MIDI Designer Pro X (MDPx) is the culmination of over a decade of improvement. We launched MIDI Designer Pro in 2012 and relaunched it in 2016 as MIDI Designer Pro 2. MDP2 was the first and only professional-grade MIDI controller built natively for iOS, earning critical acclaim. Since launch, over 80 updates have greatly expanded its capabilities. Our user-created library now covers 375+ MIDI targets across music hardware and software. In 2024, MDPx took a significant leap forward with the expressive "Spaceship" theme on iPad and Mac and major iPhone usability advances. It now adds AUv3 support in hosts such as AUM, Cubasis, and Logic. A new subscription model — Premium — allows even more users to use the App in their music-making and discover the App Store's best MIDI controller for themselves.
