01. ACOUSTIC ENGINEERING

Surgical sound design, effortless mix fit

Dynamic Velocity Curve

Smooth, non-linear velocity curve modeled after acoustic hammer escapement. Responsive from delicate, whispered pianissimo to striking fortissimos that cut through 808s and heavy drum grooves.

Felt Warmth Acoustic Filter

Tired of harsh high-frequency clatter? Our dedicated Warmth circuit attenuates abrasive hammer transients while enriching mid-body fundamentals, instantly dialing in that moody, cinematic felt piano timbre.

Stereo Impulse Hall Reverb

Convolution-modeled concert hall space tailored specifically for piano acoustics. The dry signal remains locked at unity gain, guaranteeing the piano never loses punch or body as you add spatial depth.

Zero-Bloat C++ Engine

Native C++ architecture built with JUCE and lightweight Decent Sampler framework. Stack 20 instances across your project with near-zero CPU load and load your DAW sessions in under two seconds.

Mono-Safe Phase Coherence

Auditioned across phone speakers and club sound systems. Phase-aligned microphone imaging ensures your chords stay punchy and present in mono summing without catastrophic comb filtering.

Full 88-Key Expressive Span

From thunderous subsonic bass notes on C0 to crystalline, glassy bell tones at C8. Full octave shifting and comprehensive MIDI CC64 sustain pedal modeling included.
