Spindle
SINEfactory instrument—free with registered account

Free felt piano
Spindle is a Rösler upright studio piano with soft-felt hammers, producing a gorgeously muted sound. Recorded up-close and intimate, from four mic positions—the low end tones are warm and round, with lots of detail in the high-end. Includes three velocity layers with three round-robins per note, making it well-suited for repetitive ostinatos and sparse arrangements. Channel your melancholic nordic noir, or add a touch of improvisation to electronica or beats.
