INFIX is a utility module for inserting or replacing channels in a polyphonic cable. By default the module sends the POLY input without change to the POLY output. As soon as a cable is connected to one of the monophonic input ports 1-16 the channel on POLY output gets replaced (in case it is used by POLY input) or added (in case of an unused channel).
INFIX was added in v1.0.3 of PackOne. µINFIX was added in v1.3.0.
