We offer guest checkout which doesn't require creating an account. However, you will need an account for the following: registering your device, using set list function, purchasing from the score store, or using My Library which allows writing on to scores, group management, and using the share function.
Please note that you may register only up to 3 devices per single GVIDO account. If you need to register more than 3 devices, please contact Customer Support to have a separate company account issued.
