Interesting that you chose the “Bamboo” instrument, since it specifically says:
“Multiple reverbs and delays were stacked together to create a mass of sound, and then captured as an impulse response. The IR was then used in Kontakt along with some more reverb and delay. (emphasis mine)
It seems you went to a horse auction, somehow bought the only camel on offer, were surprised that it was not a horse, and then proclaimed that all they sell are camels. (just pulling your chain haha).
So, out of curiosity, I downloaded the Bamboo instrument and listened to the raw sample. It is super dry. If you are handy with Kontakt, you could create your own instrument with that sample mapped (I believe it is an A, there is only one.) Alternatively, you could click the wrench to open the instrument, scroll down to where it says Instrument Send FX, and delete them all (convolution reverb, reverb, and delay are there), scroll down to Modulation, and you can play with the Release length. Should make it as dry as the original sample.
1. This is pretty simple to do. It is really a basic concept within Kontakt. If you have a look at this video: How to Creat a Kontakt instrument
the link should skip ahead to 6:46 where he shows how samples and velocities are mapped. The samples for your instrument are already mapped, so you just need to drag a few velocity cutoffs up.
2. As far as sharing… well, it is so easy, it may not be worth putting the pianobook team through the hassle of creating a new instrument page just for that.
One thing not mentioned. While Spitfire does make a sample player that could be seen as a competing product to Kontakt, most of what they make is sound libraries that are used within Kontakt (that is what you saw as the colourful Spitfire strips on the Kontakt screen).
Also, buying Kontakt and Spitfire to do a little light background music for an audiobook, would be wildly overkill. Unless you have $1000 burning a hole in your pocket, you might want to look at the Spitfire LABS free set of virtual instruments, the Spitfire BBC Symphony Orchestra Discover (also free, requires filling out a survey if I recall), and any library on this site for the DecentSampler sample player (also free).
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.
