Hi Roy,

Thanks for the reply.

Indeed the discussion has become a bit diffused since to similar 
suggestions have been made, further confused by some cross-posting 
(shame on me again). I saw Jamie already replied from his part.

This is indeed what I was proposing. And came, of course without the 
deeper knowledge of QTR, to the same conclusion: conceptually, it 
could remain simple, but I see the UI might be a bit of a challenge.
I envision a slider per curve, like the channel mixer in Photoshop, 
but automatically balancing it to 100%. Not sure yet how to do that 
with a variable (>3) number of curves. Could you simply go for a 
list with a number (4? 6?) potential curves and a pull down menu per 
curve, where "none" is the default?  Or would that not be 
flexible/elegant enough or take too much space?

Aha, another naughty cross-poster ;-) ;-) !

I feel I'm just on the beginning of the split-tone journey. I still 
have to develop my own artistic judgement on what I want to achieve. 
So the curves do work for now, but I might very well need to refine 
them later.

As a matter of fact I build the Y-toner part in the K3T splittone 
from "scratch" (meaning starting from a normal K3 curve). First I 
made to cool2warm with LC as toner and then copied that approach to 
the cool2selenium with Y as toner. Perhaps I coincidentally came 
close to another similar curve. Out of curiosity: which curve are 
you refering to? 

Do have you suggestions for improvement?

One thing to add: I enjoyed this part of the journey and have 
started to appreciate QTR even more!

Joost
