There is no such thing as a simple MIDI combiner. Due to running
status which was in the original MIDI spec, it's not a simple
task. A MIDI merge routine must examine the input, determine
the length of the message and then send it out before merging
data from the other input. And if one of the inputs has notes
with running status, the merger must be smart enough to output
the channel and message type before appending the note number.
While I'm sure there a some new PICs out there fast enough to
merge two MIDI streams I don't know of anyone who has made the
code publically available. If you like pain and misery you can
build your own 8031/51 based unit. Go here for more details:

$89. Or buy a used Digital Music MX-8 or JLCooper MSBrev2.
