First, to answer Mr. Unknown, the molex connector is on the motherboard right in front of the memory expansion slot. It's hooked right up to the DOC. Second, since this digitizer is for a Mac, I'm guessing he's got his own A/D in it. If so, then you wouldn't be able to, or even want to hook it up to the DOC's molex connector. If it's got an A/D in it, then why bother using the Ensoniq at all? If it's external (it is), then it won't suffer from being inside of a metal box with a HELL of a lot of RF interference all around it. That right there will improve any digitizing you're gonna do. Hooking it up to the serial port would probably be the best thing to do. As far as software goes, talk to Ian Schmidt. He's the guy who wrote/is writing Audio Zap. Tell him how to talk to it, and he'll add support for it in Audio Zap. I haven't talked to him at all, but I have mailed in my shareware fee, and am eagerly awaiting the latest version of AZ (It's amazing...). I don't have the time now, but over the summer I may look into the dude's digitizer. It all depends on how easy/hard it'll be to write software for it... -Greg T. ------------------------------------------------------------------------ ^ Any resemblance between the above | ARPANet : gt0t+@andrew.cmu.edu ^ ^ views and those of my employer, my | ^ ^ terminal, or the view out my window | ^ ^ are purely coincidental. | Bitnet : R746GT0T@VB ^
