I've just cured a very noisy volume potentiometer on my Alesis Micron.
I just thought I'd post this for othe Micron owners, as it's quite a common problem.
There is also quite a bit of info on the internet advising against using switch cleaner to cure the noisy pot, as the pot is supposed to be a sealed unit, and the only cure is replacement.
On the contrary, I opened mine up to reveal a pot with holes in the side and top, I simply sprayed a bit of cleaner in and all was fine, no more noise.
I know there were slight design differences between early and later models, but it's worth having a look, just to see if you've got a sealed unit or not. Another source of noise on the output is a VCA issue, but luckily it wasn't that this time, and the switch cleaner was an easy fix.

If you have cause to take one of these apart it's built like a tank, about 20 screws holding the bottom on! Take a picture with your phone, I got the screws muddled up and the air was a fetching shade of red for awhile!
The PCB with the pot on it is at least, easy to access.
