6.1 Merging function
Connecting two or more sources to the same destination, realizes a merging functions.
Beware that MIDI does not allow merging every type of message at any time. Merging two
sysex messages may lead to unpredictable results.

6.2 Establish connections
It is possible to connect any source to any destination, as a whole virtual cable or according
to message type.
Establishing connections is done from the connection tab of the CopperLan Manager
software application.
To connect a whole virtual cable, select the appropriate source device and click on the MIDI
connector icon. You complete the operation by selecting a destination. All messages
appearing at the source will be transferred to the destination without any filtering or
remapping.
Instead of connecting a whole cable content, it is allowed to connect individually one or more
message types according to the following split:
1. Note and Controller messages on a channel basis – these are channel messages
Any of the 16 MIDI channels content can be linked separately
2. Clock messages (incl. clock control and song position messages)
Any clock from any source can be connected to any destination. Note that MIDI
destinations can only accept a single clock whereas CopperLan destinations can
accept many.
3. Other messages (Sys)
This selection covers all messages to the exception of messages in categories 1 and 2
here above. This linking is essentially used for SYS EX and MTC messages.
It is meaningful to only connect sources and destinations of adequate messages type (e.g.
Sys to Sys).
However, it is allowed to connect any source channel to any destination channel, effectively
realizing a channel remapping.
