Dear Fellow Reaperites! I wondered if any body can clue me up please? I sent some stems away in ver 3. I then updated to ver 4, I am pretty sure I set the stems to stem from position 0.00.000 After updating I got different measures like 0.00.467 as start postion in the Render box. Looking up the "Original" files I sent away under "properties", I see the "Start in Source" box has 0.00.000 My question in a nutshell is... "Does this position under "Start in Source" indicate the position the file was rendered from or originated from? Many thanks Grinder
