Play the instrument with some of the variations allowed by the physical original.
You can use multi-track techniques to isolate expression control of more than one string, or enable MPE in Surge and your DAW.
|Lowers the high-frequency components of the guitar.
|Set low, this gives a hard pluck with sudden excitation of the string. Set high, this rubs the string with a finger pad as it is released, for a soft excitation.
