MM pickup help needed!

[SantiagoGT15]

Well recently i purchased a ray34 and well it was dead quiet until I plugged it unto an m-audio interface, suddenly I get all this hum and well noise (didn't have it on my amp), I figured out that by touching either the cable at the metal area, the control plate or any knob, or the bridge cancelled all that noise, but I thought MM pickups were silent , so I headed here , any tips any help on how to get rid of all that noise and hum?
I really need help , I've heard some things about shielding the pickups but I don't know if that's the issue D: I need help ....I 'm counting on you....

Can we assume that this interface is quiet with other basses?
(not trying to be mean spirited but rather to eliminate possibilities)

Probably it's a grounding issue related to the computer.
If it's a laptop can you try again with disconnecting it's charger?

I did try both , still that buzz and hum , today I tried it in a bigger rig (ampeg Svt-3 pro), I also checked all the pots and wiring, I checked also the string and pickup height but still not a clue of where that sound comes from ... although the bigger rig reduces the noise , I still get an audible noise which also is considerably reduced by rolling down the mid knob on the bass, I changed and double checked strings , batteries and even the amp :C

Is it possible maybe that the pickup is a failed one? , I read that humbuckers cancel out the noise because they have 2 coils , so if I get noise is it possible that the pickup is failing and i am getting only a single coil?
