    Control Your DAW with this Rock-Solid Roland Sequencer

    DAWless-style workflow without giving up the power of the DAW. The Roland MC-500mkII (1988) — the kind of beautiful, tactile box you can run without looking — drives your DAW's transport, jog wheel, and 99 location memories. A small bridge does the connecting.

    Two AIs, One Feature: What Happens When Claude and Codex Build the Same Thing

    Claude Code and Codex independently implemented the same draggable zone feature for the Akai S3000XL editor. The code was comparable. The sessions were not.

    What Happened When We Asked Claude and Codex to Build the Same Feature

    We asked two AI coding agents to implement the same draggable zone editing feature for the Akai S3000XL editor. The most useful comparison wasn't about code quality -- it was about failure modes.

    Reverse-Engineering the Akai S3000XL MIDI-over-SCSI Protocol: An Odyssey

    How a failed attempt to run Akai's MESA II in a Mac OS 9 emulator led us through 38 disproven theories in five days of intense debugging, and ultimately to a standalone 68k emulator that cracked the protocol in four hours.
