Preset systems usually rely on:

1) storage of parameters in digital form
2) an analog to digital converter to pull analog signals into digital form
3) a multiplexer (or two) to select analog signals that are to be sampled
4) a digital to analog converter and multiplexers to send the digital values back to the analog controls

All of this assumes that each analog control is voltage based.

hello folks,
as i'm about to start building an analog synth, i'm also
wondering if it'll be feasible to have a preset system and
design it around that. it isnt something i know about, and
i'd like to read up on it.
could you point me some sites where i can get the relevant
information?
you can email me directly at domgoold@yahoo dot com
thanks for any help.
