Abstract
The present invention is a circuit for controlling the sampling of plurality of channels in an electronic organ having multiplexed keying. The channels having information signals at a particular time period is sensed and used to address a memory. The memory has stored a plurality of sequences of digital signals for controlling the multiplexing and demultiplexing operations of the organ. Only those channels containing information signals are sampled which accordingly increases the sampling rate which increases the frequency of the harmonic component of the square wave signals that can be passed by the system and the distortion caused by aliasing of harmonics is diminished.
