Ed Kelly’s “Islands 2” Pd Patch
Exploring the intersection between code and music
I’ve been working on implementing a Kalman filter for Pd. This is a very simple 1-dimensional version that works nicely for cleaning up sensor data.

My song “Terms of Venery” for baritone and piano, sung by the late great Wes Brax. Drew Dolan on marimba and spoken voice.
HARMONICITY
The inspiration for this code came from a passage I read for a class on Renaissance music last week:
“The Pythagorean tradition that persisted throughout the Middle Ages and early Renaissance defined consonance in numerical terms. The intervals that were products of string-length ratios expressible by the number one to four were consonances; the rest were dissonances.” - Claude Palisca, “An Italian Renaissance in Music?”
