It includes a built-in joystick for modulation and pitch bend controls, as well as an arpeggiator, sustain and transpose buttons.

It can serve as a USB hub with the use of its two USB ports and is very simple to connect to any computing device since it is class compliant.

Apart from its simple and compact design, several reviewers commented on how sturdy and well made it is. It's very light-weight that they found it convenient to bring around and easily record their ideas on their laptop. In regards to its keybed, the miniature keys are quite responsive and have a good feel to them, making it ideal for sequencing simple synth lines and drum beats. Several users also described the arpeggiator function as 'great'.

Although its joystick is quite functional, some reviewers preferred wheels over this type of design for pitch and modulation control.

The Korg microKEY25 is a portable controller with straightforward and uncomplicated operation. Get it if you want a small MIDI controller to pair with a mobile tablet or laptop setup.
