Bo Din, good information about the Kontakt Player.
As for the differences with Decent Sampler, these samples sound the same, with Kontakt using a different reverb (high quality free reverb plugins are a dime a dozen) and a saturation knob (free saturation plugins are also a dime a dozen). So the reverb and saturation could be swapped out with either version.
I found the DecentSampler version’s attack and release knobs to be really useful for getting just the right note decay length.
I don’t have Kontakt, so if I don’t have to play around with the Kontakt player limitation, I prefer not to. With this library, I don’t think it’s worth it.
