There isn't any one solution or "correct answer". It's just whatever you do on one terminal screen has to match the other that's all. So you can do one high note, two low notes, and one mid note on the left and then on the right screen you have to path to the small dot first, then the two big dots, then the medium dot.

big dots= down, small dot= up, medium dot= middle. Then go by same order. There's multiple solutions

I made a pattern on the right panel with the dots that I could replicate on the left panel. That's my interpretation, anyway..

I think you need to listen to the steps going up and down the stairs. climbing up - you hear a knock like 4 feet. And also going down to the bottom, but the other 4 sound. But I'm not sure, because I already know the answer to the puzzle.

how did you get these answers?
