Xmonsta has launched PULL, a touchscreen device editor for Ableton that uses the iPad.
It is an extremely fast and efficient workflow tool. Use it alongside other controllers, such as Ableton PUSH, or APC40, or any other controller, even a mouse.
In a nutshell, PULL allows you to edit fullscreen versions of every ableton device from your iPad . It follows any device that is currently selected and displays a very large, multi-touch template on the iPad for editing.
PULL is available for purchase for £25 GBP.
