About third party content
On the DVD, you will also find the “HALion 3rd party Demo Content”
folder. This contains demo content from different providers (ELab,
Gary Garritan, Scarbee and Vienna Symphonic Library).
Also included in this folder is a demo version (PC only, limited trial period
of 15 days after installation) of Zero X Beat Quantizer 1.0. This
application for slicing and quantizing audio samples uses the .zgr file
format which can be imported into HALion.
