Hi juergenbranz, the H9 Core only comes with the H910/H949 algorithm from factory. When a user removes a pedal from their Eventide account, an H9 reverts to its factory state. Individual algorithms that have been purchased by one user do not travel with the pedal to a new account if sold.
The only time this is not true is when a user has converted an H9 Core to an H9 Max using the Max-Out process, where they pay a one-time fee to have Eventide convert it in their system. At that point, the pedal ceases to become a Core unit and is configured to be a Max with all 52 algorithms. In this case all the algorithms do travel with the pedal from user to user. Right now, there is an ongoing Max out promo at its lowest price ever, so that may appeal to you. There’s an upgrade link in the middle of this announcement page: https://www.eventideaudio.com/one-h9-rule-them-all
