99Sounds Releases FREE Upright Piano VST/AU Plugin


99Sounds introduces Upright Piano, a freeware piano instrument in VST, VST3, and AU plugin formats for digital audio workstations on PC and Mac.

Upright Piano is based on a set of piano samples recorded by Rudi Fiasco. These samples can be downloaded in WAV and SFZ format from his website. To learn more about the source simples, visit Rudi Fiasco’s website or read BPB’s news article about the release.

The plugin features four sampled notes per octave and six dynamic layers per note. The user interface provides direct control over the envelope, key release, volume, tremolo, filter cutoff, and reverb. A built-in keyboard is also included.

The instrument sounds realistic out of the box, but it can also sound lo-fi and wobbly when the built-in effects are applied. It can work equally well as an authentic upright piano instrument, or as a processed piano for use in styles like lofi hip-hop and urban music.

99Sounds is Bedroom Producers Blog’s sister website. It is an indie sound design label featuring the work of fellow sound designers from across the globe.

  1. Great, neat little package, this plugin version of Rudi’s Upright with additional controls. Thanks so much to all involved in making this plugin.

    P.S. If I may ask: since I’m in the process of creating a free library, which software was used to create the sample mappings and settings? Is it based on Maize Sampler, HISE, SFZ … ?

  2. I’m using this with a rolaland 76 note keyboard but can’t play upper octaves so it sounds too low. Is there a way to alter the octave so I play higher range notes from my keyboard

    • Make sure you place the folder with the .instruments extension alongside the .vst/.dll file, it should work like a charm.

  3. Many thanks for this.

    However, I cannot get the Upright Piano to play in tune – other virtual pianos are working fine, but Upright Piano is not.

    Any ideas?

    Thank you.
