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. CAPABILITIES • Control all MIDI-enabled hardware and software: keyboards, synths, effects, pedals, DAWs, plug-ins, DJ, VJ & lighting rigs, other iOS apps, robots, cruise ships, rail guns, particle accelerators • AUv3 MIDI Processor Extension: Host MDPx inside AUM, Cubasis, Logic, and other AUv3 hosts. • Solid MIDI Communications Infrastructure: Sets the industry standard for reliable and robust MIDI interactions over Network, Bluetooth and USB. • Active Community of Authors: A vibrant ecosystem supporting legacy and current music synthesizers, sound engines, DAWs, and all MIDI-controlled devices. • Extensive User Layout Library: More than 350 layouts for over 80 manufacturers, contributed by the Community. • Comprehensive Support: Whether you're just starting or tackling complex MIDI implementations, with the Community we are here to assist. • MIDI Designer's 'Superpowers': A suite of powerful features exclusive to MIDI Designer that we have developed over the last 10+ years, including: • Ableton Link and Link Control Loopers • Supercontrols and subcontrols as the basis for many features (with no scripting!): • Snap sub to value over time • Sequential subs • Subcontrol chaining • Button groups (radio buttons) with Bounceback™ • Steppers • Live Transpose • Group Presets • Named Ticks • Accelerometer • Simplified Sysex Messages with variables and bit changers • Snap to Value over Time • Global Presets • Pedalboards • Popup Panels (Show/Hide) • Two-up Page Layout for iPad/Mac • Streambyter Plugin by Audeonic for advanced MIDI transformation MDPx is easy to use, infinitely flexible and customizable, and battle-tested in performance.
