Ableton has released the Max for Live Connection Kit, a free collection of 11 Max for Live devices.
If you’ve been looking to use Live with technologies like Arduino, LEGO® MINDSTORMS® EV3 and OSC, this free set of Max for Live devices provides exactly what you need. Now it’s simpler than ever to set up new and experimental ways to interact with and extend Live.
These devices allow you to connect, control and monitor Live with a range of innovative technologies and communication protocols. Use LEGO® MINDSTORMS® EV3, Arduino, or littleBits™ to connect up sensors, lights or motors, open your sound world up to the web through JSON-based APIs, or convert OSC data to MIDI data. The list of input and output possibilities for music & sound creation with Live is almost endless.
The pack is a free download for Live 9 Standard (version 9.5 or higher) and Max for Live.
