Easy Low-Pass Gate in PureData

by SimonPosted on No Comments

Building a simple low‑pass gate (LPG) in Pure Data Vanilla, combining filtering and an envelope for that “West-Coast”, organic, percussive sound.

In this no-talking, patch-from-scratch video, I create a basic LPG patch, showing how to combine a low‑pass filter with an envelope to emulate the behavior of classic analog LPGs used in modular synthesizers like the Buchla.

Low‑pass filters, unlike VCAs commonly used in “East-Coast” synthesis, change both the timbre and amplitude of a signal at the same time. Emulating this idea in our digital synths can be a cool way to create natural‑sounding plucks and percussive tones.

“Ancestor” Released on Music from SEAMUS, Vol. 35

by SimonPosted on No Comments

I’m pleased to share that my piece Ancestor for Apple Watch and Eurorack synthesizers has been released on “Music from SEAMUS, vol. 35”, a collection of works selected from the 2025 SEAMUS National Conference, now available through New Focus Recordings.


Ancestor is one of my series of ongoing creative projects that explore hybrid systems of both digital control and analog synthesis. In this piece, I send data from (digital) wearable technology (Apple Watch) through OSC to my Eurorack to control analog synthesis. The piece uses biometric and movement data coming from the watch, leveraging the benefits of digital control and the immediacy of analog synthesis.
