The Akai MPK25 was produced in 2009 as a small, portable MIDI keyboard. For more information on what a MIDI keyboard is you can refer to the Music Tools website. The MPK25 was produced for the musician / recording artist who is always on the go. It is fully equipped for music production, yet retains portability.
The Akai MPK25 is a smaller version of the Akai MPK49. The main difference between the two is that the MPK25 has fewer keys than the MPK49. There are multiple Akai keyboards which all have similar features. In order to tell them apart look at the last two numbers in the model name (MPK_ _). Those directly relate to how many keys are on the keyboard.
If you look at the top or rear panel of the keyboard there should be a label identifying which model you have. If those identifiers can't be found then you can refer to Akaipro.com which gives product specifications for each Akai keyboard.
