I was reading through a book when I came across this lick. I tried to represent it in guitar pro but am finding difficulty. Can you please help me with this lick? I understand that these are grace notes but I am not able to add effects to the grace notes like prebend and release. Is there something that I am missing?
You need to use the bend tool (p95) for this kind of things. It will allow you to add prebends and release part on a bend.
There is also a "prebend-release" which should match pretty well what you want to do.
Hope it helps,
