[sdiy] looking for common methods of controlling cv lines digitally

[wayfar]

Hi,

I hunted through the memory moog, the prophet 600 and the juno 600 
shems, and it looks like they all use exactly the same method to control 
the osc control voltage lines. Which is using a DAC connected to a 
series of 4051 demux, when are then connected to an array of cap / opamp 
buffer sample and hold circuits.

Are there any other techniques that are common for digitally controlling 
analog lines, like for digital patch recall / editing ect?

Thanks,
