A New Prophet with Deep Roots

The Sequential Prophet-6 is Dave Smith's tribute to his groundbreaking analog polysynth, the Prophet-5. Says Dave: "It's not a reissue, it's vintage with a modern twist." Driving this 6-voice beast are two discrete VCOs plus a sub oscillator per voice. Other features are two discrete filters per voice, a studio-grade, digital dual effects section, analog stereo distortion, onboard arpeggiator and step sequencer, a knob-per-function top panel, and a full-size, 4-octave, semi-weighted keyboard with velocity and aftertouch. We Sweetwater synth aficionados are ecstatic over Dave Smith Instruments' Sequential Prophet-6. You will be, too!

Dave Smith Instruments Sequential Prophet-6 at a Glance:
  • Pure, cutting-edge analog: modern, yet classic
  • Studio-grade dual effects engine
  • Poly Mod and polyphonic step sequencer
  • This synth is amazingly easy to program
  • And it's even easier to play
Pure, cutting-edge analog: modern, yet classic

At the core of the Sequential Prophet-6 are two newly designed, discrete voltage-controlled oscillators (reinforced by a sub oscillator) per voice. These modern analog oscillators feature continuously variable waveshapes with triangle, sawtooth, and variable-width pulse waves. Two discrete filters per voice give you Michelangelo-class tone-sculpting prowess: a four-pole, resonant lowpass (inspired by the original Prophet-5 filter), and a two-pole, resonant highpass. Voltage-controlled amplifiers complete the Prophet-6's pure-analog signal path.

Studio-grade dual effects engine

The Sequential Prophet-6 sports a dual effects section that delivers studio-quality reverbs, delays (standard and Bucket Brigade Device - aka BBD), chorus, and phase shifter. Although the effects are digital, with 24-bit/48kHz resolution, true bypass maintains your pure-analog signal path. Also onboard is a 100% analog independent stereo distortion effect. In the early '80s, the Prophet-5's polyphony and patch memory were huge technological achievements; onboard effects were nothing but a pipe dream (if that). Kind of makes you appreciate the age we live in all the more, no?

Poly Mod and polyphonic step sequencer

The Prophet-5 rocked a feature called Poly Mod, and so does the Prophet-6 - with enhancements, of course. As with its predecessor, the Prophet-6's modulation sources are Filter Envelope and Oscillator 2 (both with bi-polar control). Destinations include Oscillator 1 frequency, Oscillator 1 shape, Oscillator 1 pulse width, lowpass filter cutoff, and highpass filter cutoff. Unison mode (featuring configurable voice count of 1-6 voices and key modes) also makes an encore. The Prophet-6's polyphonic step sequencer accommodates up to 64 steps and up to six notes per step, letting you build sequences polyphonically, with rests and external MIDI clock sync. There's also a full-function arpeggiator that you can sync to external MIDI clock as well.

This synth is amazingly easy to program

Dave Smith designed the Sequential Prophet-6 with a knob-per-function top panel that gives you instant access to virtually all its functions. You get 500 permanent factory programs, arranged in 10 banks of 100 programs each. You can, additionally, create and save up to 500 user programs. Toggle off the Preset button and you're in Live Panel (what you see is what you hear) mode, in which the sound of the Prophet-6 switches to the current settings of its controls.

And it's even easier to play

Dave Smith Instruments equipped the Sequential Prophet-6 with more than awe-inspiring sound. To inspire your creativity, this formidable synthesizer is fitted with a four-octave, semi-weighted keybed. Four octaves is, in our humble opinion, the optimal compromise between two-handed playability and portability, which makes the Prophet-6 your ideal gigging buddy, particularly when you factor in the instrument's tour-tough build quality. These keys, which are velocity and channel-aftertouch sensitive, feel silky smooth and just beg to be played. So go ahead - sit down for a sound design session with the Dave Smith Instruments Sequential Prophet-6. We promise, you'll be hooked!

Dave Smith Instruments Sequential Prophet-6 Features:
  • All-analog signal path; discrete VCOs and filters
  • 6 voices; 2 voltage-controlled oscillators plus sub oscillator per voice
  • 2 discrete filters per voice: 4-pole resonant lowpass and 2-pole resonant highpass
  • Digital dual-FX section (true bypass maintains a full analog signal path)
  • Multimode arpeggiator; 64-step polyphonic step sequencer
  • Full-size, 4-octave semi-weighted keyboard with velocity and aftertouch
Dave Smith Instruments Sequential Prophet-6: essential!

Just amazing...

I've had my Prophet 6 for about a month, using in the studio and on stage with my band. I've never heard a more beautiful-sounding synth (and I've owned plenty over the years). The Prophet 5 was always my dream synth, so owning this is sort of a dream come true...it's that good. I wish I'd bought it when it first came out, but have it now and couldn't be happier.

I won't repeat the many great comments that have already been made; I'll just add that if it's smooth and creamy analog with the ability to get really loud and nasty that you're looking for, this is your keyboard. It makes me smile everytime I play it, and I can't ask for more than that. As always, the Sweetwater experience was perfect. :)

Professional Producer's Dream Poly

I produce a variety of music full time and after waiting for several years, bought a prophet 6 from Cody here at sweetwater. I tried the Prophet 5, UDO Super 6, and Prophet 6 at a local synth shop and felt conflicted between the P5 and P6 immediately. Super 6 is for another year and is altogether a different vibe. I trusted my instincts and went with P6 for a more modern workhorse synth. I can tell you that this was absolutely the best choice as since I got the unit it has found its way into every song I've made for the past month. It can be bright and loud, soft and mellow, all the while keeping its "alive" feeling analog goodness. The stereo effects and Stereo pan knobs are essential for today's music. Needless to say, if you want a staple poly synth for the modern studio you can't go wrong here. Kpop, EDM, Pop, Country (fake slide guitars), indie - it can find a home in any track. Thanks to cody for making this purchase easy and sweetwater for their support and efficiency.

PS: pairs with a Moog Sub37 beautifully, and J3P0's patches give you instant amazing sounds :)

Love the Prophet 6

Was contemplating on getting a Prophet 5. Glad I got the 6 - Have used many vintage synths most won't see in their lifetime... Have compared this to an original prophet 5... I know there are some synth junkies that will be mad at me for saying this.... BUT MODERN SYNTHS ARE THE NEW WAVE. Not saying there aren't any vintages out there I would love to have (Model D, OBXA etc...) But as far as sequential circuits goes, one of my favorite synths ever. The possibilities are endless, and you really understand why people always reference "it's like digging for gold".

Get lost in the synth, experiment, turn some knobs... and sometimes magic happens.

I produce Deephouse... this is my go-to synth for inspiration.

Happy in Vermont

When the new Prophet 5/10's came out, I was already struggling with the decision to get the 6 or maybe something less expensive (since I'm a child of the 70's & 80's). I was lusting after a Prophet like most other bedroom musicians in their 50's and had been wanting a 6 really, REALLY, badly. Knowing that a 5 was a possibility made pulling the trigger exponentially difficult. I went with the 6. I won't bore you by telling you how great it sounds, just suffice it to say it has exceeded my expectations in that area. Yes, it is a solidly built, beautiful, and classically-appearing work of art (inside and out). Plus I actually LIKE having 49 keys rather than 61 and and the extra bells and whistles the 5/10's lack was the deciding factor-and of course the $-in purchasing this desert island synth. I'm very please with it. BTW Dave Smith has made the vintage knob found on the 5/10 available for the 6/OB6, very righteous of Mr. Smith I might add.
