When I open up a project of mainly synthesized tracks with a lot of effects (I dabble in dubstep), the program stops playing and pops up a window that says "Nicht genugend Speicher", which, according to Google Translate, means "Not Enough Memory".  Why is this happening, and is there any way to get it to stop?

I am using MM16 Premium, and the synths I'm using are the VST synths that are basic with the program.
