Didn’t find this answer before.. Thanks for the FAQ .. I’m gonna ask the seller …
Q: How can I get the license transferred when I want to buy/sell a used BCR+Zaquencer?
A: When buying/selling a used BCR+Zaquencer, a license transferral is important if the new owner needs to contact our support or to get updates from our website.
To get the license transferred we need a short email from the seller to support@zaqaudio.com about wanting to transfer the license, specifying his order number, order email, challenge and response codes and the “destination” email adress and name for the transferral. Please note that we only support transferring a license between users on the same device. You cannot sell your license of the Zaquencer firmware independent of the BCR.
