Ultimate Control is the ONLY music control device with a custom designed remote control. This is not a key fob for your jet ski. This is a custom designed remote made for entertainers. Works in your pocket. Raised buttons and fade out button on the side of the remote so a quick squeeze fades or starts your music. Features in the mp3 player are made for entertainers too. Each song can play thru to the next one or cue up the next track and wait for your command. Individual track volume can be programmed for each track. A song or sound effect can be used more than once per playlist. No need for blank tracks or long waits after fading out. No need to use your phone or computer for your show. Everything you need fits in your shirt pocket!
