Reply to Banging drops

Hi,
I'm learning production, and as one of the first steps I'm trying to create the sound i have in mind with some VST.

But I was believeing about something :
For a drop, basically a single note that last 1 or 2 "beats" (1/4 or 1/2 of a bar), does everyone use a VST ? Is that acceptable to use samples packs and tweak them ?

I know samples packs shouldn't be use for leads and stuff, because if you want to have several note, the sound will be pitched up, and it won't sound as nice as a sound made with a VST. But what about single bass note for a drop ?

Thanks in advance.
