Akai MPC 1000 encoder replacement

I found a blue Akai MPC1000 for cheap and i am in the process of restoring it.

The blue, old style MPC1000 has a few issues: old style pads behave erratically and the encoder has just seen better days.

The old encoder vs new encoder: the old plastic body one is impossible to find, and the new metal encoder requires you to mod the pcb to be usable.

I have installed JJOSXL on my Akai MPC1000.

The form factor differs slightly in these two encoders.. more on that later

Disassemble the Akai MPC.

Right side, front PCB. Here be most of the control buttons and encoder.

Encoder solder side-bottom of PCB

Using a desoldering braid or pump, suck the solder and remove the encoder

Solder in the new one, using great care

Make sure the new encoder is flush on the pcb (slight physical difference with the old plastic one).

The pins will look like this.

Make sure the encoder’s body is being pushed all the way down on all sides when soldering it in.

Like so. Flush on the board.

Turn the board around and CUT these tracks. There has to be no connection between the two ends. Check using your multimeter set to the buzz function.

Now using some solid core wire, make these connections:

Check if the bridges have been successfully implemented using the buzz feature on your multimeter, then reassemble.

Switch your Akai MPC on, and press MODE+the OTHER pad.

Access to the ENCODER menu and select NEW TYPE.
