Weird noise in vst drum tracks

[jdacapo]

I was working on a beat using piano-roll vst drum plugins, and I've noticed when I'd play three of those plugins together in the beat creator, they would make a sort of weird noise. It wasn't quite obvious when all tracks were playing, but when I would solo or mute one of them, it would play that noise until I muted all drum tracks. Is this a problem with the program itself or a vst plugin glitch?

what vst-plugin did you use?
Is it on the 'safe-vst-plugin-list'

One thing that is a known isue is that is the same percussion sound is played dually there is a distorsion, but that is simply because of clipping. 2 or more simultanious identical sounds 'doubles up' and couses clipping, whitch also is visually shown both in the mixer and the graphical visualisation display, but your isue may be different, since you use a vst-drumkit -But what is the name?

It's not on the list, and I do have hundreds of vst plugins. I'll have to check to see what the name of the plugin is.
