Yes, I received this reply on April 11th:
Please try the attached instruction to clear the 5508 before you do the MultEQ Pro calibration.
Completely clearing the Audyssey Pro settings from an Integra/Onkyo 2010 model the procedure is below.
This works on:
1) Set the Volume to Default Level:
2)Push and hold 'Memory' - then push 'Standby/On'
There will be some weird text on front panel display at this point. Press 'Return'.
3) It will show "All Clear??", then press 'Return' again.
Update: I can confirm this "all clear" restores MultEQ Pro functionality.
