The technical review of the Prophet 12 Keyboard in November 2013’s Sound on Sound is pretty much exactly right (at that firmware revision) and is a good and true assessment of the machine I had delivered.

Some technicals you don’t get elsewhere. I’ve crawled all over this synth with an RME Digicheck on the outputs. Mine has a consistent noise floor of -83dB, which is, by way of comparison, 2dB above the noise floor on a Manley Massive Passive. Looking inside, there’s 6x24179 4th gen SHARCs running the digital oscillator block (roughly 12 UAD-2 3rd gen cores).

It’s DACed into analog and stays that way all the way to the TRS outs. There are optional effect sends back into the Oscillator block, but it is as analog sounding as you can get without genuinely analog Oscillators, but then it holds tuning across chords better than any analog.

The synth itself is almost perfect. There’s not a single cut corner, no economies, no compromises. It is engineered beautifully and I don’t just mean the build quality, I mean the engineering. It’s a player’s synth and responds seductively to the slightest touch. My SN is just below 3000, so I don’t think there are that many of them out there. Oh well, what a pity, never mind.

But this synth does have some severe problems. The first is that when you switch it on, you’re off with the fairies for hours on end, and sometimes forget to eat. The other big problem is that toe rag almost famous musicians, who haven’t bothered to keep in touch with you maybe even for years, suddenly phone you up and ask to come around and play with it.

Anyone who tells you this synth has a ‘sound’ is looking into the mirror of their own sound design. Its range is monumental. It makes no concessions to fashion or genre and is a total chameleon. I’ve heard Novachords, Moogs, Waldorfs and Yam DXes in this synth (it now does 4-op linear FM). When I unboxed it, every single knob had been set to 0%, the volume being vertical at 50%. It’s a class act. It’s like driving an Aston Martin.

What famous synth is the Prophet 12 most like? It’s most like a Prophet 12. And it sounds incredible. Creme tangerine and Montelimart. A ginger sling with a pineapple heart. A coffee dessert, yes you know it's Good News. But you'll have to have them all pulled out after the Savoy truffle.

It’s like standing on the beach down at Surf City the first time you visit California and see the Pacific for the first time. That vast empty nothingness. There are so many people who blether on about creaminess and phatness and whatever tawdry scraps of fantasy they bring to synthesis. Imagine what it must have been like, for the lucky chosen few, to have been there at the dawn of it all. To stand there with a machine when its streets had no names. When the straight-jackets of genre and endless masturbatory genuflection to the sound of the past had not yet closed the minds of a generation of musicians. The shock of the new. That vast empty nothingness.


I wonder if that's my one.

This review has several problems.

1) It makes me want to buy one
2) see number 1

I have a module. It's a wonderful instrument. I also have a Pro 2, which is just as wonderful. Yes, I have lost many hours of my life down the DSI rabbit hole...

Post

Yeah sounds stunning. Pretty juicy.
What's the desktop version like? Same specs?
Looks a tad "SQ-1", with the buttons and serious lack of knobs.

I bought a Tempest instead, gonna try to develop a live set with just the Tempest and my Bass Station II.
I think if i get another DSI it'll be the OB-6. Love those silky SEM sounds.
Plus there's a fair bit of history in these 2 DSI collaborations. Call me sentimental.
Just wish Dave and Don had've collaborated too... probably wouldn't have been able to afford THAT one though :P

Desktop version is great, but it's missing the pressure sensitive sliders. That's the biggest omission in my view. Everything else is pretty intuitive and I don't really miss the specific knobs since the interface is so damn slick. The sound engine is identical.

Yeah, the OB6 sounds VERY lovely, but personally I'd miss the extensive modulation of the P12 and the Pro-2. What makes these synths so awesome is not their sound so much as how deep they can go... four oscillators, loads of cool digital and VA waves with waveshaping, four LFO's, 4 envelopes (5 on the Pro-2) extensive mod matrix, linear FM on the Prophet 12, 16 track mod sequencer on the Pro-2, the Pro-2's awesome filter set up (one Prophet 5 style 4 pole LPF and one SEM style multimode filter with completely configurable routing) 4 delay lines (BBD on Pro-2), dual layers on P12 with split or stack.. Aaaahhhhh, just pure fun. I'm totally in love with them both!

Problem is... whenever I sit down in front of my gear, I fall into the rabbit hole and make sounds instead of making songs.

oh GREAT :roll: now you've got me eyeing off the Pro-2 :D
I didn't really look at it initially just cos it doesn't have a desktop module version.
sounds good.
but i think i'd still prefer an OB-1 :P
with MIDI :scared:

the desktop DSI Prophet 12 must be quite similar to program to the Oberheim Expander then?
I own an ESQ-1, so i've served my time on the 'single encoder' trip, but that said, it's probably still faster than a mouse.
i actually spent most of yesterday on the Vintage Synth Explorer... pining through all the Oberheims like a total lost cause... man, they're just SO good. I've personally never heard an analog i'd like more than many of these machines. And that's just from crappy youtube videos :P
i feel like Wayne in Wayne's World, with the strat (was it)... "Oh yes, it will be mine"... Matrix 12 :P
gotta dream ;)


got to dream

The main PCB in the Keyboard P12 is >exactly< the same size as the Module unit. It is I think the same synth is a different dress.

except for the missing sliders..

lax on the knobbage

For a digital synth its awesome.

it's a hybrid

It is indeed a hybrid.

Custom DSI Curtis CEM analog filters, 12 of them. Six 4th gen SHARC chips below them.

it's a great big slab of hybrid awesomeness! :love: :love: :love:

this seemed apt for some reason?... since were talking about boobs and all...

Congrats, love my P12. I recently released an intelligent Patch creator / randomizer that I use for sound design, you might be interested: https://itunes.apple.com/us/app/oracle- ... 1198283877
