Hello TractorGirl,
Of the pedals used on Tyros only the pedal Yamaha FC7 (which is a pedal expression) can be considered analog because it has a specific potentiometer that manages the output audio level.
The other FC5 and FC4A Yamaha pedals only have one touch and could be replaced by a simple electric bell button.
The FC4A just has a more powerful return spring and a massive push button like on the pianos but still a simple touch on the inside.
All this to tell you that all pedals with a single touch can be used on a Tyros or Genos except the specific expression pedal FC7 to be purchased from Yamaha.
Now Yamaha also offers the MFC10 pedal that can handle a lot of parameters. It is not analog because it works in Midi mode and connects to a Midi port of Tyros or Genos.
Best regards
