portrait of tracy mcgrady — upcoming EP
tracy mcgrady’s 13 points in 35 seconds, reborn as motion and melody. the eruption translated into arpeggiated synth and harmonic tension, seasoned by the influence of jaco pastorius’ portrait of tracy.

lambrOS upgrades: tightening reproducibility proofs and now using BLAKE2b. Ultimately, lambrOS now operates like a PRF, but with output that needs to be both deterministic and aurally pleasant, and the ciphertext is MIDI.

This makes it frustrating to have a productive discussion about election security. There's no simple narrative. Yes, there are security vulnerabilities in some election systems, and that's genuinely bad. But no, there's no evidence any US elections have been stolen or rigged this way (so far).

As lambrOS evolves, I'm applying a lot of rigor around the consistency and fidelity of how it produces MIDI from real-world signals. The first step was reproducibility; even with multiple dials for introducing entropy, it's imperative that any output can be reproduced with fixed parameters. (1/1)

New lambrOS feature: YAML now has toggles for printing chord voicings, musical notation, and tabs. One future goal is to have a post-production feature that scans output for legal-but-jarring chord voicing, and can auto-polish ("rounding up/down") or present the user with alternatives.

It's basically reimagining cryptography's indistinguishability for music: provable pseudorandomness within a tonal space. A series of entropy dials, when fixed, ensure this; when dynamic, they leak the MIDI's aesthetic policies, which makes for a neat "harmonalytical" problem.
Starting in 2026, I’ll release a suite of field ciphers that feed ciphertext directly into lambrOS, a system built from cryptographic design, probability theory, and music theory.
It turns structured data into harmonic motion and probabilistic musical form. (1/6)

You could also frame lambrOS as a musical version of cryptography's PRF, where you have absolute control over consonance and dissonance in a provable way. Although not the primary goal of lambrOS, you *could* use this as a MAC that's playable as music. digisigs.mp3 ftw.
Here’s a bit about “shapeshift,” a chord-shaping component of lambrOS, a musical engine for turning real-world signals into musical structure; it’s built around concepts from cryptographic design, probability theory, and music theory. (1/7)

lambrOS '26 will now have microtonal support because Maddie Ashman boggles the mind and bends the ears so brilliantly.

After watching South2 West8’s Tenkara Session, I couldn’t stop thinking: What if the ritual of fishing, from cast → drift → bite → hook set → fight → release, could be translated directly into music? (tenkara = a type of simple rod angling traditionally practiced in Japan) (1/8; music at 8/8)

Also working on [codenamed] lambrOS, which is a more expansive engine that collapses midrangeOS' functionality into a plug-and-play adaptor; this allows for custom, swappable adaptors that handle input according to entirely different rulesets, such that nothing is hardcoded into the primary system.
Here's a synthy snippet of raw MIDI that works like this: midrangeOS took in data from T-Mac’s 13 points in the final 35 seconds of the Rockets vs. Spurs game on 12/9/04. Every play — pass, shot, rebound — is assigned a weighted numerical value. (1/4)

This is amazing information warfare. Exact parallel to Bletchley Park breaking the Enigma machine.
