It seems 64bit builds for some reason have problems with VST Sync feature on, workaround seems to be converting VST sync patch from double to floats, which does work both with 32 and 64bit builds. Double precision seems to produce odd numbers with 64bit build. (tested on VirtualBox Linux Mint 14.1 64 bit OS) (cherry picked from commit 011f87e6e60cccd16f3783e9c4885e03d95c1e56) Signed-off-by: Tobias Doerffel <tobias.doerffel@gmail.com>
