This is a pretty cool firmware update. You can now create and upload your own chord progressions.
The standalone MPC Live or X will now load user progressions - To use your progressions in the standalone MPC X or Live, on your preferred storage device (MPC internal SATA drive, SD card or USB Flash drive) create a folder called Progressions at the root level. Next, on your desktop computer navigate to your user progressions directory Mac ~/Library/Application Support/Akai/MPC/Progressions, Windows C:\ProgramData\Akai\MPC\Progressions and copy your user progressions into the Progressions folder on your preferred storage device. Lastly, in standalone mode, connect your storage device to your MPC Live or X, when you go to Pad Perform > Progressions your MPC will read the user progressions in your Progressions folder and add them to the Progressions list.
