Thanks for the answer!

I reinstalled gimp to check it out but It seems like I only can assign one layer per channel, in krita you can have several layers creating each channel.

There's no way to asign wich channels do you want a specific layer to affect?

Three groups,  each group:

• The top layer filled with the channel color (Pure red, green or blue) set to Multiply mode
  
• The bottom layer is your channel image (grayscale or else, only the R,G, or B component will be taken in account
  
• Group set to Addition mode
  

Thanks!
but a ton of work for a simple thing!
In krita you click on the R, the G or the B....

OK, so I scripted it, see ofn-layer-decompose here.
