Wrong with the tetromino translation

As discovered by a person on the Xbox360Achievements forum in this post, this puzzle can be solved just like the first puzzle in the same room. The following picture shows the floor of the room, which can be seen in first person view:

The first puzzle required a button input sequence while standing on the square with no line in it (circled in blue in the picture). This puzzle similarly requires standing on the square with a line in it (circled in green in the picture) and inputting the following button sequence.

The left and right motors in your controller will play a pattern when approaching these. It will pause briefly before repeating. You need to mime the pattern back with your left and right triggers.

My vibration was off, so I missed this the first time through. If you're having trouble, the right motor was a higher pitch in my case. Instead of feeling the sides, I listened for the pitch.

As far as I know, across ports, you can't solve this on your own without a vibrating controller.

Here are the codes, if you're lazy or without:

• Waterfall neon pink/blue subroom tuning fork: LT RT RT RT LT RT RT LT
• Lighthouse tuning fork: LT RT RT LT LT LT RT RT RT RT
• Sewer tuning fork: LT LT LT RT LT RT LT RT
• Lava tuning fork: LT LT RT LT LT RT RT RT
