Mastering with cubase

Hi Fellows!

i’m new to Cubase!
This is my situation:
i have this vst instruments:
1-drum synth (Kick Clap Hat Perc)
2- a piano chord
3- lead
4- bass
the problem is when i play the bass it just sounds noisy like harsh “phbbbt” but when i play the bass in solo it sounds good
on stereo out i limited and compressed the output under 0 db so whats the problem

Doesn’t sound very much like mastering to me.

Thanks for reply the key was Gain Staging!

That’s a new one :smiley:
