ABSTRACT:
A system for expeditiously rejuvenating conventional old keyboard musical instruments to MIDI standards at low cost is disclosed. One or more linear arrays of key actuation sensors and a printed circuit board carry the key actuation sensors for sensing key actuation and expression effects by a musician are mounted above the keyboard of the musical instrument by a rigid mounting bar to convert each key actuation and expression effect of the musician to first coded electrical signals, respectively. Each key actuation sensor incudes a device for individually vertically adjusting the sensor relative to the mounting bar.
