Does anyone have any experience with these? I bought a rack case a few weeks ago and tt had an Ensoniq MEC installed in it that was 'donated' to me. I've done some basic Googling and other research and can't really find anything on it. I'm mostly interested in selling it. (If I can) What type, if any, value is there in this? I don't know if I have the patience, time or money to get this thing working. It looks like I have to connect it to a computer or something. If anyone has any advice, or comments on these, I'd apprectiate it. Any resale information would be awesome. I've seen somethine very similar on ebay going for about $250 Thanks in advance.
