All of these channels per project contain a Stereo-With Effect and a Studio-EQ with the (typical) adjustments for the corresponding instrument. The audio channels are routed to a sum channel (group). One for the Strings, one for the Woodwinds and one for the Brass instruments. Further, each of these sum channels is routed through its corresponding depth.

The depths are created with the Reverb plugin “REVerence”. The templates are optimized for different ensemble sizes.
Of course, you can also use each place in the concert room for any other instrument. But, you should probably change the EQ-settings in case of changing instruments.

Simply unzip the files and save the projects into a folder of your choice. If you open a project you are able to import corresponding audio files into the definite audio tracks...

or...
you are going to save parts of the mixer. Select for example all strings (audio-channels) and save the mixer part as “strings-Viol1-Viol2-Viola-Cello-Bass”
