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 application allows to remote control and receive feedback from software and hardware that implement the OSC or MIDI protocols such as Apple Logic Pro/Express, Ableton Live, Renoise, Pure Data, Max/MSP/Jitter, Max for Live, OSCulator, VDMX, Resolume Avenue/Arena, Modul8, Plogue Bidule, NI Traktor, NI Reaktor, Quartz Composer, Supercollider, vvvv, Derivative TouchDesigner, Isadora and many others.

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.

First day using the app and my life has already gotten better.

After downloading the editor and importing the layout for the hog 4 by high end systems. It was easy to set up and after playing with it for a couple hours I figure out how to designed my own layout that was a plot of one of the sets on the show I’m working on. I used buttons that when pushed would trigger a keystroke macro that would add the channel(s) into my command line. Having the control and efficiency that this app has enabled is amazing for how inexpensive it is. It was money well spent!

Works great, really ugly!

Let me say, this is a fantastic piece of software that works reliably and does everything I might ask for - my 5 star review reflects that. My only complaint (and its a pretty big one) is that it’s UGLY. Controls are limited to a single shape with 8(?) colors to choose from. Let us customize an RGB value for the color. More importantly, let us import our own graphical assets to use as buttons - it would take this app to an entirely new level.

Thank you for your work!

Super versatile, great app for experimenters as well as professionals.

I've been using this app since it came out. I use it to control many different hacker-y projects. If you make anything that has a network connection, you can probably use this to control it.

I use this mainly with plogue bidule, but it also works with pure data, max, and many other great tools.

Well done, and thanks for providing this!
