I Know This My Sound Like A Dumb Question But...

I used to deal with hardware gear and midi alot when i first started making music (about 15yrs ago). so for the past few yrs ive been on the computer side of it. now ive somewhat switch back to hardware (keyboards, mpc 2000xl, roland rack sampler, etc..) and guess WHAT? im not sure anymore on how to connect it all to my mpc via midi. i drew a complete BLANK last night and felt so stupid.

i got the 1 keyboard to respond well with the mpc and that was through a midi "loop" sorta speak. it was basic: midi out of the mpc to the midi in on the synth and midi out of the synth to the midi in of the mpc but i still have another synth and my roland sampler out of the mix and i tried every connection possible!

can somebody explain to me whats the proper connection to make all this work.
here is my gear:

MPC 2000xl
Korg Wavestation Synth
Yamaha CS1X Synth
Roland S-760 Rack Sampler

But once the gear is connected to the MPC, I want to use the transport from my Tascam FW-1082 Control surface to start and stop the MPC for tracking purposes to Logic. If i can just get the right midi connections going with my gear to the mpc i think i will be fine from there. THANKS!

for just the gear. leave the keyboard hooked up as is. then go from out "b" to the other synth in. and from the through port of synth "b" to the in on the sampler. then to use it all you set the track your on to "midi" and whatever chanel you want to control. watch this vid to get the basic's
