Two pots on the same pin

Hi guys, newbie here. I was wondering if anyone can help, Im currently building a digital synthesizer. I currently have a potentiometer on A0. Im looking to add a small xy joystick, salvaged from a game control pad. How would i add this to the pot on A0. I want to be able to use the pot to set a level and use the joystick for momentarily boosting this level. Im not too sure, but i think i need to use an op amp for this.
Does anyone have any ideas or can point me in the right direction.
Thanks in advance.

You can connect two potentiometers to one pin, but you can only use them one at a time.

Hi, thanks fo the quick response. For some reason i was thinking an op amp could be used, not sure why. Back to the drawing board I think.

Wouldn't it be easier to use an analog multiplexor?

You would need an analog multiplexer to use more than one potentiometer on a single pin.

Is there some reason you cannot use a different analog input for the 2nd potentiometer?

I will probabily use a multiplexer. I just wanted to see if it could be done. Just me being lazy really, I didnt want to change any of the code. Cheers guys.
