When the buttons/knobs are changed on the front panel, all of this info is echoed over midi. But the cmds use sysex, which is slow. If you connect the midi out of Xpander 1 to the Midi in of Xpander 2

I know you say "short of hunting down a Matrix-12", but honestly if you can live without the CV jacks, the M12 is the way to go if you want extra voices. The benefit of going the M12 route rather than

I recently got an Xpander, and although it's incredibly deep, six voices isn't much to play with. Is there a way to pair up two Xpanders (short of hunting down a Matrix-12)? Or even more than two?

Thanks Karl. This would be madness on an iPod, but would be great for an iPad.

Hi All, This?is sure tempting to me. Look to the?left to find the different synths.? http://www.icontrolmididesign.com/ Best Karl Schmeer

cool idea I'll try it. Like I say its no big deal just that my xpander is right next to me and I can hear it through my headphones...

Hi, Same issue, I put a piece of Styrofoam between the transformer and the chassis, this reduced the noise significantly. Greg

I have it since I buyed it new when it came out. Its not in the audio path. So what ? A custom built toroidal transformer helps if you want to make that investment. Am 20.02.2011 12:22, schrieb

Hi yes I have the same issue. Not too bothersome but it seems to get louder over time...No biggy just a little annoying. Nick

Hi. I've an Xpander that works good, but there is some humming noise from the PSU. A little research on the net revealed that this is quite common to the Xpanders. Is there anything I can do to remove

I have both in stock at the moment the way. :) Doug, synthparts.com

hello all, thanks so much for your help. so i disconnected the rear harness of the TOP voice board that connects to the main processor board, and the machine boots. it reads: "voice 1 processor

I don't remember what the B indicates, but the trailing P indicates Plastic packaging ( I think) I'm not 100% sure about that. Better refer to a hardware person who is more up to

Thanks so much Tony! so the M12 processors number is HD68B09P. assume thats a 6809, NOT 6809E? that jameco link, its a drop-in replacement for all 3 processors? LAST question: are there any other IC's

Well, thats news !!! thx for info Am 16.02.2011 19:33, schrieb Tony Cappellini:

There are 3 in the Matrix 12, because it has 2 voice boards + the main board. I don't remember if the 6809 in the Xpander/Matrix is the 6809 or 6809E (External clock). These are commercially available

There are 2 processors in the Xpandr/Matrix-12. If one of these fails and you need a replacement,- your only chance is to buy a Matrix-1000 used. Is the same processor. Am 16.02.2011 18:37, schrieb

the voltage SHOULD be +55vdc(+/-4v, according to SM); it reads 60.2. also, last night, i removed and reseated the 4053 and two tl081's on the voice board(related to SM calibration, so i thought i'd
