According to the total size of the MIDI keyboard includes all buttons very small, but can still play it amazingly well. The keys are velocity sensitive, which means that depending on how strongly you press a button, the pressure strength used in this case to the generated sound effects (keyword: Velocity Responsivity).
On the far left on the surface of the AKAI LPK 25 are 6 buttons made of soft rubber, which are partially illuminated: ARP ON / OFF, tap tempo, sustain, Program, Octave (up), Octave (down).
The buttons ARP On / Off and Tap Tempo allows you to customize an arpeggiator.
The Sustain button allows you to sustain tones.
With the Program-button presets can be loaded in conjunction with the appropriate keyboard buttons.
The four programmable memory banks, which can be controlled via the included software, are a great touch.
The processing of this MIDI controller, as one is used to AKAI, very good. Everything is stable and for use on the road clearly robust enough. Weighing around 40 grams, it is in addition to the small size and extremely light.
Conclusion:
The handy size of the LPK 25 and the minimum weight make it for use with a laptop at an unbeatable companion for traveling It just fit in your backpack.
At home or in the studio I would not advise you to think of course to a larger MIDI keyboard, but AKAI has deliberately thought to the portable use and everything right in terms of it. With nearly 40 the AKAI LPK 25 is also quite inexpensive.
For those who also want to go hassle free tinker with their songs: a strong buy recommendation.
