Philosophy
Software that
respects the
instrument
MIDI tools designed by a keyboard player who got tired of bloated software that never quite understood what a live performance actually requires.
Built for Real Workflows
Every feature comes from actual musician frustration. If a problem exists on stage or in the studio, it gets solved — not worked around.
Precision Over Bloat
Tools that do exactly what they say. No feature creep. No subscription. No telemetry. Software that respects your time and your signal chain.
Performance-First Architecture
Low latency, zero dropouts. Every tool is designed to handle the demands of live performance — not just studio sessions.
Open & Transparent
Source code on GitHub. Documentation that actually explains what's happening. Built by a musician who trusts other musicians.

About
Built by a
musician
who codes
Ernest Keyz Studios is an independent music software company built around one core belief: the best tools come from people who actually use them.
Every product starts with a real problem — a missing diagnostic during a live set, a MIDI routing quirk that took hours to debug, a workflow that should have taken one click but took twelve.
The studio sits at the intersection of music performance and software engineering. That's not a background that's common in music tech — and that's exactly the point.
