Gearank Recommendation

The X3 mini had a long run on our recommended list for MIDI Keyboards Under $100 lasting from September 2018 until July 2022 when it was removed due to being out-ranked by other keyboards.


The Midiplus X3 mini has a semi-weighted keybed with 37 keys, which is quite good compared to what others are offering.

Another cool feature of this MIDI controller is its capacitive touch sensors for that let you control pitch and modulation.

It also has four customizable knobs and 6 customizable buttons that you can assign to specific parameters on your virtual instrument or DAW.

And it comes with 1 old school 5-Pin MIDI out for use with hardware MIDI devices.

For those with limited budgets that want an affordable MIDI keyboard with more than 25 keys, do check out the Midiplus X3 mini.
