When you're using a router, there's no limit to the number of devices the software can connect to but you will be limited by the performance of your router and computer and your venue layout. You can read more here. If you're playing over the internet you're limited to 100 devices.

Do I need access to the internet during my event?
If you're playing over the internet you need a good stable internet connection so we recommend connecting your computer using an Ethernet cable. If you're playing locally with a router you don’t need an internet connection during your event but you do need an internet connection to authorise your licence and we strongly recommend doing this several hours before your event.
