Hey ho. That's true !

I looked at the picture, MusE is detecting midi sync on the 
 one green 'C' light - the Lexicon. 
But MusE definitely should not attempt to sync to it if 
 "Slave to external sync" checkbox is off, even when the 
 'RC' (Accept midi clock input) column is checked.
Lemme know if that ever happens.

However if I recall, the 'TC' (Send midi clock output) column operates
 /regardless/ of the "Slave to external sync" setting.
So in that picture MusE would be transmitting clock to ALL your devices.

Also, midi sync may not be the problem here:

Virtually all of your Transport Receive and Transmit column options 
 are checked green.

As you know these other columns enable other types of messages, 
 such as midi positional commands, start, stop etc.
Note: They operate /regardless/ of the "Slave to external sync" setting,
 if I recall correctly.

So MusE in this case will transmit and respond to such commands which 
 may or may not have messed up the recording.
Especially if there's a midi send /and/ return to the Lexicon -
 you might be getting 'echos' from/to MusE, to/from the Lexicon.

Also, in general you only want one of each of the 'RR' 'RM' 'RT'
 columns and especially the corresponding 'TR' 'TM' 'RT' columns -
 in your picture MusE would transmit three /different/ types of identical 
 midi transport commands position, stop, play etc !
Usually you want either the Realtime commands, or the MMC commands,
 or the MTC commands.

Lemme know if there's any trouble with MusE sync, I can answer any questions.

Me too.
