Select using velocity notes

Hi,

is there any option to select just certain notes filtering by their velocity? Just suppose I have a layer of guitar and some keyboard sounds has filtered. If the guitar is really present (and shown with a stronger color) can I select all those sounds automatically with a filter and bleed them into another layer so I can leave the sounds of the keyboard and work with both layers separately, instead of having to choose one by one all the notes of the guitar?

Thanks.
