Continuing the trend of launching “remakes” of their own vintage instruments, Roland released the VP-550 in 2006, and three years later the VP-770, to keep the spirit of its 30 year-old predecessor, the legendary VP-330 Vocoder keyboard alive and well. First impressions are very good. The VP-770 is reassuringly heavy and seriously ‘pro’. With its solid metal chassis and some vintage 2009 wood end panels, it feels like it could stand any abuse thrown at it. Outfitted with onboard mic preamps and Vocal Designer functionality, the VP-770 allows you to conjure everything from realistic backing vocal parts to large choirs to wild electronic textures with your own mics or the included headset mic (which allows for hands-free singing while you play and program). The Roland VP-770 49-key vocal and ensemble keyboard lets you create amazing multiple vocal harmonies and much more!
According to several user reviews, they have praised a Roland VP-770 for the Well-built with plenty of connectivity and control; High quality and great sounding vocoder with highly realistic vocal designer backing; A doddle to use. Also, some users have complained it for A few more effects would have been nice, as would some bass sounds.
