Cra-Z-Art Soundmoovz Music Player, Black

After you download the app and choose music... does it work alone or need to be within reach of the bluetooth device?

bluetooth device? a phone?

Can this be paired with a kindle fire? Also, once the app is downloaded, does the paired device need to be around at all times for the bands to work?

Can i connect it to my pc via bluetooth to use is as a midi controller in my production/beat-making software? i'm having trouble connecting it to a pc
