Basically I've got a picture of all 6 strings on a guitar, and each string is assigned to a separate layer.

I want to split these 6 layers into 120 layers by splitting along the 20 fret lines. I started by making a selection of each fret, and then 'layer by cut', but this will take too long. Can anyone give me a quicker way?

The reason I'm doing this is to apply a separate blending options set to each fret on each string, so if there's an easier way to do this, I'm happy with that.

grouping the layers? then cutting, then trying to ungroup them? or Hiding/disabling the background, so it is uneffected, and work with the top layers only. – Psycogeek Oct 6 '11 at 10:53
You can't cut with multiple layers selected, even if they're part of a group. – Miguel Oct 7 '11 at 1:54

The easiest way I found to do this was select the first string, select each fret, and then do 'layer by cut', and go to next layer with 'ctrl + {'. all the while recording the process as a photoshop 'action'. You then then play back this action on each string separately, so you only have to do the cutting process once.

I'd still like to see a solution for simply cutting multiple layers though.
