Hello

I am having a mess around with Native Instruments Strummed Acoustic and there are some key switches in red and also some other switches in yellow when you bring up the keyboard in Kontakt.

These are for end notes of a song and when people show you how to use them on youtube it works, but when I go and try it they don't work and the current pattern keeps on playing.

What am I doing wrong, could anyone help me please

Thanks
