Liine continues to release little introductory videos for the new layouts they have for Lemur. These are all totally free and available on their website. This one is much more informative than the last. Even if you don't have a Maschine, the video offers a good look at the advanced scripting available in Lemur.
SL-M1 is designed to allow Maschine to be controlled using Lemur on your iPad. By placing controls for up to 64 parameters within reach, SL-M1 allows performers to have a level of control that would otherwise require many sets of hands and some very quick button pressing. All of this allows for much more complex and interesting sets.
