The ID8 Instrument device is a synth module packed with great sounds - ideal for quickly creating nice complete arrangements. The sounds have been extracted from various Reason devices and ReFills to guarantee supreme audio quality.
See “Velocity mapping” for information about the velocity mapping of some of the sounds.
The ID8 device is used by default when you’re loading a Standard MIDI File into the Reason Essentials 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.
