Ian, what inputs? I thought the FC7 went into the footswitch input.

That's what I meant, Beaky, the footswitch inputs. You might need to change the polarity as well.

It looks like the FC7 has a physical way to adjust the angle and the spring to affect the minimum volume. My Boss pedal has a knob to do this, but my PSR-S900 doesn't recognize it when I turn it. The slightest movement with the Boss has drastic effects on the volume.

I think I need to buy the FC7 for my purposes.

Roland and Yamaha have two completely different ways of reading expression from a continuous potentiometer (found in expression pedals). You cannot use a Yamaha with a Roland, and vice versa. It's not the polarity, but the taper (or slope) of the pot. Something about linear vs. log., or something like that.

Basically, if you want a pedal for Yamaha, use a Yamaha, or a Behringer (they are Yamaha compatible, and very good for the price). Roland... use a Roland (I don't know of a good inexpensive alternative to Roland)...

As you have noticed, although it SEEMS like they will work, you get ALL the action in a tiny fraction of the pedal's throw. Not really usable, IMO

Thanks Diki! I'll keep the Boss unit as a guitar volume pedal, but ditch it as a keyboard expression pedal.

But I don't think that the PSR-S900 will receive changes in the volume knob on the Behringer. The Yamaha FC7 has a way to physically adjust the minimum angle of the pedal. I just ordered the Yamaha. Thank you so much!!

How nice! An actual tutorial on SZ. What's next?

BTW, if you're playing live, either pedal will give you good volume control, just a different wiring path.
