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, 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.

Please see for more information, video demonstrations and download the free layout editor application for macOS, Windows and Linux and the free TouchOSC Bridge utility to easily control any MIDI-capable application on your computer.

Cockhat ,

Bravo! This is the missing link

At least it was for me. Somewhat obsessed with midi controllers and had been tweaking a live loops set up and for some time just always had that 1 button or command that I didn’t want to have to press. I have had like 5-6 of the more well known midi to daw controllers (notation, Akai) and still use those plenty.

But this app magnificently does things that none of those controllers can do. This helped me creatively, technically and now I have a lot more flexibility to do more interesting thing in my sets and continue the exploration.

I have never written a review before - this app is a must have if you do anything with MIDI

Not giving up yet 😂

I’ve been at this TouchOSC for a few days now, created custom layouts with Toggles, Rotaries, Push Buttons , Faders, XY Pads and Multis to use for virtual instrument libraries within Logic Pro X, Kontakt and other plugins. I am getting the hang of it.
Though, it seems that, using TouchOSC over a network connection at times chokes up notes on MacBook Pro 2015 with 16 gigs of ram and SSD Drives. Need to do more trouble shooting with TouchOSC & Osculator. I am thinking maybe Osculator is the culprit here.
It would be nice if Hexler would make TOSC USB capable as well.
Other than that I like the TOSC. As mentioned in other previous reviews, it would be nice to also have more choice for colors and graphics.

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!
