Digital Nylon
Digital Nylon gives the impression of a nylon guitar sound.
An envelope delayed vibrato comes in if Aftertouch or ModWheel are used. You can change the Tone of the instrument.
It has an inbuilt delay. There is a Help button to label the controls. The sample rate you use affects the Tone of the instrument, I recommend 48000hz.
I also recommend playing with soft velocities in mind as a lot of the realism comes from the velocity dynamic, constantly playing velocities of 127 will cause the model to overload.
