More thoughts on MIDI merge and the PSR9k.

From the PSR9k manual on page 149, it sounds like there is may be a MIDI-merge function at least in some cases. With a computer coupled to the TO HOST port and the appropriate selection made for the TO HOST selector, and with "THRU" set as the MIDI mode, it sounds like there MAY be MIDI merge.

The next question would be whether connecting an external controller to MIDI A IN with the TO HOST selector on MID and the MIDI mode set to "THRU" would result in MIDI merging. This is the same as the test I described in my previous post except the external connection to to MIDI IN A instead of MIDI IN B.
