PURPOSE:To provide the musical performance information detection system for the electronic musical instrument which can multiplex a musical sound select signal and a function select signal together and also sample them at a proper period neither excessively nor insufficiently as to the musical performance information detection system of an electronic musical instrument having a means which multiplexes and scans a musical sound select signal from a key switch and function select signals from a tablet, an analog variable resistor, etc. CONSTITUTION:The electronic musical instrument equipped with plural key switches 3, plural analog variable resistors 6, and a microcomputer 1 is so constituted that the microcomputer 1 scans all the key switches and some of the analog variable resistors 6 in single main routine processing and scans all the analog variable resistors 6 by performing the main routine processing plural times. |
