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!

Vetro is a visual metronome that can synchronize automatically to a shared tempo on the network using Ableton Link protocol. Different visualization modes are included. Customize it by importing any animated GIF or Lottie animation (just drag and drop) and it will play in sync to your music. Use it in any of your devices (iPhone, iPad and macOS supported). On macOS, it can be freely resized to any window size and kept visible at all times so you are always aware of the current tempo. Blend it with your favorite apps by adjusting window opacity, and even allow mouse events to pass through so you can keep it visible while controlling the apps underneath. Use it as a visual enhancement for your recording sessions or as a new kind of metronome when practicing. Many devices can be used at the same time and they will all sync together. This may be cool when jamming! ## Features * 11 visual modes included. * 7 metronome sounds included. * Accurate timing. * Ableton Link synchronization. * Set any time signature. * Play animated GIF and Lottie animations in sync. * iPhone, iPad and macOS support. ## macOS-only features * Always visible option. * Translucent window: Adjust background and content opacity independently. * Pass-through mouse events.
