I just bought Lemur today and was setting it up and ran into this issue.
I have a retina MBP and they do not have an ethernet connection, so whenever I want to connect to my ipad for lemur use I have to disconnect from the internet. This is very annoying and I really hope there is a way around this. I run tutoring lessons via skype and really wanted to integrate my ipad into use for ableton while I did things that required an internet connection. Both of my thunderbolt ports are taken up with an extended display and external hard drive.
So bassically, I need to figure out a way to connect to my wifi network and also connect to my iPad device simultaneously or I need a refund.
Please help! I really want to integrate my Lemur into ableton without any issues!!
