Yes, currently when combining mask mode with external, external is the 
generator and mask mode is an amplifier (eg. word -> word1, word2, word3).

We should probably support the other way round too, eg. mask generator 
and external filter. But what would the option syntax be for selecting 
behavior? If nothing else, an external mode that lacks generate(), like 
in your case, should automagically select mask mode as the generator.
