The ID8 device is used by default when you're loading a Standard MIDI File into the Reason sequencer. For every MIDI track in the imported file, you will get an ID8 device loaded with a sound that resembles the original sound. This serves as a starting point to be able to play back the imported MIDI file. However, you could of course change sound, or replace the ID8 with another instrument device afterwards.
