Hi,
I just tried to install the 3DTI VST for Windows and downloaded the reaper examples but each time I try to launch the .rpp file, Reaper crash.
I tried to open a new project and loaded the 3DTI Spatialisation VST which also lead to an instant crash.
I gave a look a the videos demos, it's very interesting and the binaural rendering is really convincing (Beyerdynamics DT990), bravo!
