XMonsta has released PULL, a touchscreen device editor for Ableton Live 9 that uses the iPad Lemur App. It is a fast and efficient workflow tool. Use it alongside other controllers, such as Ableton Push, or APC40, or any other controller, even a mouse.
PULL allows you to edit full-screen versions of every Ableton Live device from your iPad. It follows any device that is currently selected and displays a large, multi-touch template on the iPad for editing.
The software uses a combination of Ableton Live, Max for live and the Lemur iPad app to achieve this.
Here's what they say: "We noticed that while there are some great controllers for Ableton, most of these lack intuitiveness when editing devices (only allowing you to edit the 8 banks of parameters at a time, using generic knobs). PULL is set to change this, providing much larger, full screen, multi-touch versions that are designed to look just like Ableton devices."
There are templates for every Ableton device included.
