I understand that the QS8 OUT can be assigned to be a THRU. What purpose does this have? Does this mean that the MIDI messages sent from the QS are mixed with incoming messages and sent out the OUT when the OUT mode is set to THRU? i.e.

1) QS8 Mode set to THRU
- THRU port sends only what is received at the IN port
- OUT port sends *BOTH* what comes in the IN port *AND* what is
generated by the QS8 itself
2) QS8 Mode set to OUT
- THRU port sends only what is received at the IN port
- OUT port sends *ONLY* what is generated by the QS8

Is this the case? Thanks all.
