Make the perfect MIDI controller for your music-making gear with MIDI Designer Pro X. Or, customize a community-shared MIDI remote MIDI controller for your needs.

MIDI Designer Pro X (MDPx) is the culmination of over a decade of continuous improvements. In 2012, we launched MIDI Designer Pro, which we relaunched in 2016 as MIDI Designer Pro 2. MDP2 was the first and only professional-grade MIDI controller built natively for iOS, earning widespread critical acclaim. Since launch, we have released over 80 updates, greatly expanding features and functionality. Our library of user-created content now covers over 300 MIDI targets covering a vast array of music-making gear and software. In 2024, we take a significant leap forward with MDPx. This release elevates the user experience to new heights on iPad and Mac -- including a new, expressive theme called "Spaceship" -- while advancing usability massively for iPhone users. 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.

What’s New

Version 10.5.0

Welcome MIDI Designer users to our 94th update to the App Store's best MIDI controller: MIDI Designer Pro X (10.5.0).

Introducing Sysex Strings! This is a huge for managing patch, kit and sample names on devices from Roland, Yamaha and others that speak Sysex.

Check out the fabulous docs and example from Kenyon at mididesigner.com/qa/10103. Big ups and gratitude to him for designing this feature from the ground up and advocating for it, gently, for over a year.

We've also revamped and future-proofed all sysex storage, sending and receiving. This release also provides a new option for play-mode: a button to toggle MIDI receive (to protect existing sysex strings in play mode). Also, coming soon: 14-bit "L" channel in sysex.

In addition, the Browse page inside the App should be 10x faster (and up to 300x faster in certain cases).

Having MIDI Designer Pro 2 available for Macs is a great enhancement of its capabilities.

For me, MIDI Designer Pro is a great app for both iPad and Apple Silicon Macs. I have been using it on my M1 Mac Mini for about a year. I find the larger size (I have a 27” monitor) extremely useful for designing layouts using a mouse rather than an Apple Pencil or my fingers on an iPad.

My retirement hobby is designing midi controllers for organists using Virtual Pipe Organ Apps such as Hauptwerk. Having both apps simultaneously active and displayed on one monitor simplifies the midi interface. While a touchscreen may be necessary for many MDP/Mac applications, using external pistons and/or switches from an organ console or keyboard to control MPD2 can provide unlimited possibilities for custom control and eliminates the need for an iPad.

Those familiar with the iPad and iPhone apps will find the behavior of the Mac Version is essentially identical. I found a few minor issues with using a mouse, but they are easily overcome.

Steep learning curve, but extremely versatile.

It really isn’t difficult once you understand it, but the interface definitely takes some getting used to. Once you do, you’ll be able to whip up a custom control set in no time.

I’ve barely scratched the surface so far. My semi modular synth only had a couple of assignable parameters, but there are over a dozen different options for one of the outputs on the patch bay that is buried deep in a menu (on a synth with no screen). I quickly figured out how to make a grid of buttons to send out the program change signal for each one. Now I can change the parameter instantly without having to even open the menu.

The app is definitely function over form, but gives you the tools to quickly design and program a MIDI control surface for your hardware and software synths, and any other conceivable use for it. Not to mention the integration with a MIDI-based scripting language. The possibilities really do seem endless.

I do hope the interface is easier to navigate in future updates. It is very difficult to make things look nice, and feels like the interface works against you. However, the devs are still active and frequently updating. I can imagine they have plans to streamline everything once they have most of the functionality set and major bugs squashed.

Developer Response ,

Thanks for this, we appreciate your feedback and will work to make navigation easier.

Best app for Virtual Organs

MidiDesigner Pro is the best midi controller app for Virtual Organs such as Hauptwerk (HW) and GrandOrgue (GO). Its capabilities are far better than traditional organ controller interfaces such as Touchscreen Monitors, Launchpad, Touch OSC, Luna Display, etc. Coupled with Stream Byter it allows many enhanced functions not possible with HW or GO by themselves. While there is a bit of learning curve, it is worth it.

I have developed such layouts as custom button placement, master generals and Combo steppers with PreSet starting steps to allow one touch selection and Up/Down sequencing of steps, Automatic registration setting, etc, None of this functionality would be possible without MidiDesigner Pro. I have worked with several organists to develop layouts for different organs who are extremely happy with using MDP. I have strong recommendations for organists to try it out.

Developer Response ,

Thanks so much for this positive and insightful review. We're so proud of users like you, Don, who are finding MDP2 to be an extremely useful tool in your quiver. We're also proud to be useful in completely novel spaces, like the virtual organs you control. Thanks again for all the work you do with MDP2 and for sharing. Big up!
