Particles: Is it possible to control numerous starts and stops of one mesh emitter?

Is it possible to control numerous starts and stops of one mesh emitter?

For example:

I want generate particle for frames 30 to 80, then generate more particles from 150 to 260, and then 450 to 480. All from the same mesh.

I tired the IPO Time curve but that just controls the speed, even reverses it.

My current solution is to create multiple mesh generators with each one coordinated to start and stop for each specific frame period.

Currently, there is no way to do this with one particle emitter :frowning:

Aligorith

oh well. It was worht a try :frowning:

And thanks for the quick response.
