Technical questions for the MPC2000xl and the MPC2000

It just sounds really wacky.
What we are trying to determine is, is this an audio problem or a pad problem?

For the pads, you want to get both visual and audible confirmation that they are not having an effect. This is why homedude said to go into step edit mode and hit a pad. Does it input a note? You will be able to see it if it does.

The way to check the audio is to bypass the pads...go into trim screen and use the F6 button (PLAY X) to see if you get any sound. Forgive me if that's a little off...I've never used a 2k and it might be different from XL. You also might have already done this by trying to play a sequence...but just trying to eliminate as many variables as possible.

Having said that, try all these test with no zip drive, maybe even try no memory. Eliminate as much as possible.

The point for this relentless double checking is that the pads + audio shouldn't really be related. It is more unlikely that both things would go out at the same time. Still, it is possible, but just trying to be 100% accurate on the exact symptoms.

Maybe if you had some detailed pics, somebody else who has taken apart a 2k might notice something horribly wrong? Maybe dude plugged your scsi into your pads, I don't know, just sayin, the issue sounds that weird.

Indeed. Exactly.

It sounds extremely weird that it was working fine and then both things could go wrong.

What Noggin said about the pads maybe being plugged into the wrong spot sounds like a good idea. Look around there. And definitely right on the $ with the whole unplug the drive and the memory as well. If you break the whole system down into its respective components it will be easier to solve.

And yes. If you open it up again take some pics.

EDIT

I can't stress enough that your 5 senses are your best tools. I have looked at a piece of busted gear for days seeing nothing only to turn it over one day and have a part with a broken lead, misconnected wire, or a burn mark just basically stand up and dance for me. Persevere. Keep looking at it. Don't touch it as much as look and look and look. Something will pop out. It really sounds like the issue is a bad connection.

I believe that its a problem with the -12 power supply and the fault sould be in the big resistor near where the power cable goes in the main board from the psu..
Mine had that fault too..Just replaced the resistor (used as a fuse there) and everything was perfect then..!
I believe that your mpc cant sample too as it is (was, cause its an really old thread) now..!

The output needed to come out as it was mashing up the OS!
think the first engineer effd it


You mean the AD/DA output board was effd and the solution was to change it?
