Grand Piano XXL 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.
All the samples were captured in 48kHz 24bit audio quality with 16 velocity layers which are all present in this virtual plugin, hence the 1.19 GB size on disk.
The keys release samples are also added in Grand Piano XXL.
There’s also a smaller version with only 4 velocity layers, called Grand Piano.
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.
