Let me point you to the commandline version of the tool I have been using to do pretty much every monochrom edit in the past years:
I designed it (spoilerhead did the coding) many years ago, because all monochrome converters have at least on of a group of major design flaws in my opinion:
a) they try to bring film 1:1 to digital, which is a nuisance, because with digital workflow we are not limited to hardcoded films, filters or papers but can do anything parametric.
b) they work on a pure mathematical model without going for perception.
c) they ignore the fact that a good monochrome conversion has to build upon a perfect color edit. So a monochrome converter has to be the last step in the edit process, not somewhere inbetween.
If you want to try out a graphical implementation of Silicon Bonk, you would have to get a version of AfterShotPro (30 days tryout if i remember right) and install the plugin.
