What:
Tom Oberheim has been developing electroni products for musicians for over 35 years. He invented a number of innovative electronic music products, including: the first polyphonic synthesizer, the first phase shifter and ring modulator for the performing musician, the first completely programmable music sythesizer, and the first electronic music system that incorporated a synchronized music synthesizer, digital sequencer and digital drummachine. On June 3rd we welcome you to come listen and learn about music, inspiration and life through Tom Oberheim's eyes.

When:
June 03, 2009
19:00 - 21:00 EST

Thanks for the link, it seems a really interesting interview.

Will the announcement of the new synth be displayed live in their website too?

The first completely programmable music sythesizer? which model?
Was the first programmable synthesizer is not the PPG 360?

:lol:

you obviously haven't watched a Redbull Music Academy interview. just assume they also wrote that he invented the screwdriver and cured polio and you'll enjoy the experience more.

Thank you, Mr. Oberheim. =D> \:D/ Two(more), please.

Discussing sound(and price) is pointless, to me. Mainly because, as others have eluded to(xpander,0000 - you guys are such teases! :) ), of what is on the inside. Besides, of all these modern re-releases of oldies, I expect this one to sound 100% like the original - for the same reason the insides are the hidden gem - design. Look at this:
Image
Anything look too hard to find these days? Not to me, and I'm an electronics idiot.
I took this Monday night when, on a whim, I decided to switch my two mod jacks(the 2 gray wires to the right) back to where I normally have them. In the pic, they are going the External Modulation In on each oscillator. Now, take a look at all(15, minus power in the lower center) the molex connectors. Every pin has a function. Notice they are color coded. They are also letter-coded. For instance, the gray molex(letter H) in the upper left goes to the filter. The pins are: H1 - CV in1, H2 - CV in2, H3 - Ext Mod in. That's three filter inputs in one molex. If you want to find these on the schematics just look for H1-3. Freakin' beautiful. There are 36 pins(and 9 ground pins) that can be brought out to jacks without ever having to get a soldering iron anywhere near the circuit boards. If you want the full list, check out The Analog Cottage. He gives you the map and the key, not to mention calibration and patching recommendations.

Leaving an SEM stock feels almost criminal, to me. These just are begging to be modded. They're just waiting for it, quietly mocking you every moment you don't. My friend described it best when he called it a blank slate. Tom made it super easy to modularize but left how you wanted to mod it up to you. That's actually the hardest part. Figuring out what you want and then designing your patch panel, that's the hard part. The wiring is merely tedious and getting inside the SEMs is not that big a deal. I don't like to open synths unless I have to, except the TVS. Switching those jacks and taking pics took about 15 minutes and a screwdriver.
Image
This pin(out of focus in the center) is going to H1. See, you don't even need the molex connector. Just the pin.
Most CV I/Os are 1 pin. Now, here's the other big thing. Since the SEM based synths are basically a bunch of modules, guess how they are connected.
Image
Yep, more molex. This is the Mini-Sequencer and my second mod jack went back to the white molex(H1- ironically), External Clock In. So, when xpander says there will be more, I take this to mean we will see a new Mini-Seq, Polyphonic Programmer, etc, and maybe totally new modules.

If anyone would like to hear some(15 or so) SEM sounds and sequences, check these out(10mg mp3). These were mostly made about two years ago. Most are Techno-ish patterns. All sequences are the Mini-Seq except the one at 2:24. This one I did Monday to test that the filter jack was ok. It was sequenced in Sonar and the filter is modded by a tempo-synced Tri LFO from the Kenton. This also the only one I EQ'ed. There is delay/reverb on many, though.
This one(6mg mp3) is just a bass tweak sequence. There is a full range filter sweep at the beginning. This is the first sequence where I used the Seq2 Clock Mod(pull the Clock knob up.) This allows you to set the length of steps for Seq1 with Seq2. Nothing too special.

Also, search for reWire's thread about the power of two SEMs. Great audio demos, if they're still up.

If you are wanting to go modular and feel intimidated, one SEM might be a great start. No single synth has taught me about the "other side" of analogs. And, if you want an SEM, I highly recommend the Mini-Seq if they make it. It's not just a sequencer. So much more. Mine is possessed. I though I would never use it. Twenty minutes after I got my TVS, I got up, called a guitarist friend and told him "I think this thing just called me a b***h!" you know, the S/H is going " bee, bah,boh,...b***h..." Give the sequencer pitch/time info and the S/H can play a mean solo for you just with the filter. Just sit back and wave your hands in the air. I have one recording the guitarist friend still can't believe is a all "machine".
Well, the only bad thing I can see, so far, is that I can't feel "special" anymore :cussing: :cry: ... :D Oh, well.

Yeah, the three CA3080 ICs used in the VCF and VCA, they are out of production.

What about the NTE996? Any experience with it as a replacement?

It's a probably a relabeled CA3080. NTE does not produce anything, they just rebadge and resell old parts at a 300% markup. There are plenty of modern chips that have similar functionality. He should move forward with a modernized discrete design. There are plenty of excellent modern IC's which could be put to very good use in the right hands.

Looks great! Price will apparently be "under 1k"... tho I imagine pretty close to it as I thought... Wonder if there will be deals for more than one voice.
Do you even post on vse bro?

if its fully discrete like the original, and no SMD.. and under a grand.. thats VERY tempting, considering how expensive the original SEMs got in recent year..
