MR8, J-Station and SB Live

[CEM]

I want to hook up my MR8 (midi out only for master sync) and my J-station (in and out) to my SB live.
I know I can buy a in/out midi cable that plugs into my soundcard - but is there some sort of "Y" cable I can put on it so that I have 2 ins and one out.
Would this setup even work?
Thanx

A y-cable, good one...

You need something that can either merge MIDI messages from two sources into a single stream of messages (a MIDI merger or a MIDI patchbay) or a multiport MIDI interface.
