NAMM 2015: Update: Video of Sequential Prophet-6 in action

NAMM 2015: We were sort of expecting Dave Smith to rock up to the NAMM Show with a new synth, but the news that Yamaha has gifted him back the Sequential brand name ("To say that I'm grateful would be putting it mildly," says Smith) and that he's putting it on a sort-of-sequel to the legendary Prophet-5 has caught us off guard.

Explains Smith: "The Prophet-6 is a tribute to the original poly synth that started it all - the Sequential Prophet-5. But more importantly, it's the culmination of our effort to build the most awesome sounding, modern analog poly synth possible. It's not a reissue, it's vintage with a modern twist."

So, many of the Prophet-6's specs are similar to those of the P5 - it has a completely analogue signal path with discrete voltage controlled oscillators, filters, and amplifiers - but there are also enhancements.

There are additional modulation destinations, for example, and also a dual effects section, a multimode arpeggiator, and a polyphonic step sequencer with up to 64 steps. The keyboard is velocity-sensitive and supports aftertouch, and its four-octave size was chosen to satisfy both gigging and studio musicians.

Check out our video of the Prophet 6 live from the show floor with the man himself, Dave Smith, and drool over the specs below. Plus check out our gallery of pics and hands-on with the Prophet 6 here.

Expect release in the second quarter of the year and a price of $2,799.
