If someone is using the Microsoft Store to use one purchase on multiple devices that they are not using personally, that is against the terms of service of the Microsoft Store, as you are not supposed to be sharing purchases with other users (this also hurts developers and ongoing support). For users in that situation, they should be purchasing individual licenses per musician through my FastSpring store here: https://zubersoft.onfastspring.com/

It's perfectly valid to use a single purchase for all of your own personal devices though.
