I’m having problem with properly using my FC3 sustain pedal because my voices sustain for a long period if I keep my food down on the pedal, and as I try to gauge the portion, it takes away my concentration from playing. How can I sustain with the pedal like I do with the PSR-295 which has a sustain toggle switch on/off?

>>> if I keep my food down on the pedal ....

... depends on what you eat.

;JOOP!

Forgive a brotha, I meant foot… lol

Sorry, only kidding.
Although ..... weird people here, you’ll never know.

About sustain: I play real grand at my teachers’ and I got used
to keeping the pedal down for long times.

Have you ever thought of prolonging the notes (=voices) themselves?
I mean, there’s lots of voices that go on for many seconds
after key release.
Just a little editing in the afternoon ............

;JOOP!

It’s a shame that Yamaha didn’t add a polarity switch within the OS. Even my Yamaha and Casio Home keyboards let alone my Korg and Kurzweil keyboards have included such a feature. wondering if polarity is Hardware or Voltage specific?

The word ‘shame’ appears too often in this forum, without any knowledge of possible Yamaha’s intentions.

;JOOP!

Assuming everyone has the correct pedal (i.e. Motif 8 needs an FC4 pedal) and it worked before with no issues; try doing a factory reset. My pedal worked for years, then one day not. Did a factory reset and voila!
Google “How to do a Motif 8 factory reset” for the few simple steps.
Only thing is you might lose any permanent settings you made or songs saved. You might have to back up first?
