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!
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
Recalling the glory days of the universal patch editor/librarian, Patch Base is a free iOS app offering in-app purchase of individual instrument editors. 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.
Crudebyte MIDI Wrench
The purely utilitarian MIDI Wrench is a visualisation tool for MIDI data. Plug any MIDI device into your iPhone or iPad and you can see - at a glance - exactly what MIDI data is online, and view messages as they’re sent.
Freely assignable virtual MIDI controllers and a keyboard are also in play. An essential tool for MIDI users.
