Hi! I accidentally stumbled across an easter egg in the desktop version of Caustic. I did a quick search and did not find any mention about it in this forum. If you press a keycombination, a new window with a spectrum analyzer will appear. On my swedish keyboard it's the combination of ctrl+ö, but I think that a english keyboard will have a ; at that place. It's however the third key from the return key in the middle row of the keyboard (the "asdfghjkl"-row).
I found it because I thought another window was active while pressing that keycombination ;)
