Articulation lanes

I usually use noteperformer, but how do I switch the playing style of a sample sound source using articulation lanes? I’ve been working with DTM for a long time, but I’m not familiar with the concept of key switches, so I’d like to do it another way. Dorico has something called articulation lanes, so I’d like to be able to use that. For eighth notes, I’d like to use a waveform that’s appropriate for them, and for half notes, I’d like to use a waveform that’s appropriate for longer notes. Of course, it won’t be as automatic as noteperformer! I remember doing it with program changes back when I was playing Sibelius!
