CURRENT DOWNLOADPublished R1 build
Debian Core
For compatible x86-64 machines. The published R1 ISO uses an immutable system design with A/B updates and a dedicated recovery slot.
Your music. Your hardware.
Use a compatible computer you already have today, or follow our work on a purpose-built Brimstone appliance. Core is your music server; Control is the way you interact with it.
EXISTING MACSSigned QA; not notarised
macOS Core
One Core architecture spanning supported Intel and Apple Silicon Macs — a new purpose for machines that still have plenty to give.
FUTURE HARDWAREIn engineering
Buildroot appliance
Custom Brimstone system software and electronics developed with Howard Electronics: designed for longevity, modular updates and purposeful audio hardware.
DEBIAN CORE OS
Three boot slots.
One less thing to worry about.
A protected A/B system layout gives Core a path for safer updates. A separate recovery environment supports repair and rollback without making every music listener a Linux administrator.
Disk requirements, installation behaviour and recovery procedures depend on the released image; always consult the exact installer guidance before erasing a drive.
WHY WE BUILD THIS WAY
Keep using what you own.
The environmental case isn't a marketing calculation. It's a simple choice: a capable computer or excellent loudspeaker shouldn't be abandoned because its original software got old.
Less avoidable waste
Core for suitable older Macs and PCs can extend their useful service life. Hardware compatibility matters more than a new purchase.

Keep Meridian DSP speakers, Sooloos equipment and compatible endpoints useful alongside modern music libraries.
