6 of the best iOS MIDI controller apps

By Computer Music
published 3 July 2017

Turn your iPhone or iPad into a multitouch control surface with these amazing apps

Hexler TouchOSC
£4.99/$4.99

Hexler TouchOSC

There are loads of great MIDI controllers on the App Store, from simple fixed-CC generators to elaborate construction systems for designing your own perfect touchscreen control surfaces.

Here are six of - in our opinion - the best, kicking off with Hexler’s touchOSC.

Using an application on a desktop computer, touchOSC lets you create your own Open Sound Control-based control surfaces, sequencers, DAW controllers and more, before loading them into your iOS device. It’s surprisingly easy!

Buy Hexler touchOSC on the Apple App Store

One More Muse Control

One More Muse Control

Similar to TouchOSC, Control is a free app that gives you the power to create custom control surfaces that can be linked to target hardware and software through OSC or Wireless MIDI.

This one is open-source and available for both iOS and Android devices.

Justus Kandzi Trigger Box
Free

Justus Kandzi Trigger Box

This is a neat idea. Trigger Box generates semi-random gate and trigger signals through the audio output of your iPhone or iPad, which can be used to trigger analogue synthesisers and modules – though you might need to amplify the signal on the way to its target.

A step sequencer can be added for a buck.

Coffeeshopped Patch Base

At this time there are 30 profiles of popular synthesizers from Korg, Roland, Yamaha, Oberheim, Clavia, DSI, Casio, and Ensoniq, with more being added all the time.
