Is there a device i.e, an IC, processor, etc. that would act like a 360 deg turn pot with multiple taps (4 or 8) that would vary from highest to low/no resistance between the taps 180 degs from each other. Need to be able to vary the speed of "rotation" and the speed of "ramping up" to max "rotation" and "ramping down" to minimum rotation. this is and audio application so noise limitation is critical. I've looked at electronic sequential switching as in light "chasing circuitry but there need to be a smooth transition between the loads (as in riding on a sine wave). Please review the attached jpeg. Thanks for any help/suggestions.
