Oberheim Expander / OB-Xpander?

via ConcreteCancer on the forum:
"Okay, my dad is trying to remember an Oberheim product that looked like the OB-X and was called an OB-Xpander.

Anyone have any info on these pups? They are mentioned on a few websites but i can't seem to find anything solid or pictures."

Note this is obviously not the Xpander. I seem to recall mention of the "Expander" on various synth lists and forumns in the past. I did a quick search in the archives here and on Google image search but came up dry. Anyone recall this one and/or know where we can find an image of one?

Update:

This one in via Vincent. Click here (note this is an affiliate link and supports the site, if you prefer a non affiliate link, click here), wait for the Amazon book reader to come up and then in the left search box, search for OB-Xpander. Click on the first link that starts with "page 170." In the resulting page, scroll down and you will see it.

The following is a question from Vincent. If anyone knows, feel free to comment:
"I was a Music Synthesis student at Berklee College of Music in Boston, MA in the late '80s, and I'm willing to bet that this photo was taken in one of their synth labs, as prototypes occasionally made their way past faculty and students for evaluation. '82 was 4 years before my time, but I'd swear it's from a Berklee synth lab. Can anybody confirm? I have an OB-8, rev B5 with MIDI; cutting it down to look like this in an 'OB-Xpander' format could be very practical, in 2010"

  1. There was at least one "Expander" made, it was pictured in Mark Vail's book IIRC and I think the picture may have been shot at the Berklee (Mass.) synth lab, for what it's worth. The unit looked like an OB-8 without a keyboard...find that picture, and check it out.

  2. I confirm! There was a keyboardless version of the big OB-8. It was in the "Oberheim music fair system" with the DSX Sequencer and the DMX Drum Machine.

  3. Yo can see in this pic that Jack Secret (RUSH's on stage keyboard tech) and this keyboardless OB-8. Jack Secret said that he did this along with a lot of other mod's for RUSH's set up.

    Here's the pic from another site...

  4. Of course, this was back in the day RUSH used a lot of synths.... *sigh* I miss that.

  5. Actually it was neither the 8-voice nor the OBX.

    What you´re thinking of is a prototype unit called. OB Xpander.

    The specs are a bit hard to confirm as it never went into production.

    But it looked like an OBX-A with no keyboard and supposedly was a 4 voice multitimbral module.
