Abstract

1464997 Electrical keyboard instruments HAMMOND CORP 10 June 1974 [11 June 1973] 25665/74 Heading G5J In an electrical keyboard instrument having at least one impulse inducing percussion circuit 17, impulses are activated or inhibited by a single keying selection switch 28 that opens or closes a by-pass circuit associated with the or each percussion circuit 17. As described the keying selection switch 28 is connected to each by-pass circuit through a diode 27.
