MIDI Monitor Showing Duplicates

I’m seeing duplicate entries in the MIDI Monitor for both Msg1 and Msg2 on this preset. I was intending to set up an “infinite repeats” type of button for a Boss DM-101. It works great, I’m just curious about the duplicate messages.

A quick 2nd test and I’m seeing duplicate messages on a single message preset, Msg1 has Press with Type = CC. This time the timestamps vary by 1 thousandth of a second.

Is this intentional to handle a MSB LSB situation?

It might be related to the USB Virtual MIDI port setting under Controller Settings >> General config.

MC has 4 virtual MIDI ports. That setting determines how many of the ports to send the message out to.
