CHROMA – Grand Piano

CHROMA is Sonuscore's flagship piano virtual instrument, built on multi-sampled recordings from a Yamaha C3 grand piano captured across 23 velocity layers and 8 round-robin variations for mechanical sounds. The sampling approach prioritizes authenticity in sustain character and key release behavior, establishing it as a credible option for orchestral and scoring contexts where piano realism matters.

Beyond standard keystrokes, CHROMA includes extended techniques: palm mutes, brushes, mallets, e-bow, and chains. These articulations expand the instrument's palette beyond traditional classical repertoire, making it suitable for contemporary composition and experimental work. The core engine balances acoustic modeling with malleable sound design, allowing users to drift from literal recreation toward abstract textures.

Four freely adjustable microphone positions - including A/B, X/Y, ORTF, and submic channels - provide mixing flexibility and spatial control rarely found in competitive piano libraries. This architecture enables everything from intimate close-mics to distant hall perspectives. Attack, decay, delay, density, octavation, and sample-start parameters offer genuine sound shaping rather than cosmetic adjustment.

The velocity curve adjustment addresses a critical practical need: matching piano responsiveness to different controller keyboards, which vary considerably in feel and dynamic sensitivity. This feature alone justifies CHROMA's place in active production workflows.

CHROMA occupies a middle ground between specialized concert grand instruments and lightweight general-purpose pianos. It's best suited for composers, film score producers, and sound designers who value both convincing orchestral deployments and sonic experimentation. The combination of fidelity, control, and extended articulations makes it a versatile reference piano for professional work.
