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.

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!

Long time user

I discovered TouchOSC a few years ago and it was a great idea with all kind of smart tablets and phones out there. I am mainly a Cubase user and tried to program this for a long time until I finally understood how it works (well, maybe 90%). I was able to make a Cubase template that is close to a hardware based surface control costing $600 and above. My template is on Steinberg’s forum site for you to check it out.

Some very high end sample library companies even provide templates to be used with their software in Kontakt like Chris Heins Violins. That shows you the capabilities.

Like other users here, I would like to see some visual improvements and expanded manual and some good examples. You really need to have a great imagination of what you want to achieve and the possibilities with TouchOSC but for someone who lacks the imagination they will probably pass this on.

It is an essential part of my setup and highly recommend this.
