Abstract

PURPOSE: To obviate detecting of a new code even if this new key code is formed after codes have been established by providing a memory holding means which inhibits periodical clearing of code signal detecting memory and holds its memory until keys are newly depressed in keyboard.
CONSTITUTION: A key coder 100 detects the operating condioton of respective key switches and function switches of a key switch and function switch group 1 and forms necessary key code data. A channel processor 200 assigns the key code data having been formed with this key coder 100 to any of plural sound producing channels and generates data for forming arpeggio sounds. The data having been sent from the channel processor 200 are applied to a digital tone generator 400. The musical tone signals having been generated from the digital tone generator 400 are given with timbres by passing through a timbre forming filter circuit 500 and are produced from a sound system 600.
