Odd Yamaha delated by "Easter Egg" post noting one of the most amazing things the new YC voices can do which is using the EG and Filter knob to dramatically change the new FM/DX voices. Why wouldn't Yamaha want that information made known to make the update even better? Guess they were offended by the compliment. Not sure how/if the phase "easter egg" discloses top secret information or creates a false expectation but there's nothing offensive about a hidden feature that should be discussed openly.
