We recommend that you use the same button layout in each room, even if a room does not have any secondary functions such as blinds and music - simply leave the buttons unconnected - you never know what you might want to add in the future.
Having flexibility is the key to future proofing your smarthome.
All TAP-5 buttons support multitouch, and we recommend that you use the middle button to control your lights with the following functionality:
Single-Click: Cycle between your customized lighting scenes.
Double-Click: Turns your whole room off, including lights, music, HVAC…
Triple-Click: Turns your whole house off, including lights, music, HVAC…
The four corner buttons can then be used to control the other automated functions of your home such as music and blinds. If you just wish to control music then you could add extra controls such as play/pause, instead of blinds up/down.
If you want to get advanced then why not add some extra controls to the play button using double and triple click (same as apple headphones)
