Pressing pads on certain areas doubles/triples sounds. Issue

Turntable
Receiver
MPC 2000xl
(optional mixer and a turntable preamp)

Whats the best way of connecting all of these together? I also have a mixer as well. I've been trying all sorts of way of connecting all of these together and I haven't been able to get things rolling (sound).

Using the turntable>mixer>preamp>receiver route is working but when I put my MPC into the mix, well for lack of a better word, hasn't. Any help appreciated, thanks.

Update: I was able to get sound through and working with the switch of some cables, the next issue I have is that I've loaded some drums onto a disk and put it into the drive but the mpc doesn't seem to be reading it. I've tried changing primary load device to floppy as I've read in some other threads but I haven't been able to do so. Also, is the data wheel supposed to be a smooth turn or make clicks as you turn it? I did buy this MPC used off craigslist.. If so is it an easy fix (both floppy disk drive and data wheel). Thanks.

Update 2: Guess the data wheel's a little worn, I have to take the jog wheel off, lift the small knob and turn it to get that click feel. I was able to change primary load device to floppy and access the disks finally. Looked into getting an IDE multicard reader, seems like a good first modification to apply to the 2000xl, any suggestions as to what I should get? I looked at the ones on MPCstuff but they're hella expensive; I've read there are more affordable methods online..

Another note, the OS is at v1.14 and I've been trying to upgrade it but every time I load the 1.20 OS, it says unknown file, what type of file should the OS on the floppy disk be (the file I have is a .bin)? Thanks.

Whats with the small text.

As I've solved my own problems I've just edited my post and re-sized them to correspond that, so my new issues are at the bottom

Thanks for the suggestion. Do you use this reader currently?

Also, as the title now states, I've been running into this minor issue where if I press on a certain area of some of the pads, it doubles or triples the sound as if I was tapping it down that many times. It usually happens on the corners of the pads.

I use the card & ext. reader thru my roomates pc with windows 7,then i go back tp my mpc cf drive internal and load the samples off the card and it works like a charm. Stick to the 8 character / 3 character format of naming the samples cause it will screw up the sound (file). The doubling of sound is normal as i have seen that on most of my friends MPCs at one point or another. If it gets to the point where it seems to be maybe the pad sensors are at fault, you can easily uncase your MPC and get to the pads and blow out the dirt or particles using some pressurized air,that did the trick for mine when i had that problem. But just so you know,that is normal,the pad sensors are very delicate and pickup on your finger bouncing on the pad when you hit it hard enough. Im sure you may notice that it will double only when you hit the pads hard enough. If that is not the case then you will need to cleanout the dust/dirt particles in the pad sensor area like i explained before. Try using FULL LEVEL and just touch the pad,you will notice it will not double up . Let me know whats up,peace.
