Grand Piano Free ROMPler

Grand Piano


Grand Piano is a free virtual piano instrument plugin (ROMpler) featuring a sampled Yamaha C5 6’7″ Grand Piano.

The original samples (Creative Commons Attribution 3.0 license) were recorded by Alexander Holm [axeldenstore (at) gmail (dot) com] with two AKG c414 condenser microphones placed in an AB position at around 12 centimeters above the strings.

The difference between Grand Piano and Grand Piano XXL is that this version has only 4 velocity layers compared to the XXL, resulting in a smaller size (319 MB).

The GUI is simple and intuitive with attack & release controls, reverb module, and gain. In the middle, there’s a “Tremolo” section with LFO rate & depth for pitch, expression, and pan, plus filter cutoff with selectable lowpass/highpass. You will also notice a “Key” knob – that’s the gain for piano keys release.
