Question

if someone recorded a session on an apple using logic x is there a way I can open that session in studio one 4 on a pc with out messing up the timing or arrangement

Answer 1

Both Logic and Studio One support OpenTL, so you should be able to save your session in Logic as an OpenTL file, then you should be able to open that OpenTL file in Studio One.  I've never tried it, so I don't know how well it works.

Another method, and perhaps the most common method, is simply exporting all of the tracks in your Logic session as audio stems and then importing those stems in Studio One.
