Modular synth artist

Slow electronic music from a small modular synth

I'm Hiroko. I make long, slow pieces on a modular synth in Kyoto, with water and bells recorded on my walks, and I teach how to patch one from the first cable.

  • One oscillator, tuned by ear
  • Splitting a signal in two

A first patch, cable by cable

The patch every lesson builds: a clock, one oscillator, then a drone and a rhythm from the same sound.

Patch lessons

About

Hello, I’m Hiroko

I worked as a sound engineer in Osaka for twenty years before I bought my first six modules. Now I live in Kyoto, play small rooms and galleries, and release a long recording every season.

My lessons follow one patch from a single clock to a recorded take. I keep the case small on purpose: six modules are enough for a lifetime of music, and most of mine are about listening, not buying.
