The pedal has smooth output throughout the pedal's travel. I tried an FC-7 (Yamaha) before this pedal and it didn't have linear output throughout the pedal's travel. It was difficult to make smooth volume/expression changes.
The EP-3 has a "scalable output knob." I thought that would be a way to require less pedal travel to go from 0-127. Not so. I'm not sure what good this knob will do.
I ran some tests. FWIW.
Setting the knob all the way counterclockwise, my keyboard reflects that setting is data equal to zero. Moving the pedal results in no data. It's zero no matter where the pedal is set.
The position of the pedal is somewhat important to the results you'll see below. I set the knob with the pedal all the way up (heel all the way down). This is the low value position.
Most of the time, the knob changed the setting by two's, but it would also sometimes jump by one -- sometimes even numbered, sometimes odd. I moved the knob clockwise until there was a change in data.

Here's where things get strange. The low number starts decreasing while the high number increases. And I'm still turning the knob clockwise.

Does anyone know the logic behind this?
As for the pedal, it feels expensive. There is a pneumatic kind of feel to pedal movement. That will probably change over time, but it's nice now. The base is metal. The working parts look like they're metal. The upper case/pedal is plastic, but it seems to be tough. It's heavy enough not to slide when you're trying to use it. It's comfortable when used seated or standing up. The pedal travel is sufficient to enable accuracy in volume/expression changes.
I hope this helps someone out there.
