Xpantastic!

Hi guys,

Do any of you have this expansion mentioned below?
This would awesome, since you very quickly run out of memory with 
these very programmable beasts.

Memory Expansion
Eric Rehl reports: "Since I don't carry a computer around with me 
when I go to different studios, it became important to me to have a 
lot more patches available inside the Matrix-12 than the 100 singles 
and 100 multis we are all used to. So pay attention, everyone, I have 
a solution which I would like to share. 

"My friend Joe Weitekamp, at dBm Electronics here in New York, has 
devised a modification that quadruples RAM storage in the Matrix-12! 
It will also hold patches in the edit buffer and will let you 
transfer them between the four banks of available storage space. He 
used a momentary push button switch which cycles between the banks, 
and installed a set of four LEDs to let you know which bank you are 
in. You can also use all the normal patch storage schemes now 
available (cassette and MIDI). It cost me $450, but could be 
different now; contact him for details. Two caveats: it hasn't been 
tried yet on an Xpander (although I called and asked him about that, 
and he said he felt it would be easily accomplished) and he wasn't 
sure whether he would offer it as a kit or require that the 
instrument be sent to NYC for him to do it himself.

Joe does other custom work that may be of interest, including an 
amazing MIDI mod for the Memorymoog. He's very busy, so please don't 
call just to chat. If you're interested in his work, call or write: 
Joe Weitekamp, dBm Electronics, 124 W. 19th St. New York, NY 10011 
ph. (212) 645-2626

DISCLAIMER: Neither I nor the XUG will take responsibility for any 
non-factory alteration of an Xpander or Matrix-12. Joe's reputation 
is good, and I'm thinking of letting him hotrod one or both of my 
Xpanders, but before you go sending your gear off to him, remember: 
you'll void your warranty, and may make it difficult for other 
Oberheim repair places to service your unit. Talk to Joe about the 
ups and downs of this operation before you make a decision, and if 
you decide to it, let us know how it turns out!"
