Upright Piano is a free virtual instrument that delivers the authentic sound of an upright piano through expertly recorded samples by Rudi Fiasco. It includes four sampled notes per octave and six velocity layers for each note, ensuring dynamic and expressive playability. The stereo recordings add depth and realism, while key release samples enhance the natural decay and resonance of the instrument.

This plugin offers intuitive controls that allow users to shape their sound easily. It includes adjustable attack and release settings via a volume envelope, a tremolo effect with speed and modulation depth adjustments, and a built-in low-pass filter to refine the tonal character. Additionally, a reverb effect adds spatial ambiance, and users can control both the key release volume and the overall output volume for precise mixing.

Available in 32-bit and 64-bit formats including VST, VST3, and AU plugins, Upright Piano is compatible with a wide range of digital audio workstations. The download size is 596 MB, with an installed size of approximately 1.23 GB, making it a substantial yet accessible instrument for producers and composers looking for a realistic upright piano sound without cost.
