Chroma Upright Piano vs Una Corda

The fundamental difference between these two upright piano VSTs lies in their core sound sources and the resulting sonic characteristics they offer. Sonuscore's Chroma Upright Piano samples a Wilhelm Diemer instrument, while Native Instruments' Una Corda uniquely samples a custom Klavins piano where each key has only one string instead of the typical three.

This single-string design of the Una Corda leads to a characteristically pure, resonant, and often experimental sound, reflected in its smaller 10 GB library and single microphone position. In contrast, the Chroma Upright Piano leverages 27 velocity layers, 4 mic positions, and a larger 17 GB library to deliver a warm, intimate, and natural timbre, further enhancing its versatility with unique articulations like felt, muted, plucked, and bowed sounds that are absent in Una Corda.

Choose Chroma Upright Piano if you require a highly dynamic and versatile upright with diverse articulations suitable for recording and film scoring. Choose Una Corda if you seek a distinct, pure, and atmospheric sound for experimental textures or specific cinematic and jazz applications.
