state counter 30 and flip flop 32 state counter 30 advances sequence memory 22 through the sequence selected by sequence selector 26 and sends a gating bit to gating circuit 34 state counter 30 provides an address for a particular part of the musical selection selected by the sequence selector 26 corresponding to a single 34 chord 34 or state of the keyboard scan cycle this state incorporates the up or down condition for every key in a given keyboard flip flop 32 represents to gating circuit 34 the fact that the key or switch being actuated by the operator is up or down gating circuit 34 also receives information from on off switch 36 which selects automatic playing 34 autoplay 34 or normal playing mode the operation of an electronic organ equipped with the apparatus of the first embodiment of the present invention can be briefly summarized as follows the operator selects the desired registration or stop combination in known manner and independently of the present invention and then places the organ in the autoplay mode by means of auto on off switch 36 the operator then selects the desired musical sequence by means of the sequence selector 26 and activates the reset switch 42 to reset the state counter 30 when the operator presses the play switch 40 the organ will sound the first chord of the musical sequence until the switch is released when the operator again presses the switch the second chord will sound until the switch is released the action continues thus until the musical selection is finished the operator may at any time return to the beginning of the selection by activating the reset switch or change musical selections by changing the setting of the sequence selector 26 rhythm and.
