The Akai LPK25 is a great beginners MIDI keyboard for those of us who are looking for a set of keys that won’t break the bank. This lightweight and portable MIDI controller is great for the on-the-go music producer, as well as live performances with the built in arpeggiator function. Plug-and-play connectivity make for an easy setup. I’ve personally owned and used the LPK25 to produce music for over a year now with no reliability issues, which seems to be a real concern for other buyers. The main problem people are having is with the USB connector. I don’t move it around or unplug it too much, so this may help prevent damage to the connector.

For intermediate or advanced musicians, namely those who are skilled with the piano, my suggestion is to look elsewhere for a larger weighted or semi-weighted (and more expensive) keyboard controller such as the Nektar IMPACT LX88+.

How It Stacks Up

The Akai LPK25 faces stiff competition from comparable 25-key MIDI keyboard controllers such as the Korg microKey25, M-Audio Oxygen25 MKVNektar IMPACT LX25+, and the successor to the immensely popular Akai MPK Mini MKII, the Akai MPK Mini MKIII. It’s worth mentioning that each of these competitors offer other additional features such as launchpad buttons, faders, and knobs, and also come with a heftier price tag. For a simple set of keys, I think the LPK25 is worth it.

OK, let’s dig in to the details!

Akai LPK25 Review of Pros & Cons


  • Lightweight and highly portable
  • The octave shift buttons are convenient
  • The controller is USB powered, so no external power supply is required
  • Easy plug-and-play setup for most DAWs
  • Arp feature is a lot of fun and easy to pick up on
  • Compatible with many big-name DAWs such as FL Studio, Ableton Live, Pro Tools, Cubase, and more.


  • The keys are overly springy, non-weighted, and may take getting used to for piano players.
  • Too small for anyone wanting to record live piano sessions.
  • USB connection port on the keyboard itself is weak and prone to loosening and breaking. If you plan on moving the keyboard around a lot, I suggest unplugging the USB cable each and every time
