GBR Loops has released Harmonium Scale Changer for Kontakt.
GBR precisely sampled many layers of a carefully chosen harmonium with a Neumann U87, including Key Noise On/Off Hard Press On/Off Bellow sound, etc. All sounds can be separately controlled in Key Control mode. Additional features are ADSR, Reverb, Chord Mode, and Transpose.
Requires full version of Native Instruments Kontakt 5.6.5 (or higher).
