I don’t know if this will help anybody. But I’m posting this as a record of how this unique problem was solved.
Here is the procedure, to restore an H9 Max de-registered by a party other than the owner (including the additional variable of a second, algorithm-sharing H9 Core). The condition was a deregisterd H9 Max, that was not deregistered in it’s associated H9 Control. Cannot re-register because it is already registered in H9 Control. Cannot de-register, because it H9 Control reports it is “registered to another owner”. Both pedals reporting “No Algorithms”.
- Clear account settings on H9Control device (eg. iPad).
- The H9 Control will continue to report the H9 Max as registered. It will not permit deregistering, because it detects an H9 Core that may be sharing algorithms.
- Log into the Core, restore it to factory settings and turn it off.
- Clear account settings a second time in H9 Control.
- Deregistered the H9 Max, and log out of H9 Control.
- Log into H9 Control. It will detect the H9 Max.
- Register H9 Max to the Eventide account. H9 Control now recognizes the local owner.
- I logged out and back into H9 Control.
- H9 Control will find the H9 Core, and allow it to be registered ito the Eventide account.
- Restore both H9 backup files.
- H9 Control will now accurate ownership, registrations, and bundled algorithms
- Log into eventideaudio.com and check My Products. If it reports accurately, you are set. If it reports inaccurately, contact Eventide. technical support. They have the ability to correct their database.
