Forte enables you to assign custom names to MIDI ports. If you use two different setups with different MIDI port hardware but use the same custom names, Forte will treat them as identical and avoid profile migration. For instance, you could assign "MIDI Port A" to be "My Big Keyboard" (naming it for how its connected). If two setups both have a "My Big Keyboard" port, they will be considered the same ports.
See Custom Names for details.
