Amplitude Problem is Juan Irming, a Los Angeles producer, composer, sound designer and keyboardist with a focus on synthwave, chiptune, soundtracks, hip hop, video game music and sound effects.

Juan got his start on the European demoscene in the late 80s as the composer for world-famous and humble Atari ST demo crew SYNC, placing first in several demo music contests. Since attending Musicians Institute in the early 90s, he has composed and produced video game inspired synth and chip soundtracks for a number of projects and records such as legendary geek rapper YTCracker's cyberpunk album Introducing Neals. Credited on 11 LPs, he has been featured on albums alongside artists like Mitch Murder, Lazerhawk and GUNSHIP. Juan has appeared live at events and venues such as Comic Con and Game On Expo alongside acts like The Gothsicles, The Minibosses and Future Holotape. He also writes themes for video games such as Power Drive 2000.

Influences include first-generation chip composers Rob Hubbard, Ben Daglish, Martin Galway and Maniacs of Noise in addition to electronic, industrial, jazz and hip hop acts such as Damokles, Kraftwerk, Jean-Michel Jarre, Alphaville, Depeche Mode, Nine Inch Nails, Herbie Hancock and Public Enemy.

I'm into Just Intonation (JI), which is using harmonics (or undertones) to generate music. Over time, my profile will fill up with wonderful and melodious New Harmony, fresh from the infinite vaults of the original and best source of harmony, Just Intonation.

I’ve written some papers on the music theory of Just Intonation. You can check them out via the arXiv link below. Topics include the mathematical analysis of harmony (in Just Intonation), and a notation system to cover all of Just Intonation.

Enjoy listening!
