Using OpenDeck building of MIDI controllers is simpler than ever.

Instead of spending time on choosing the right electronics, writing code, and solving lots of unnecessary problems, simply connect components of your MIDI controller into OpenDeck board and you’re done.

Additional board configuration can be done online  – no installation of extra software is necessary!
