PianoRT is a purpose-built Linux appliance for Pianoteq. Not a general-purpose PC. A single-purpose instrument that boots in seconds and gets out of your way.
Custom-compiled real-time Linux kernel. Scheduler tuned to prioritize audio threads above everything else on the system.
Proprietary firmware is a source of unpredictable interrupt latency. Replaced with coreboot โ open, minimal, and reproducible.
Low-latency JACK operation via PipeWire. Bluetooth and WiFi disabled on production units to eliminate interrupt storms.
Unnecessary services stripped. Boots directly into Pianoteq โ no login, no distraction.
The sweet spot. Handles dense Pianoteq patches with headroom. PREEMPT_RT fully dialed.
Pricing and full specs on the Certified Systems page.
PianoRT is built entirely on open-source software. Each component can be inspected, reproduced, or improved. The full build process is documented on GitHub.
Foundation of the stack. PREEMPT_RT patch applied for deterministic, bounded scheduling of audio threads.
Open firmware replacing the proprietary BIOS. Reproducible, minimal, faster to POST.
The real-time patch set for Linux. Converts the scheduler into a fully preemptible system.
Next-generation audio server. JACK-compatible low-latency operation with modern session management.
The physical modeling piano software these appliances are built around. Modartt's instrument engine.
UEFI firmware implementation used as the coreboot payload for full UEFI boot compatibility.
