It's called "active sense" or "running status." Whenever the synth is not
actively used, it sends out an "I'm still here" message every
~300mSec. It's supposed to prevent stuck notes by detecting when devices
drop off the line, but various manufacturers seem to respond differently to
it, and it actually seems to CAUSE stuck notes in some combinations,
because the receiving device has to filter it out of the
stream. Personally, I wish it could be turned off. I notice that my
MIDIMan 8x8 patchbay accepts the command (input flashes) but doesn't pass
it along (output light stays off), even when in Patchbay and Thru modes.
