The Ultimate Prophet-5 from Synth Legend Dave Smith

Renowned synth designer Dave Smith is back, and he’s brought with him the most powerful Prophet-5 yet! A reimagination of the iconic 5-voice polyphonic synth, the Prophet-5 Rev4 is packed with features from every iteration of the Prophet-5. It inherits its ultra-stable voltage-controlled oscillators from the Rev3 and provides you with a choice between the Rev1 and Rev2’s Rossum-designed filter or the Rev3’s Curtis-designed filter. A unique vintage knob even lets you choose from behavior characteristics of the earlier versions. With its knob-per-function architecture, the Prophet-5 never fails to inspire — just ask the synthesists at Sweetwater! To get you started right out of the box, the Prophet-5 comes loaded with a stellar selection of factory presets, and it includes 200 user slots for storing your custom-made patches. Not only does the Prophet-5 sound incredible, but it’s also contained in a collector-grade steel housing, with hand-oiled black walnut accents and end cheeks. Dave Smith and the folks at Sequential struck gold with the Prophet-5, a drool-worthy synth for analog aficionados!

Rock-solid oscillators

The twin beating hearts of the Prophet-5 are its dual Curtis analog CEM 3340 VCOs. Found on Rev3 Prophet-5s, the CEM 3340 VCOs are rock solid, with virtually no tuning drift. Their implementation in the Rev3 represented a major turning point in the design of the Prophet-5, enhancing the performance and sonic quality of the powerhouse synth. As on the legacy models, the Prophet-5 Rev4 offers simultaneous selectable waveshapes — sawtooth and pulse on oscillator A, and sawtooth, pulse, and triangle on oscillator B, with pulse width modulation on both and hard sync for shaping the timbres of the oscillators. With the CEM 3340 VCOs, you have the ideal building blocks for creating harmonically rich analog patches.

Lush, dreamy analog filters

Dave and the team at Sequential went above and beyond for the Prophet-5’s filter section. Users can choose from two authentic re-creations of classic four-pole resonant lowpass filters — the Dave Rossum-designed 2140 (a modern update of the original 2040 found on the Rev1 and Rev2), and the Doug Curtis-designed CEM 3320. The 2140 is perfect for gristly bass lines and dense, sweeping pads, while the 3320 excels at dialing in laser-sharp high end for cutting lead lines. Both filters can be driven into maddening self-oscillation, and a dedicated 4-stage ADSR filter envelope gives you ample control over shaping the behavior of the filters.

Mountains of modulation

If you’re the kind of synthesist who likes to strip things back to the INIT patch and dig into some serious sound design, then the Prophet-5 is for you! Though simple, its modulation controls give you incredible flexibility to create vintage-style basses, leads, pads, brass, and strings, or generate brain-bending textures and effects. The Prophet-5’s single LFO offers three simultaneous waveshapes — sawtooth, triangle, and square — and an initial amount control. Use the LFO for pitch modulation and PWM of oscillators A and B or send it to the filter cutoff. And assign any of the mod destinations to the mod wheel. Additionally, Prophet-5’s Poly-Mod section lets you use the filter envelope and oscillator B as mod sources for affecting oscillator A’s frequency and pulse width, as well as the filter cutoff.

Deluxe performance controls

One of the most appealing aspects of analog synthesizers is the tactile experience of interacting with their knobs, switches, sliders, and wheels — and the Prophet-5 has plenty! With a knob-per-function design, the Prophet-5 treats you with detailed control over every parameter, so you can turn patches into living, breathing performances. The mod wheel and spring-loaded pitch wheel are highly responsive and a delight to use, and the Prophet-5’s premium semi-weighted Fatar keyboard feels exceptional under your fingers. It’s ideal for taking advantage of the Prophet-5’s velocity and aftertouch capabilities.

Crank up the vintage vibe

While inspired by vintage Prophet-5s, this latest iteration boasts modern reliability and high-fidelity sonics. But what if you want to inject a little bit of old-school instability into your sound? No problem! The Prophet-5 features a nifty Vintage control knob that lets you alter the behavior according to its revision model. Keep it pristine or go back in time all the way to the rare and highly temperamental Rev1. Do you think part of the charm of vintage analog synths is their unpredictability? Then you’ll dig this feature!

Reviews

Why did I buy this 47 year old technology?
This is not my first analog synth. I have numerous software synths and digital hardware synths as well. I use the standard software DAWs to run all kinds of midi routing and plugins. So why did I decide to get this?

1.) This synth has always been on my list and has been revered for decades in the annals of music history. I have to say before I bought this synth, all this personal history with the music I loved growing up is a big reason why I bought this synth.

2.) Compared to modern synths and software synths on paper the Prophet 5 IS dated, old, not enough bells and whistles. It only has one output and no effects built in. Why did I spend any time entertaining this when I already have a software version of the same device with all the modern routing tools and effects chains? All of those doubts went right out the window and I shredded all the paperwork that shows this instrument is not worth the money, the instant I took it out of the box and plugged it in. It may not be important to everyone, but it is something to speak of for me, it just looks awesome. The walnut stain and big knobs are reason for me to want it and more so to keep it.

3.) The sound... I mean, pure, big, round, deep sound. There's tons of software versions to be sure. But it is not this.

4.) I also have the DSI Prophet 08 rev1, which is also amazing with way more features so why not just stick with that? Thanks for asking me...me. Well, when I like to create my biggest problem is focus. DAWs and software synths and mixing tools will always and forever be part of my process. But having everything under the sun at my fingertips is an issue at times. Trying to sculpt a sound with every tool imaginable whether you downloaded it for free to test or purchased outright or subscribed to -for me -takes that focus away when scrolling through countless presets and menus. NO MENU DIVING!!! It's all there. It's clearly labeled and right at your fingertips with no need to program access to those features to another device. It's purpose built to feed creativity and get to work and stay on it. That is HUGE!!!

5.) Next, Rev4 features include USB and MIDI connections and readily available parts. Finding an original classic one would be amazing if you could find it and afford it and maintain it. This is working out the box with accurate tuning and the tune feature. If I found an original and could swing it, I'ld definitely still grab it. (facepalm)

6.) I know I already mentioned the look of the knobs but they are really well engineered, smooth, and feel great. The reason I also like Moog.

7.) I'm a big fan of sound modules, space saving, and when all racked up it gives me that Reason IRL feel which is great. But this keybed is VERY responsive and the aftertouch and velocity sensitivity is quite impressive.

8.) The SOUND!!!! did i say that already??? Anyway I'm just geeking out on trying to recreate Tubeway Army. I still use my original MPC-60 to run all my midi and drums. It's old it's dated it's a more deliberate process to get samples loaded into it on floppy disks but... like the prophet 5 once its dialed in, scultping and shaping on the backend in the mix process requires way less time because I brought the sound I crave on the front end and track it with care. Now the Prophet 5 does requires some taming in the mix because it is so BIG. But man, face shredding leads and pads so lush. Curtis filters old-newer + combos... chef's kiss.

9.) I got it of course from Sweetwater and know I can always lean on Brendan, my sales engineer, for assistance when I need it.

Anyway,
You do you. Agree to disagree if you will. I'm going back to work. I think it's awesome and will have many sleepless nights at this keyboard. RIP Dave Smith. You really nailed it with brand and glad you got it back after all these years before passing on to greater glory.

My first synth; a piece of art in my room
I bought my first synth, the P5 Rev4, in July. To give some background, I am a piano player. I knew nothing about synthesis and immediately jumped into lessons with Julian Pollack, J3PO, and grabbed his preset pack (which I highly recommend). This instrument is a DEEP well. I really was looking for something that would help me fill out more acoustic productions, what I got was a piece of art that really changes my expectations for how things are supposed to sound. This instrument just SOUNDS. I don't know how else to say it.

Being new to synths, I didn't expect or understand all the features that this instrument is "missing". I would personally love a sequencer, LFO modulation stuff I can set to a specific tempo, and stereo output/FX to get wider patches, but not at the expense of the MINDBLOWING sound of this instrument, its versatility and it's sleek elegant look.

If you're looking for videos online with lush pads, smooth softbrass sounds, punchy basses, and lyrical/modern leads for the P5, you won't find a lot. BUT I assure you, they are in this instrument.

If you want to subtly move a knob and hear big difference, If you want to dial in the perfect sound, or if you want to be able to quickly move through patches and tweak, this synth has something for you.
Best synth around from the best dealer
Thank you Brian for getting this good for me! This is my favorite instrument ever
Some things are truly worth revisiting
The thing I love about the Prophet 5 is its minimalism. You won't miss things like effects and extra voices, because the raw sound is spectacular. It pulls you in and captivates. A sound to get lost in, truly. It's beautifully built and the layout is wonderful, with near knob per function, you'll be off swirling in its mysteries quickly. I own several other synths, including an OB6 (which is a great compliment to this) and the P5 is in a class by itself. Thank you Dave for reissuing and making this affordable.
P5 Rev 4 - A landmark instrument
We're living in a golden age of technology. With so few manufacturers left producing products faithful to their original incarnations, it's refereshing to see Sequential re-release this modern classic. The Cars, Hall & Oates, Kim Carnes, Peter Gabriel, Aha, Phil Collins, Japan, John Carpenter... it's all in there.

I'm simply blown away and mesmerized with this piece of analog synthesis techonolgy. As a relative newbie to synths it's a fun challenge learning the processes behind synthesis and the true joy of this instrument- how to make your own sounds. Truly a landmark instrument.

Much thanks to Rob Amaral for making things right with everything. I recommend this product for anyone who likes rich analog sound. My cats are an audience anytime I go near it. A blast from the past to save the future.
