Kontakt Player in Logic Pro X and Existing MIDI Tracks

Hi all,

I am brand new to this so please be nice :)

I have a bunch of horn lines that I put in via MIDI into Logic Pro X. Now that I have added the Kontakt Player plugin, I'd like the horn section sounds I purchased to use the existing midi tracks with the purchased sounds. But I can't get it to work.

When I record, I get the sound, no problem, and it creates a midi track.

If possible, step by step, how can I take my existing MIDI tracks played by the Kontakt player horns I purchased?

TIA!

Jon
