FWIW the VPC1 has pedal inputs and it comes with a three pedal unit with half damper function. It also has MIDI in/out connectors and USB. What it doesn't have is any knobs of faders.
Yes, it has the traditional three pedal piano setup (to be used with the triple pedal they designed). It doesn't have a pedal input for controlling expression/volume, or pitch bend/mod wheel, or as you said, any knobs or faders. It's really designed to be like an acoustic piano, and that's it. Really does that job well, though.
