Re:Polyend releases the Tracker firmware source code on Tuesday November 03, 2026 @06:33AM (#50350696)
I have been doing firmware hacking of audio devices as a hobby for the last 20 years. I released a CFW for Volca Sample almost a decade ago that was fairly well received, but have also hacked other Volcas, Zoom multitrackers, Line6 fx, Variax guitar, Digitech looper, couple Reface, AKAI, Stylobeat etc. I have some observations:

1. I tried running ghidra from claude about a year ago. I was not impressed, it was not really that good. It felt confused and not knowledgeable enough. I picked it up again a couple of weeks ago, and must say - it is nothing less than spectacular. I am having a small existential crisis here, Terry Tao light. 100x my skill, 1000x my speed it feels like.

2. Like all consumer products, design and brand is essential to the buyer/user experience of audio tools. Removing options in UX is what design entails a lot of the time. You are in reality paying a premium for options to be deleted from menus, gently nudging you into a curated brand culture. Acting like it is inherently bad is missing the point. It is like insisting everybody should roll their own Arch Linux on their laptops.

3. Audio tools/synths/fx/sequencers/controllers are instruments. The value of an instrument is to a great extent dependent on the time invested in learning it, as opposed to inherent things like "audio quality". Music is very in-the-moment, so any cognitive friction that takes you out of the flow is gonna detract from the experience. Having a "fixed" UX is in this sense a way of focusing, honing muscle memory and releasing flow. Watch Jeff Mills hunched over a 909, that is some Paganini shit. Standardization drives adoption, adoption fuels cultural expression, expression creates genres.

From an individual tech-loving buyers' point of view, the AI revolution in CFW is fantastic, from the vendors point of view, not that easy to handle.

Hey thanks for the shoutout! I loved your article here, it is a wonderful intro to this kind of work. I started the Volca RE work on IDAPro, but moved over to Ghidra later...
