G'day all I've designed and am in the process of making a speaker emulator for Pro Audio recording application and would like to add preset memory and midi program change to the unit. Trouble is I'm not quite sure how to go about it. I'm looking for digital control of 4 pots and half a dozen switches. If anyone could please point me in the direction of what hardware I need and how it's set up (books, articles websites etc.) it would be greatly appreciated. I did electronics at Box Hill TAFE 25 years ago and I'm just getting back into it for fun after spending years in audio sales and PC networks. Building stuff is much more fun.

** The term " speaker emulator " is highly ambiguous.Is it a loudspeaker *load* emulator - ie like a power soak with L and C components.
OR
Is it a loudspeaker *tone* emulator - ie a band pass filter with eq ??

no
Bingo
Through a number of different band pass filters I have approximated the frequency response of different common guitar speaker configurations. However, whatever the purpose/function, I'd like to be able to electronically switch between different remembered switch and pot settings via either recall buttons or midi program change commands from an external controller much like most other pro effects gear. So, can you help me with info regarding digital control of analogue circuits?
