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.

Brand-new app. Brand-new powerful editor. We've listened for the past 10 years and we've re-written the application from the ground up - with speed, features and usability in mind. A GPU-powered, fast and advanced integrated editor is part of TouchOSC on all platforms - create the most complex of control layouts with ease and precision. MIDI, OSC and more... TouchOSC supports sending and receiving any number of MIDI and OSC messages on many connections simultaneously. On top of OSC over UDP & TCP, we support every type of wired & wireless MIDI connection your device can offer, including MIDI over USB. Cross-Network. Synchronized editing. Multiple instances of TouchOSC can be connected on the network for synchronized editing. Use the precision of your desktop's mouse and keyboard for fine-grained, detailed editing - test-drive and preview in real-time on all connected touch-screen devices at the same time. Scripting and local messages. A lightweight and fast scripting engine allows deep access to all aspects of your controller and enables limitless customization and interactivity. For less complex tasks we've added local messages - simply wire up controls to transmit or display values; no need to break out the big (code) guns. Easy. This is only the beginning... We've supported and updated TouchOSC Mk1 for more than 10 years and we're planning to do the same for this new version. We've already got a whole bunch of features cooking that were just not quite ready yet. There is so much more to come... Welcome to the next generation!
