The Akai Pro MPK mini is a MIDI keyboard controller. Below is the firmware for the third version of this variably annotated as III or MK3
The links below go directly to the Akai website. The dates I have extracted from the creation date of the exe file.
|Firmware version||Date||Download Windows||Download OSX|
|v1.18 (original)||1 June 2020||Win||Mac|
|v1.26||29 April 2021||Win||Mac|
I can't find any changelog for what might have changed between firmware versions, nor if there were any previous versions available (there does not seem to be earlier versions in the web archive).
Other potentially useful links for the MK3 are:
