Hi genemnc,
lol!
I believe you mean VDJ?! Right!
Tell us which version you use, then we can help.
To create effects and sampler, i'm not really the man.

But go to the main VDJ Site and have a look to the following link.
http://www.virtualdj.com/forums/14/Virtual_DJ_Plugins.htmlThis is the section where the real technical guys are.
There is a nice manual from DJ Cel(first TOPIC), read it

See you
LB
