OK a lot clearer thanks.
While you still use variables it is best to use a special type of variable called an array. http://arduino.cc/en/Tutorial/Array
This is a variable you can store many different values in.
There are many ways of doing this and perhaps the best way is a two dimensional array, but to start with you should just use a one dimensional array and have one array variable for each of the pots.
You will need a store button, your program detects when that is pressed that takes the current three readings and puts them into the three arrays using the index (position in the array) of the bank or address of that sound.
Another button when pressed will read the value in the arrays and output them in some way.
So you need another form of control that determines what bank you are dealing with at the current time. Either a multi-position switch or a rotary encoder with some sort of display.
but all of this is new to me
While this is not a difficult project it is not a beginners one. Get to grips with the language, do a few tutorial examples:-http://arduino.cc/hu/Tutorial/HomePage
Then you will be in a position to ask the right question, BUT MORE IMPORTANTLY, understand the answer when it is given to you.
