Oberheim OB-SX Part 1

YouTube Uploaded by PeteMOBie1 on Dec 7, 2010

"Introduction to the OB-SX, a very underated synth that is a hybrid between the OB-X and OB-Xa. The OB-SX shares the voice architecture of the OB-X, but uses the discreet CEM chips later found on the OB-Xa. The OB-SX first appeared in 1980 as a preset/variable version of the OB-X.

A short demo demo of the brass sounds from A1, B1 and C1, using the variable controls. If the sounds in your OB-SX are different to mine, you could have a rare machine, as OB-X users could send in a tape of their favourite sounds to be burned into the OB-SX EPROMs. Also mine will have slightly different tunnings and voice calibrations to yours.

More vids will follow, so I hope this gives you an idea of the sounds and capabilities of this great "little" synth.
This was recorded using the inbuilt mics on the video camera, so please don't expect pristine 24 bit audio ... not yet anyway. Also this is unscripted.

Note that the key clattering is normal on machines of this vintage, mine is from1982.
Cheers

Oberheim OB-SX Part 2

"Part 2 of Pete's expo on the OB-SX.
Using only the A1 Brass Ensemble program as a starting point and the 7 variable controls on the front panel, a variety of sounds can be coaxed out of the OB-SX with considerable ease. The OB-SX might be your best bet it you cannot get your hands on an OB-Xa or OB-X."

Note this one has the older grey style similar to the OB-X. The OB-SX is a massive sounding synth, possibly more-so than the OB-Xa, but it does have limited controls and is more of a preset OB-X. The voice boards between the SX and Xa are different. Not sure about the X. If anyone knows feel free to comment.
