Using Impulse Response Files to enhance Audio Modeling, SWAM Solo Strings Virtual Instruments.
In this video I'm using SWAM Violin V3, but you can use their SWAM Solo Strings V2 as well.
The IR files for the Solo Strings are from a company named : 3 Sigma Audio.

They also have a VST IR Player called Impulsive, which is pretty good. That's what I used for this test, and it allows you to load, and mix two IR files.
