A MIDI musical instrument (10) includes a set of force sensitive transducers (12), arranged as a keyboard. The keyboard is electronically scanned and the identity of the key or keys being depressed, along with information relating to the velocity of that key depression, are stored. Stored tables in memory (28) convert that information to MIDI standard information relating to pitch and velocity for MIDI compatible tone generators or to MIDI messages for a MIDI event. The tables may be standard tables employing chord voicing information, individual note information, or other information relating to the MIDI events to be implemented. The tables switch in real time at a speed sufficient to seem transparent to the user, thus allowing dynamic reconfiguration of the keyboard during the performance of a musical composition. In a preferred embodiment, the tables are arranged such that during the interval of time in which a particular chord is being played, the depression of any key (202-340) will result in the generation of a ''correct'' chord or a ''correct'' note in a scale which is compatible with that chord. The keyboard may be operated at 100 percent efficiency because the keys may be defined such that they are all utilizable at any time during the performance of the musical composition. |
