>> But..How do I get the song i enter on the iPhone/ipad rendered on my iMac? (I just get a "please enter server IP" when I hit the red play button)

You need to have a m4a copy of the song, so that you have My Song.mgu and My Song Render.m4a
The easiest way to do this is to load the song (eg. My Song.mgu) , and use the menu on the Combo radio button (top left of screen) and choose "Save song as m4a audio file". You will then have My Song Render.m4a
( repeat this process for any number of songs that you want to do)

Then run the iPhone version, choose File-Download and then you can use the Safari browser to select the songs. Note that you need to select both the m4a and the mgu in Safari. An alternative is just to make a single ZIP of all the files that you want to transfer (mgu's, m4a's , including subfolders), and they will download and preserve the subfolder names.

Note that you need to have Mac BIAB 2012, build 52 or higher for these functions.

Have Fun!
