qtamp ~ qtWasabi Reference Player


I never wanted a player that looks like Winamp. I wanted one that actually runs Winamp skins. The difference is bigger than it sounds. A Modern Skin is not a bitmap theme, it is a program. XML declares the widget tree, compiled Maki bytecode drives the behavior. Drawers slide, tabs switch, windows change their shape, all of it scripted by the skin itself. Repaint that and you have a pretty poster. I wanted the original.

That is why qtamp runs skins as real programs. qtamp is my Qt6-native music player and the reference player for qtWasabi, my independent reimplementation of a Modern Skin engine. Skins ship their compiled Maki bytecode with them, and qtWasabi executes it in its own Maki VM. The skin’s logic drives the interface exactly the way it did in 2002.

The name is a play on words. “Qt” as in the framework, “qt” as in cute. A Qt-native amp, and hopefully a cute one.

Gigboy ~ Songbook & Gig-prep App


Gigboy is a web app for musicians and bands to write, organize, and rehearse songs from — built on the open ChordPro format, so nothing you write is ever locked into a proprietary format or someone else’s server. It’s self-hosted only: you run it on your own machine, NAS, or VPS with one Docker Compose command, and your band’s setlists, recordings, and press kit live in your own database, not a startup’s.

No subscriptions, no per-seat pricing, no feature paywalls — every account gets full access.

k-synth ~ Pocket Calculator Synthesizer


/synth is a minimalist, array-oriented synthesis environment. Heavily inspired by the K/Simple lineage and the work of Arthur Whitney, it treats sound not as a stream, but as a holistic mathematical vector.

📐 The Philosophy

This isn’t a DAW; it’s a vector-processing engine designed for “Base Camp” signal processing.

It uses:

  • One-Letter Variables: A-Z globals only.
  • Right-Associativity: Expressions evaluate from right to left.
  • Vectorized Verbs: Math applied to entire buffers at once.

Sound is a vector. A kick drum is a vector. A two-second bell tone is a vector. You do math on vectors and the result is audio. There are no tracks, no timelines, no patch cables — only expressions.
