Ableton's Push controller for Live has been an awfully tempting new piece of gear. At around $600 it is very pricey for what is essentially just some buttons and a Python script. This script is how Ableton interacts with controllers, sending meta-data in addition to MIDI commands.
It was only a matter of time before someone figured out a way to use that same script on a Lemur template, and Lemur user WUL has done just that! Registered Liine Lemur owners can download Shove for free.
Create Digital Music tested it out and was very pleased with it. One caption at the bottom of the article is particularly quotable:
"Remarkably, once installed, using the iPad app in emulation means Ableton Live can’t tell your tablet from an actual Push."
