This means that standard performance controllers (Pitch Bend, Mod Wheel etc.) are preserved properly and will be included in the note clip, just as when recording in Reason. If there are separate MIDI Controllers in the imported MIDI file, these will be imported to separate Automation Lanes on the Instrument Tracks. There is a chance that some controller data may be imported to alien clips, due to different interpretations of a controller by a device in the rack and the MIDI instrument used to create the MIDI file (see “About alien clips”).
