Abstract
Abstract A tape recorder is variously connectable by switching to one or more parts of the electrical circuitry of an electronic musical instrument, the switching being readily controllable by the instrument player, whereby a musical piece being played can be recorded and subsequently reproduced through a part of the circuitry and the loudspeaker(s) of the instrument, and, moreover, the instrument can be simultaneously played as a recording is being so reproduced through the same loudspeaker(s).
