Today Marks the 10th Anniversary of the Sequential Oberheim OB-6



Andrew McGowan, pictured here with Tom Oberheim, wrote in to let us know today is the 10th Anniversary of the Sequential OB-6. Andrew was a product designer at DSI/Sequential and worked with Tom Oberheim on the OB-6.

You can find a write-up on some the development of the OB-6 as well as the Prophet-6 on his website, https://www.smartbombdesign.com.

A couple of excerpts:

"I was sitting in my office at Seer Systems one day in 1997 or thereabouts when the phone on my desk rang. It was Dave Smith calling from his home. 'I’ve been talking to Tom Oberheim. He’s between jobs and wants to learn about software synths, so I asked him if he wanted to write the Reality operation manual. Can you get him set up and manage that?' I knew who Tom was, of course, but I had never met him, and now Dave was asking me to be his manager. I had no reason to believe that Tom was anything other than the warm, bright, and kind person that I now know he is, but the idea that I would be managing him made me deeply uncomfortable.

Seer Systems was in the process of developing Reality, which is generally considered to be the first 'professional' software synthesizer, though I’m not certain what makes one synthesizer professional and another not."

[Side note: Propellerheads Rebirth was also released in 1997, however the demo version was released in October 1996. A bit like The Damned vs. Sex Pistols for those in the know!]



And [thought this was funny]:

"Those Fucking Lines

Tom and I had talked about synths over the years and, on several occasions, he remarked how often people asked him to remake the OB-X, perhaps because not many were made. Or maybe Rush/Tom Sawyer? I don’t know. What little I did know about the OB-X was that it had a (low-pass only) SEM filter, and we had already made a synth with an SEM filter in it. And our hardware engineer Tony Karavidas had worked at Oberheim and owned multiple Oberheim synths. I also felt very strongly that if we were going to make two poly synths that were essentially the same except for the filter, the 2-pole, SEM state-variable filter would be complementary to the Prophet-6’s 4-pole, OTA low-pass filter.

Tom’s wish list was short. He didn’t want the Prophet-6’s analog distortion. And he wanted the OB-Xa’s blue lines."

[P.S. I still own an OB-6 desktop and it's one of my most cherished synths. There is something organic about it. The demos I've heard of Sequential's new FOURM have that about them. I have enough synths as it is but the FOURM is very, very tempting for this particular reason.]

Mother Lode synth meetup #3 Pics



A few pics from the latest Mother Lode Synth Meetup sent my way via Brian Comnes.

You can find the full set here.

That's Brian Comnes with the Buchla Music Easel.

Below is Mark Vail, author of Vintage Synthesizers and The Synthesizer with the Beetlecrab Tempura.

Small group shot further below. Be sure to see the full set for more.

P.S. Brian also had an iPad with the following to say: "Had fun showing Textquencer app , it converts text to midi notes, quite the sequencer, the letter A is the root note. I used our mailing list as the source text 😁. It’s also good with foreign languages with a lot of vowels like Hawaiian or Native American sources.

I also think Igor Vasiliev’s GLITCHSCAPER app for percussion is great, certainly not an 808/909 cliche"

Also: "in that picture I did an a/b comparison between the $5k Easel and the $200 KORG [Volca] modular with midi hack, and IMHO the KORG did pretty good😛"

See the Mother Lode label for additional posts.

The Stylosette Keys by Dubreq

"Dubreq released the Stylosette last year but I'm just now getting around to buying one. I'm not sure why it took me so long but here's a quick overview of the Sytlosette Keys and what it can do.

The Stylosette is the latest addition to our Pocket-sized Analog synthesizer range. It’s a monophonic mini analog synth that looks like a cassette and comes in a cool retro cassette storage case for batteries, clips, a screwdriver and cables, which are all included. It also has a built-in speaker, aux out, and an expansion port.

Use the crocodile clips provided to trigger sounds using conductive objects such as fruits, vegetables, or spoons! The Stylosette has a 13-key touch-sensitive keyboard and is played by sliding your finger along the touch-sensitive metal surface, so no need for a Stylus.

Each segment on the synthesizer keyboard plays a different note, so you can create rich, dynamic music with delay effects, vibrato, and a three-octave range.

Change the speed, depth, and delay with the screwdriver accessory to customize your sound. Even connect to another Stylosette. Buzz, twist, and warp every note in the palm of your hand – anywhere.

It’s an excellent gift for both musicians and beginners alike. All you need to do is insert batteries, turn it on, touch the keypad, and make some noise!

Check with dealers on the right for availability.


Stylophonic Fun

"This work uses a runaway noise generator from Hikari Instruments / Duos as the main source. This extreme signal was passed through the external input of the legendary 1970s Yamaha CS-10, and then thoroughly deconstructed and reconstructed using filter modulation.

The unpredictable chaos of the Duos and the sharp yet sticky analog filter of the CS-10 resonate with each other, creating a dry, tense acoustic space reminiscent of the 'Dead Zone' suggested by the title.
The critical point of electricity. Listen to the texture."
