Sometimes when I make a synth in massive and put it into a piano roll and the synth repeats through the piano roll and it will sound different every time... anyone know what i'm talking about or experienced this before?
For example (please excuse my idiotic description i know how dumb i sound... bare with me

) it would sound like this after the piano roll repeats: wub, wab, web, woob, wub, wab, web, woob. (although the synth i'm having trouble with is a Yo sound but i think it's better described with a wub lol..)
It is still the same sounding essentially but something keeps changing and i'm not sure what it is and haven't figured it out. Any help? If i need I can upload a repeating piano roll up on soundcloud if nobody knows what the hell i'm talking about haha
