This news seems to be popping up on various sites across the 'net, it appears to be legit.

The following info and images are from Matrixsynth:

SON OF 4 VOICE's SEMs bring back vintage '70s design ... 100% discrete analog ... absolutly no custom chips.

The audio that screams from an SEM is fat, fine and funky, with a tonal variety unlike any other sound-generating device on this rock we call home. Gang up four of these monsters, and you've got sounds that're thicker than thunder.

SO4V can be used as a 4-voice polyphonic synth or as 4 individual synths under MIDI control. Two SO4Vs can be ganged together to create an 8-voice.

The Polyphonic Voice Control and Programmer section retains all the features of the original Four Voice Programmer and Keyboard control modules, while adding gotta-have-'em goodies like these:
• Two MIDI sync capable LFOs with multiple waveshapes including sample and hold per voice
•Two programmable ADSR envelope generators per voice
• Selectable master tuning (both VCOs or VCO2 only) allows easy detuning for huge unison sounds
• Polyphonic portamento with linear or exponential response
• Noise generator connected to filter input #1
• External audio or A440 tuning reference connected to filter input #2
• Updated output module with mix and pan control for each voice
• Two SO4Vs can be easily connected together - result: eight voices!

I remember that a while back Tom Oberheim had mentioned that he was going to release a new Two Voice SEM... I wonder if that is still going to happen.

To mods:

I've just noticed that @drawtippy has already posted this news before me... is there any way for the threads to be merged?

Unfortunately I don't have a spare US$3,495 at the moment! Also it seems huge! I wonder how much it weighs.

If he made a Two Voice version I would definitely buy it. I've been sitting on the fence about buying one of the new patch panel SEMs or the new SEM PRO...

There is a lot of great new analog stuff in active production these days, it's great! The list is getting longer and longer: This new Four Voice SEM, the standard SEM, Moog Voyager, Little Phatty, Vermona Mono Lancet, Studio Electronics Omega and SE-1X and ATC-X, Future Retro XS, Doepfer Dark Energy, Analog Solutions Semblance and Telemark and Leipzig, Dave Smith Mopho and Prophet 8...

Anyway, I hope this new project is successful for Mr Oberheim.

Indeed it looks really nice.
Just a shame there is no keyboard version, as it would take too much space in my studio to come without a keyboard...

It would be great if he makes an 8 voice polyphonic version with a single interface.
Not sure if the OB-X circuitry is the same as the SEM, but something like that would be great:)

Holy voice tolerances, Batman! I wonder if it will really be encased in tolex/vinyl. All sorts of questions spring to mind, mostly regarding how easy it would be to set up a polyphonic patch similarly on each module. Get two of these and you can be the next Casey Young!

I'm pretty sure that the OB-X uses the same components as the SEM. It was the models after that (OB-Xa, OB-8, Matrix 12, Xpander) that used different designs.

I believe there were some IC's used in the OB-X voice architecture, like the envelopes, for instance. Speaking of that, the Son Of 4 Voice description above says 2 ADSR envelopes per voice, so I'm wondering how the SEM's ADS envelopes fit in.

If you click on the second image above you can see that it appears to have full ADSRs.

The Polyphonic Programmer has ADSRs. That is gonna make it interesting.

It's nice that more flexible lfos were added. Having the S/H and Noise(as in the Mini-Sequencer) will be great - even if there is no lag control for the S/H.

I'm assuming that's 4 banks and not just 4 presets. With a 2-digit display and inc/dec buttons...

I like that he kept the old Tolex look.

Nice...but not a lot of patch points :P .

:thumbleft:

On topic: OMG. Between this and Kronos, there goes my 2011 synth money. I'd love it if Tom did a matching controller.

I don't either, but this will be mine... oh yes, this will be mine.
