Yeah, well, sorry about the somewhat confusing title, hopely I'll describe better in here.
I got my hands on Arduino (http://arduino.cc) and got really excited. I want to experiment on using it to control some gear. Like replacing all of the controls and maybe some VU meters. Stuff like:
- Having a single tactile button that switches between compression ratios on a GSSL/1176, lighting up the corresponding LED (Using Relays)
- Having some LED arrays for Gain Reduction or Input/Output levels
- Relay true bypass (ok, no need for Arduino here, but makes stuff even easier)
- In a farfetched scenario, even replacing all the controls with digital ones using an LCD with menus and cursor buttons and stuff (just because it is possible)
- Adding Store/Recall preset functions
I can probably do all that stuff if I try hard enough, however I have one basic question. What is the best way to replace pots?
I have done a small internet search and found out there are several solutions. Some are less accurate, some are expensive, some are tricky.
I have so far read some stuff about FETs (using resistors to linearize them?), digital pots (?), some people are even using optocouplers to do such stuff and motors to control motorized pots (obviously do not want this!)
So what do you guys think? Using CV to replace pots (resistors essentially) using a microcontroller (input could still be a pot, or a rotary encoder or even buttons).
PS: I do realize that it gets even trickier if we want to emulate log pots.
