I have Kontakt 5, but I guess it’s kind of similar in Kontact 6.
For a start, I read this guide:
Then, a few hints. When you add a sample the first time it’s assigned to all keys in the keyboard, Kontact automatically shifts the pitch of that single sample, i.e. if you add a single E1 bass sample, all the notes in the instrument will be automatically filled (and pitch shifted by the Kontakt software, which is not ideal quality wise).
So what you need to do is to have a single sample for each note, see this picture, I tried to mark all the relevant parts:
Where the E1 sample is mapped on the MIDI E3 key.
In my “test” instrument I didn’t mapped different samples for different velocity (after all the purpose is not to have top quality in the DAW but to edit songs easily, after all the midi/loops will be played by beatbuddy in the end), but you can do that as well. Kontakt anyway deals pretty well with velocity.
Final hint, for saving, I think best option is save as “monolith”:
In this way you have a single nki instrument file including the samples, that should play also in the free Kontakt player (I guess I have a full version of Kontakt 5 too).
Not sure if I explained well, english obviously not my primary language, but in case write here or PM. Not a Kontakt expert, but if I can I’ll try to see if we can make it work.
I’m planning to do some more nki, so we can share the work, in case (not so much time really but over the week end or overnight).
And finally, thanks for all your kits/songs! I’m very new here, but I’m sure I’m already enjoining some of them!!!
