OSC and MIDI control surface

TouchOSC is a modular OSC and MIDI control surface for iPhone, iPod Touch and iPad by hexler.

It supports sending and receiving Open Sound Control and MIDI messages over Wi-Fi and CoreMIDI inter-app communication and compatible hardware.

The interface provides a number of customizable touch controls to send and receive messages:

Faders / Rotary controls / Encoder controls / Push buttons / Toggle buttons / XY pads / Multi-faders / Multi-push / Multi-toggles / Multi-xy pads / LEDs / Labels / Time & battery displays

Additionally the program can send Accelerometer data. The application comes with example layouts and completely custom layouts can be constructed using the free TouchOSC Editor application.

Still fantastic

I remember using this app nearly a decade ago. I downloaded it recently to use my iPhone to control buried parameters on my HX Stomp and Boss VE-500 vocal processor. I use it when setting up for a gig (to adapt to the venue). It works flawlessly with the Apple Camera Connector. The editor on Mac also works flawlessly, and transferring layouts from Mac to the iPad/iPhone takes 5 seconds over WiFi, no hassle at all, no cable needed, always works. Super customizable too. Thank you for this! Hopefully my review will help others like me who were unsure if this actually still works. If you need to control MIDI using your iPhone/iPad, it doesn’t get any simpler than this!

Difficulty connecting to Mac/Mainstage

I found the process getting Touch OSC to work with my Mac running Mainstage very challenging and took many steps including downloading 2 other apps on my Mac to make it work.

Even then it only worked 1/2 of the time and was always quite the process to get Touch OSC to connect with Mainstage on my Mac.

Useless with ableton

This is pretty useless with ableton, if you have the required technical knowledge you can get the scripts installed, but all the able support is very old and by directional views of things like clips playing aren’t really supported
