I also made a plugin playground codedmachines.com/playground…. See the `filtre` and `french touch` plugins. Eventually, I'll release the emulator, but it's still rough.

The Lua plugins are pretty crazy! I pointed Claude at a few 100$+ plugins online, and it was all able to recreate them in <1h. What a time to be alive 😄

One the frustrating parts of working with hardware is the number things gated by groups charging ridiculous amounts. Today’s example: you need to become a member of the USB forum to get a vendor ID: usb.org/getting-vendor-id. Cost? 6k/yr!!

Some nasty 808 made from scratch (from oscillators + FX) on the device this week: codedmachines.com/log/2026/0…. And, I discovered Memory LCDs. Oh my!! It's like eink but with a decent frame rate. Ordered a bigger one w/ frontlights 😎

Got tired of using herdr on my phone, so I built an eink device for it. So much nicer to read! Pink button is push-to-talk. I think I might not need a laptop anymore 😂

Built my first hardware instrument in 3 days last week. It's Orbit — a 4-track stereo looper with tempo-locked everything, live effects, and a screen that animates with the sound. 🧵

Already deep into V2: bigger/sharper screen, a real enclosure, better knobs and buttons, more tracks... Follow along on macournoyer.com/looper or here. And, LMK what you think!
