Adding an Independent Tracking Output to the 4780 Sequencer



I have added an extra stage to the sequencer which allows two VCO's to be used with a constant pitch offset on one of the VCO's. This is similar to using a 4781 Transposer on the output of the sequencer, except with this modification individual glide times can be set for each oscillator. This can be used to cause the oscillators to detune when changing from note to note, and after a short time they will resolve to the properly tuned interval.

The circuitry is actually a duplication of the original output stage of the sequencer. I don't believe that several of these output stages would overload the sequencer. I mounted my extra circuitry behind the blank panel of the 4700/A Sequencer Pac. The blank panel can be used to mount the glide and transpose controls and the output jack.
