As promised, I have scanned and uploaded the Oberheim OB-Xa "Programmed Patches" book to my website at this address:

http://www.electrongate.com/obfiles/OB-Xa/patchbook.html

Enjoy, and let me know if you find any broken links or mistakes.

Thanks,
Paul White

I can think of a couple of possibilities:

1. Bad patch tape. Try programming patch A3 manually (see patch

sheet here http://www.electron gate.com/ obfiles/OB- Xa_patch_ A3.jpg )

and see if it works OK.

2. Bad or missing RAM chip. Try storing a working patch in the CD

and ACD banks and see if they stick.

Good luck.
