Of course you can connect all three cards.
You will need:
1. joystick <=> midi cable (sound blaster <=> midi) (it is easy to do it yourself if you know electronics or know someone who knows 😉 )
2. midi (minidin) <=> midi cable (din) (scc-1 <=> midi) (you can do this cable yourself)
3. original roland mcb-1 for lapc-1 (lapc-1 <=> midi) (it's not a joystick port!) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem … 8&category=3701

You will also need to set your lapc-1 and scc-1 to different IRQ and address cause they cannot be both on irq=2 and address=330 (unless you want to use 3 computers for that 😉 )

So the "joystick" port requires a special device, huh? I don't happen to have that device, and I don't think I will find one of those sold separately.

I was considering a product called: "midi-over-lan", so that I would eliminate the need for cables, and the extra box for the LAPC-1. Has anyone tried that product? It's devoloped by

Thanks!

half a year ago those mcb-1 things were being sold on ebay in great numbers for 19,99$ each. I think they still should be somewhere.
