True Keys is a Piano Virtual Instrument. It was created by recording nearly 50,000 audio files using some of the best microphones and recording equipment available today. Then, the audio files are matched to their corresponding piano, note, microphone position and velocity to build an electronic version of the piano. Next, the audio files are loaded into a software playback device called an engine that runs on a sophisticated scripting language to mimic the natural sound and playability of a real piano.

Traditional keyboards that have piano sounds built-in are typically built from modeling or by using samples. Models are mathematical representations of sound much like a synthesizer. A modeled piano is essentially a very large math equation used to mimic the sound of a piano. Samples are based on real recordings of an instrument.  True Keys is built using real audio samples in every aspect of the software.  From the individual microphone positions to the samples sympathetic resonance.  Everything you hear is real.
