ABSTRACT:
There is disclosed a system for demultiplexing and storing time division multiplexed frames of musical data encoded ina bi-phase mark/space code. Data in sequential groups of data bit cells is stored in a shift register while a counter counts the data bit cells. A plurality of latch circuits, each capable of storing one said group of data, are sequentially enabled to receive and store the data, in the groups, respectively. After all of the data bit cells in a given time frame are stored, they are simultaneously gated to transistor driver circuits for operating solenoids which, in turn, re-create the music.
