Hey thanks for the replies.
Yes I have latest Rapture Pro and Reaper - both 64bit and have reinstalled both several times.
I downloaded Sonar demo to test and the patches play fine.
It only occurs in Reaper using the 64bit version of Rapture Pro. Very Odd.
So far one person has replied on the Reaper boards to say everything is fine so it appears it's just me. Obviously that doesn't help my situation though.
I'll try "enable logging" as suggested above.
Does anyone know if Reaper has any support or do paid up users just use the forum?
If the reaper forum is the only help then I might be out of luck to find an answer. Surely there's a solution though??
Any other ideas?
Thank you.
