1. There are however some exceptions when latency is built into the mechanism of an instrument. In the case of a piano, the delay between a key reaching the key bottom and the hammer striking the string can be around 35 ms for pp notes and -5 ms for ff notes. These figures do not include the key travel time (the time elapsed between initial touch and the key reaching the key bottom) which for pressed touch can be greater than 100 ms for pp notes and 25 ms for ff notes (Askenfelt & Jansson, 1988).
