Midi chain question

Yo, all of my beats are done on a MPC2000xl and a Motif, using the MPC to sequence on.... the otha day ma boy brought ova his RS7000 and i plugged did it Midi Out-Rs7000 to Midi in B-MPC, and Midi in RS7000 to Midi out b - MPC..........then i got the Motif hooked up the same way, just through the otha ports on the MPC.... my mp and motif stay hooked up, but when i hooked up the plugs to the Rs7000, all i got was like this loud buzzing... whassup with that?

That doesn't sound like a midi issue. What happen's when you unplug the midi cables while it's buzzin' like that?

I agree with mrfaia, this sounds like the gain is too high on the RS or the mixer.

When I pulled the Midi Cables out, the buzzing stopped, and we actually made a beat on the RS still hooked up to the mixer, so it can't be an audio problem.....

bboutit, what do you think; a possible bad ground between the equipment?
I'd try plugging the equipment in to differrent outlets next. Also, which piece of equipment is the buzz coming from? Does it come from the piece your introducing to your setup or from your gear? What happens when you kill the volume on each individual gear? I'm just trying to get a better understanding of what's happenin' since I'm not there personnally....

It comes from tha new piece.... And it wasn't a faulty piece of equipment, because when I plugged in ma boys E-mu, the same thing happened........ i'm thinking maybe there is a faulty port on my MP?

I would try disconnecting your unit (leaving just the E-mu) and if it still buzzes, then try plugging the e-mu into the port your sound module was plugged into (port A) without having anything in port B. If there's no buzz in A but only in B (and nothing else is plugged in) that would single out the port. At that point, I would then try plugging in your sound module into B with nothing in A to see what happens.

I agree with mrfaia on above.

I would start from the ground up, have you tried using the cables from A to B to see if that makes a difference. I don't understand how sound could be coming from using midi, but who knows. Possible grounding in the cable or the cable is bad and causing interference.

I've tried it... It's only when i plug it in to B that it makes the noise

Even with your own sound module? Damn... I hate to say it but that don't sound good to me...

Can you turn off your mixer, plug your headphones into the sound module that's on B and see if you still get the buzz.

If you do; Try taking just your MPC, sound module and midi controller to another outlet. Plug the sound module into B and plug your head phones in the sound module and see if you can play anything without a buzz.
