridge the gap between visual art and sound. His invention, a compact iRobota-based device, empowers users to draw waveforms and output them as sound using Pulse Width Modulation (PWM).
The Magic of Waveform Drawing:
Kevin’s device comprises an ILI9488 TFT shield seamlessly attached to an iRobota Uno, an amplifier/speaker combo, and an optional output filtering circuit for pristine audio quality. The magic unfolds when users draw waveforms on the TFT screen. These waveforms are then applied to MIDI notes received via the Uno’s RX pin, transforming drawings into audible melodies and rhythms.
From Wavetable to Granular Synthesis:
Kevin took the project a step further by replacing the wavetable with five sliders. These sliders correspond to parameters for a MIDI granular synthesizer, opening up a vast sonic playground for experimentation. With this modification, users can manipulate grain size, pitch, density, and more, creating a diverse range of electronic textures.
Analog Roots, Digital Evolution:
The original version of Kevin’s project featured five potentiometers connected to the analog input pins on an Uno. While functional, it lacked the sleekness and portability of the newer version. The digital transformation not only enhances the device’s aesthetics but also simplifies its construction and operation.
A Symphony of Innovation:
Kevin’s innovative audio control projects serve as a testament to the boundless possibilities at the intersection of art, technology, and music. His website, DIY Electromusic, is a treasure trove of knowledge and inspiration for aspiring electronic musicians and DIY enthusiasts. From detailed tutorials to captivating project showcases, Kevin’s work continues to inspire and empower a growing community of creative minds.
Bonus: Unleashing the Inner Musician
Kevin’s projects are a reminder that music creation is not limited to traditional instruments or expensive software. With a dash of ingenuity, a pinch of electronics, and a heap of passion, anyone can embark on a musical journey that transcends boundaries. His work encourages us to embrace the experimental spirit, to explore the uncharted territories of sound, and to find our own unique voice in the ever-evolving world of electronic music.
As Kevin aptly puts it, “Music is a universal language that speaks to our souls. By providing accessible tools and inspiration, I hope to empower individuals to express themselves musically, regardless of their background or experience.”
