The white elephant of the keyboard controllers, 32 and 37 key MIDI controllers are the rarest key configuration. Leading the way in 2023 is the IK Multimedia – iRig Keys Pro as well as a keyboard from one of our favorite brands, the Arturia KeyStep.

For this list, we will move through the best 30-something keyboard controllers that are still available to the public, even if it’s bought through a private sale. Here are the best 32 and 37 key MIDI controllers:

What sets the Grand apart from the Rise are a few specific choices that you have to make when choosing to buy one or the other.
