I believe it was @ComposerEverett here in the forum that liked working with Kontakt multis. I never did, but I have started to experiment with creating layered instruments. Meaning playing them in unison by mapping the same MIDI to each one, and thus be able to “sculpt” my own unique hybrid mix.
I am not sure if I like this over simply using the track stacks in Logic (you can record and play layered instruments in stacks in Logic Pro). But it does seem to be an interesting alternative.
Have you tried creating layered instruments in Kontakt for playing as “one complete instrument” in this way?
