ABSTRACT:
A keyboard operated electronic musical instrument is disclosed for imitating the strummed and solo modes of playing plucked fretted musical instruments. The actuated keys do not directly control the set of tone generators, but are used to automatically select one of a library of chord types which is closest to the actuated keys. A root note is chosen for each selected chord type. The selected chord type is transposed to an open chord spanning the several octaves associated with a guitar-type instrument. The selected tone generators assigned to the transposed open chord are strum keyed in sequence at a rate adaptive to the speed in which successive chords are entered on the keyboard. Provision is made for up-down strumming and to automatically enter a solo tone mode when a sequence of single notes are entered on the keyboard.
