Korg nano kontrol with max

Hi all, not sure if there is already a post explaining this, i've looked but cannot find anything.

I've been given a patch that creates colour visuals with audio data. I'm planning to use it in a performance at uni and would like to customise it specifically for control of hue,saturation and colour. My plan is to use the nano kontrol to allow audience members to do this.

Does anyone have any suggestions on what objects would do this and how to get the nono kontrol to work in this way.

Any help would be great.

Regards

Jonny
