Reply to Mapping Suggestion to Control Effects

I have a Kontrol S4 which I use as my main controller. However, I also have a Maschine Mk1 and a Kontrol F1.

I'm feeling that the only limitation of the S4 really it the lack of simple to access and use effects. Therefore, hoping to be able to use the F1 (ideally due to smaller size) or the Maschine as my effects controller.

Anyone got any suggestions on best mappings and ways to use the F1 (or Maschine) as a kind of MidiFighter replacement?
