Is this a short or is it correct?

Should I be getting any kind of continuity reading between the Vs & Vd pins of J9, J4, or j6 on the Core module?

?

I think you should measure a steady 5 Volts between any Vs (ground) & any Vd (+5V) pins.

Vs & Vd on those pins (J4,6,7,9) are the powersupply for the modules.

I'm measuring without power supplied to the unit to troubleshoot, checking for continuity using my multimeter.  I place one lead to the Vs pin and one to the Vd pin and it shows there is continuity between the two.  I'm not sure if this means anything.  

Electronics is obviously not my strongest subject, but I can solder so I thought I might be able to build this project, maybe I'm in over my head.  I don't see any problems except that I get multiple midi events from my DINS when I should be getting single events ( http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=mios;action=display;num=1078469592;start=15 ), though I've never seen a screenshot of what a working Midibox looks like in midiox when a button is pushed or an encoder rotated.

ah, I did not understand what you meant with 'continuity'. Maybe the caps between Vs & Vd are responsible for that. My multimeter 'beeps' when i look for shortcuts, doesn't do that on my core between Vs & Vd, shows some numbers, but I got no idea wat they mean (i'm no electronics guru) -note: PIC not plugged in.

but anyway, if you do connect power to it (before the rectifier) do you measure 5V between Vs & Vd ?

I think if you have a shortcut, you won't have 5V.

& If you have a steady 5V, I think it's all OK.

goodluck.
