I believe so, yes....
Follow-up question: in general, and in particular with the Hub, if I ask a MIDI device to "receive" on a certain channel, it will pass through all channels if the output mode is "Thru," correct?
Same manual, pages 3 and 4:
MIDI Out Mode
Configures the function of the MIDI OUT hardware connector on the hub. In MIDI Thru mode, it sends out copies of whatever MIDI messages are received on its MIDI IN connector. In HH and Exp Out mode, it sends out continuous controller (CC) MIDI messages corresponding to a Hot Hand and expression pedal connected on its SENSOR IN and EXP IN ports, respectively.
