To save ram and after loading various instruments into either the
kontakt or kontakt player2 racks how does one make each instrument
loaded coincide with the different midi tracks in the logic project ?

example

flute II
oboe I
oboe II
clarinet I
clarinet II

logic tracks
1 piccolo
2 flute I
3 flute II
4 oboe I
5 oboe II
6 clarinet I
