That really is simple to do in a little loop. People usually discard the
first n elements of a vector of size n+N, say n=100,N=1000.

As for the jump diffusion part, you are adding a second model on top, so why
not make an explicit mixture?  Draw a uniform, and if >\alpha, add jump
\epsilon, or an entire process, or ...
