This is a relatively new feature! Do it now so you can get 5 free melodician for making an account, and it backs up your data too!
First of all, go to the Menu screen on the bottom right of the app, and select SB69 ID.
This screen will pull up. The options are as follows:
(Old) Enter change device password
You’ll want to select the 1st button.
Then this screen will appear. The first field is for your username (must be 4-12 characters long), and the next two fields are for you to create a password (must be 6-12 characters long and contain at least 1 number), and then confirm that password by entering it again. Once you’ve completed the three fields, hit the button at the bottom to proceed.
At this point, the screens should be relatively self explanatory, I believe. Please remember your password!
Once you’ve created your ID and it’s all set, enjoy your free melodician. Also, now the screen will look like this. The options now are as follows:
Login to a different account
Be careful logging in, because that account’s data will replace your current account. You can probably recover your original account by logging into it again. I haven’t tried logging into other accounts though so I can’t give any solid advice on that, so be careful!
If I’ve missed anything or you would like further clarification, please feel free to ask!
