Free Upright Piano VST Instrument Released by 99Sounds

99Sounds returns after a long break with a new free release – Upright Piano, a piano virtual instrument ROMpler for Windows and macOS.

Upright Piano is based on a set of upright piano samples recorded by Rudi Fiasco. It features four sampled notes per octave and six dynamic layers per sampled note. The samples were recorded in stereo. Key release samples are also included.

We find a quite simple interface with volume envelope (adjustable attack and release time), tremolo effect (adjustable speed and modulation depth), a built-in low-pass filter, and a reverb effect. The key release volume and output volume can also be adjusted by the user.


  • Attack/release control.
  • Tremolo/filter/reverb control.
  • Volume/key release control.
  • 596 MB download size.
  • 1.23 GB size on disk.

Upright Piano is available in a VST/VST3, and AU plugin formats (32 & 64-bit) for Windows and macOS.
