To upgrade your Oberheim Matrix to the latest firmware fully compatible with the Matrix Ctrlr, you need to remove a big chipset and insert a new one furnished by Alpes Machines or someone else.
That means opening the synth so turn off the synth and remove AC outlet first to avoid any problem to your health.

Notice the EPROM has a notch to fit the footprint on the PCB and pins order : locate the orientation first and keep it in your mind for later :
Oberheim Matrix 1000 :
- open the rack,
- locate the old EPROM,
- remove it,
- insert the new one
- and then close the rack :
- open the keyboard (2×3 screws on the sides)
- locate the old EPROM
- pull it out
- insert the new EPROM
- close the lid
That was easy 😉
Now enjoy all the power of those new firmwares developed by Tauntek
NOTA : the EPROMs are available in the shop.
Please consider upgrading your Matrix 1000 circuit if the old EPROM is 1.03
