V-4 for VJ
If you haven' t been out clubbing recently ( that' s what the kids call " going dancing" these days) , you may be surprised to find a Video Jockey ( VJ) mixing live video to the beat and feel of the music being spun by the DJ. These visuals are a prominent part of the club experience and some bands, large and small, incorporate video into their live performances. This is what the V-4 lives to do. The prominent BPM ( beats per minute) display along the top of the unit, with the Tap button alongside let you time effects and transitions to the beat of the music.
You can also trigger the V-4' s effects remotely via MIDI or Roland' s proprietary V-Link protocol, which means that a musical keyboard ( synthesizer) , sequencer or computer ( such as Edirol' s DV-7PR) can control the video effects. This gives performers using electronic instruments great flexibility in controlling live visuals on stage.
