EVS IPDirector Version 6.2 - June 2013 IPEDIT User Manual - Manual (Page 220)

Note
When you define a GPI for the mark IN and for the mark OUT points of the
Replace function, you need to define compatible GPI types, for example a level
high GPI for the mark IN GPI and a level low GPI for the mark OUT GPI. The
application will not prevent you from defining incompatible types.
Audio Swap Input Matrix
Introduction
When you use the Replace function, the current track selection in the timeline determines
which track will be replaced.
Note
Those settings will not be taken into account with the Live to Tape function.
If you want to route the result of the external mixing to a track other than the original one,
you can use the audio channel input matrix to configure how the audio channels should be
routed in the Replace process.
