i agree,those videos are awesome and it shows the type of flexability of session drummer and the things you can do with it.
for instance,i use seesion drummer as a triggering device at times.
sample a drummers live kick,snare,ride,hats,exc.
then i drop then in one by one into session drummers pieces.
the other thing i like is the ease of use.its really straight forward.
the drums are laid out and routed right to the console,like in real life.
more often than not im using a board to mike a real drum kit.
but there are those cases where drum replacment is needed or youve packed up the kit and at a later point in the project realize there is something you just dont like.
this is when sampling comes into play.
this is one of the reasons im not a person who has bought the expantion packs.
in my opinion,with one clean good sample with a good signal to noise ratio..you can make that kick sample sound like anything you want using effects.
nice posts man.
