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 at this point 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!

Great but missing 2 things

Great app, the panel menus are pretty clunky but eh whatever (It’d be nice to have notes instead of numbers for midi note-on values etc.), and being able to copy and paste messages instead of entire controls would be huuuge (copy/paste parameters from/to different controls) but there’s 2 things that keep it from being truly amazing...

1. Attack and release values for local-data and midi cc’s, as well as the ability to ADD TO and SUBTRACT FROM (not just SET) cc and other values (prefer hermmutt lobby’s beatsurfing app from 2013 for this reason). Ive spent a few hours with the Lua scripts and it’s not worth the effort for time based effects like this (may as well use max for live).

2. The ability for touch to pass through and hit multiple controls at once (not just the on that’s on top). No longer making "capture attention" required was a HUGE improvement (made it possible to make surfable/strummable instrument designs), but it’d be even better if you could hit both controls at once when they overlap.

Pretty fantastic app once you get it set up.
I just built a custom layout that is sent to my computer, and then back out via midi usb to my modular synthesizer. Super fun having four XY pads sent to filters and envelopes of my hardware synths. It was a bit confusing to get started however. And as far as syncing with logic pro, it seems like 50% of the time, it just won’t work. Could really use explaining the relationship between OSC and logic controller mappings. The manual is very matter of fact and could really benefit from small tutorials/step but step. OSC mappings really don’t make any sense to me, yet.

For my midi hardware setup, I just put the time in comparing the preset layout parameters to my custom layout. Soon enough it all started to make sense (midi). The editor is easier to use on the mac, but easy enough on mobile device. I recommend to anyone looking for a solid alternative/companion to your midi controllers. There’s definitely deep potential with this platform. Take it as far as you’re able/comfortable

Fully customizable control

This is an easy recommendation for anyone who performs in a MIDI environment.

I play keyboards for live theater, both scripted and improv. This app lets me move quickly during performances, due to the custom control layouts I'm able to create with it. It's an invaluably helpful tool that I'm very thankful to have.

And it's getting better all the time, both as I get better at making cool control layouts and as the decks continue to release updates. Their awesome support also extends to how dang good they are at giving thorough responses to support email queries. (Honestly maybe the best I've ever seen on that front.)
