Pling4 is a free plucked string model VST instrument with improved sustain and high frequency response thanks to hermite interpolation. The timbre is also significantly improved with a more complex pick impulse for brighter, crisper plucked string patches.
Pling4 features 8 voice polyhony. More accurate emulation can be achieved by using one legato instance for each string. Just add your favourite resonance modeler and amp sim effects.
