*Robert Finley is a British pianist, now living in USA for work. Being a virtuoso soloist, he preferred anyway to follow the vocation for electronics and he found a job in America. But he still loves and plays music: Robert Finley's site
Every single hammer that hit piano's strings during a real piano performance is a nearly un-repeatable event.
It's because of the random inpredictable combination of resonances, other keys pressed, energy, noise and speed of the mechanics and so on. Using sampled sounds the same velocity will reproduce every time the same sound, the same acoustic event.
A good reverb and resonance (e.g. pedal pressed) sampling are helping a lot, but a little predictable and repetitive effect is anyway still existing.
The quality of a good piano MIDI sequence is then to distract the audience from this weakness, with the random and musical flow of the notes.
This sequence is very well done and give us back in some moments the real feeling of a piano "live" concert. I was impressed, and I decided to share it with you. Hope you enjoy.
