- Oxbow: larger two-line control names and values, with the artwork raised to make room. (Hundekraft, based on zvenson’s OberVave)
- C64 arpeggiator: turn orange right to hold notes, like the stock arpeggio; Gate moves to Shift + orange. Turn blue left past Major for TABLE OFF, which plays only the keys you hold. (Hundekraft)

Getting started
From the project's README ("hundekraft 3.0.3 — OP-1 Firmware Workshop"):
Build your own Hundekraft 3.0.3 firmware for the original OP-1 at the workshop.
A firmware configurator for the original Teenage Engineering OP-1. Supply the original R246 update, select synths, effects and tools, and build firmware locally in the browser. The kennel core loads individual plugin files; every build supports 300 user synth presets. The current collection contains 152 presets, filtered to each build's synths and active effects.
Current 3.0.3 includes native kennel ports of op1r features through version 40: Randomiser, sampler+, Aether and the latest DSP, editor and monitor refinements. The manual and workshop cards use current kennel emulator captures for those additions; unchanged pages can retain older captures.
A normal update does not require Format drive. Factory reset clears user data; imported plugin files can survive it and a normal install. Connect the OP-1 and open Your plugins to review and remove an unwanted import. Back up before destructive recovery. …
