With Monster GO DJ, DJs and music producers are now able to play and record music virtually anywhere as long as they have headphones or speakers. DJs can cue, loop, beatmatch, scratch, and mix music accordingly. Producers can create beats using the drum pad machine, step sequencer, and recording functions. GO DJ comes with 4GB of internal storage but is capable of holding up to 2TB of music. It has a 12 hour battery life with a lithium ion battery.
