Add another 3 programmable switches to your Morningstar MC6 or MC8 MIDI controller. Or actually, you can buy two of theses and add 6 switches, because the MC6 allows for two of these if you'd like.

Talking about design, we made the center switch a bit higher to avoid hitting the two switches at a time (see pic). It also has the nice Click-Less switches to make it even nicer!

Dimensions:
4.39 x 2.34 x 1.06
