## What is TouchOSC?

Brand-new app. Brand-new powerful editor.

We've listened for the past 10 years and we've re-written the application from the ground up - with speed, features and usability in mind. A GPU-powered, fast and advanced integrated editor is part of TouchOSC on all platforms - create the most complex of control layouts with ease and precision.

MIDI, OSC and more...

TouchOSC supports sending and receiving any number of MIDI and OSC messages on many connections simultaneously. On top of OSC over UDP & TCP, we support every type of wired & wireless MIDI connection your device can offer, including MIDI over USB.

Cross-Network. Synchronized editing.

Multiple instances of TouchOSC can be connected on the network for synchronized editing. Use the precision of your desktop's mouse and keyboard for fine-grained, detailed editing - test-drive and preview in real-time on all connected touch-screen devices at the same time.

Scripting and local messages.

A lightweight and fast scripting engine allows deep access to all aspects of your controller and enables limitless customization and interactivity. For less complex tasks we've added local messages - simply wire up controls to transmit or display values; no need to break out the big (code) guns. Easy.

This is only the beginning...

We've supported and updated TouchOSC Mk1 for more than 10 years and we're planning to do the same for this new version. We've already got a whole bunch of features cooking that were just not quite ready yet. There is so much more to come... 

Welcome to the next generation!

### 5/5 — Once you understand it!

*2026-06-24*

I purchased a few weeks ago, and there’s a learning curve, not terrible but you have to learn what you are controlling and how. Dramatically changed the way I compose.

### 3/5 — Issues at first then resolved

*2026-05-15*

After many hours of trying bridges for my iPad and on PC frustrated and giving up I put down my iPad and the screen rotated!!! Guess what!? Icons for connecting to my device appeared. Works as advertised at that point.  No where did I see that the iPad needs to be in landscape mode.  So many hours wasted. I did raise my original review from 1 star, but because of that 3 is the max I can do.  The instructions are not clear and just a ton to sift through saying need install bridge, click icons that are not there.  Step 1 in instructions and FAQ need to be turn your tablet to landscape mode.

I’ve been using this app for years now. It’s the perfect app for custom control surfaces. I use it for both studio production and live performances and it never fails on me. You can create whatever controls you need easily.

### 1/5 — A nightmare…
