Can anybody demonstrate how to do a vocal riser in Halion just like the link below
Create Vocal risers using Kontakt in Cubase 8
you just modulate the pitch of a sample with a slow LFO. Make sure the LFO is not trigger based. Are you asking how to modulate in Halion in general? You could also automate/modulate(same function really) the pitch parameter on your DAW timeline. You get more control that way.
