When a HPF Causes Clipping (Filtering, Phase, & Constructive Interference)

How can a low-pass filter increase amplitude even though filters remove frequencies?

In this video, I explain how *phase shifts* introduced by your filters can cause constructive interference, increasing amplitude and even leading to clipping. We’ll explore:
-Why filtering can boost amplitude
-How phase changes affect waveform shape
-Strategies for filtering in synthesis and mixing

Understanding this concept can up the game of sound designers, mixing engineers, and anyone working with EQ or synthesis.

The Three-Oscillator Problem: Chaos and Emergence

Simple rules to sonic chaos: the “three-oscillator problem” & Rob Hordijk’s “Benjolin”

In this video, I talk about the “Three-Body Problem” and created an analogous Pure Data patch, where three oscillators frequency-modulate each other. Just as in the physics problem, this cross-modulation network creates unpredictable, chaotic patterns.

This emergent complexity from simple rules perhaps connects to ideas of motivic development in music, how great artistic works can grown from simple and small ideas.

Feedback Loops & Acid House (“Hum” live set)

“Hum”: Acid house meets analog chaos, live feedback loops performance

This is my live performance set “Hum”, blending digitally controlled analog synthesizers, surrealist acid house grooves, and feedback textures. Recorded in my home studio, this video revisits the set I played live at Synth-tember / Mini-Blorp at New Alliance Gallery in Somerville, MA.

Featuring chaotic 303 basslines (from Herbs & Stones Liquid Foam), evolving feedback loops (from the Random*Source Serge Resonant EQ), and hybrid digital/analog sound design, this should satisfy fans of modular synth performance, experimental electronic music, and custom audio setups.

Sequencing an Alesis D4 Drum Module with Arturia DrumBrute Impact

Sequencing a vintage Alesis D4 drum module with an Arturia DrumBrute Impact for classic 90s electronic percussion sounds.

Today, I’m connecting my Arturia DrumBrute Impact to a classic (?) Alesis D4 drum module through a MioXL interface. I explain the very straighforward setup, then check out the retro drum sounds of the D4 while sequencing from the contemporary DrumBrute Impact.

Why is this cool? These two pieces of hardware made decades apart still communicate perfectly thanks to the enduing MIDI standard. It’s a reminder of the expressive possibilities of “obsolete” technology and how vintage gear can still inspire new creative workflows.

Japanese Famicom Controller 2 Microphone

Retro console teardown meets audio hacking: turning classic hardware into sonic experiments.

Have you ever wondered what’s inside a Japanese Famicom? Well I did. Particularly what that microphone in controller 2 is like. Luckily, last summer when I was in Japan, I found a “junk” Famicom console for under $6 and, in this video, I break it down to check out what’s going on inside. I open up the controllers and the main system, extract the microphone, and wire it into a custom circuit to hear what it sounds like.

This is part teardown, part audio experiment, and completely perfect for fans of retro tech, DIY audio, and creative sound design.

Pd Envelope Follower Patch from Scratch

In this no-talking, step-by-step video, I build an envelope follower patch from scratch using Pure Data Vanilla.

I route the amplitude of an incoming drum beat to control various parameters of a sawtooth oscillator ([phasor~]) in real time:

🔹 First, the amplitude of the sawtooth wave follows the drum signal.

🔹 Next, the oscillator frequency responds dynamically to the drum’s envelope.

🔹 Next, I patch the drum’s amplitude to modulate the cutoff frequency of a filter.

🔹 Finally, I make an old-school envelope filter by applying the envelope-following filter to its own input.

This is a hands-on demo for anyone interested in interactive audio, modulation techniques, or learning how to build dynamic control structures in Pd. All done in Pure Data Vanilla, from scratch, with no external libraries. Perfect for beginners exploring envelope followers or anyone wanting to see modular ideas implemented visually.

AI, Retro, and Music of Our Time

As musicians, how should we respond to the rise of AI in music? In this video, based on an article I wrote for the SEAMUS Journal, I explore the cultural, ethical, and artistic implications of generative AI tools. Rather than framing AI as a threat or miracle, I argue that it’s a technology we must actively engage with, both critically and creatively.

Rather than surrendering to nostalgia or automation, artists can explore how to engage AI as a tool for meaningful, speculative, and human expression.

Embrace the Random (Algorithmic Synthesis Nuances)

Composing small elements of randomness into your synths to add nuance, movement and human feel.

In this video, I “embrace the random” and show some ideas for adding dimension to your synths by passing off some parameters to randomness, exploring how introducing small elements of randomness to a synth in Native Instruments Reaktor. These kinds of details help synths feel less rigid and more expressive, especially when looping or playing repetitive patterns.

I made an analog saturation box for $2, and here’s how it sounds (diode clipping)

Can you build a stereo analog distortion box for just $2? Yes, you can! What does it sound like? Well, you’ll need to watch the video for that.


In this video, I put together a simple passive DIY distortion circuit using just 4 diodes, 4 wires, and 4 audio jacks—all dirt cheap but surprisingly effective. This little box works by clipping taking advantage of the diodes’ forward voltage to clip the signal, a classic analog distortion method found in everything from guitar pedals to vintage studio gear. It’s cheap, it’s basic, but listen and see if this might add that grit and warmth that you’re looking for (and, if not, you’d only be out $2).

* 4x Diodes (1N4148)
* 4x 3.5mm Audio Jacks
