Just got Kontakt 8.6 and wanted to explore the new midi tool. I'm at a loss as to what you can use it for. I can't figure it out and I couldn't find any doc or vids.
It's pretty simple really. You load it in conjunction with another tonal instrument like Claire Avant for example so that you see them both in the Instrument Navigator window. You make adjustments in Chord Builder for what type of chord you want to play like maj or min or maj7, etc. then by pressing the root key it will play that chord in your selected library. Hope that helps.
Probably not many vids if any because it's a very basic kind of tool.
There's this section in the Kontakt manual as well:
A video would be cool indeed. NI made one each for the Chords and Phrases tool.
