摘要
A switching control circuit for keyboard electronic musical instrument allows key signal to be stored on magnetic tape. The output of any of the keys is transmitted over OR gates to power driver stages to produce the notes. The key signals are also entered into a shift register and are clocked at a controlled rate into a transfer register. From the latter signals are amplified and stored in magnetic tape cassette form. Replay from a cassette is over a selector switch, amplifier and into an output register. A decoder register coupled to additional decoders, bistable and selector allows delays to be introduced to provide exact reproduction. Signals are entered into a register for transmission to the drive stages over the OR gates.
