<p>A recording and playback system for keyboard musical instruments in which data characterising the operation of a keyboard of the instrument is recorded in solid-state memory in the form of words specifying keys for which changes of state have taken place together with data words specifying the time intervals between such changes, both types of data words being recorded in a continuous sequence of addresses in memory and the timing signals being distinguishable from the changes-of-state signals by the use of pre-arranged codes, different for each type, within the range of codes available for use as data codes; such data being subsequently played back by the system in such a manner as to cause the musical instrument to reproduce the original performance.</p> |
