Hi Tony,
Awesome! I'm Nick from ROCKI.
You can play music to more than 1 ROCKI but currently they can't play in sync yet.
We are developing the MultiSync function which would sync the ROCKI's to play the same music together in sync. We are very close to completing the function (all ROCKI's would be automatically updated over internet once the function is ready). We expect to release a Beta version of the software to our Beta community. If you are interested in having the beta for your ROCKI's, you can send an email to beta@myrocki.com with "multisync" in the subject.
Feel free to ask any questions!! ROCKI on!!
Cheers,
Nick | ROCKI
