I forgot to mention that the time based effects CAN use MIDI Beat Clock.  You can sync your time-based effects to "MIDI" and a beat clock signal coming to the MIDI input behaves as expected.  This might be the config that you need to get working, assuming your HR16 outputs Beat Clock.

An expression pedal is just a variable resistance (potentiometer swept with a pedal), and not a voltage source, so the input circuit is designed around this resistance delta.  Clearly the output impedance swing of the signal you're feeding it isn't in the same ballpark that the circuit can use.  This is probably a big "DUH, of course not!", but I'm no EE and only going off of my basic newb instincts.
