I wonder principle mixer vst


#1

do you know send vst and mixer vst 

one day i watch this video

http://newaudiotechnology.com/en/products/spatial-audio-designer/

 

so they use vst plugin, but there are 3 types, one is send plugin, the other is mix plugin, last one is out plugin

 

so i try to make mixer track( empty track, like aux receive) and connect my test vst plugin. and i get only mixed sample data.(not seprate sample)

i can't get multiple sample.

so i think another point. is this use inter process communication, just send to sample data using vst plugin.  process in mix plugin, and send out plugin?
