Marker Track
I created a new project in Cubase and added a marker track using the Project>Add Track>Marker menu option. A marker track will allow me to annotate the major sections of your song. Although the final structure of the song is not yet known I add a few basic markers such as "Intro", "Verse 1", "Chorus", "Verse 2" and "Outro". I will position these and add more markers later as the song develops. The markers will allow me to plan and navigate easily around my song's arrangement.Reason ReWire
Reason ReWire allows you to slave the Reason software to Cubase. This would allow me to use the MIDI facilities and virtual instruments in Reason and ensure that they are completely synchronised to the Cubase tempo track. To use Reason ReWire you simply start both Cubase and Reason, select the Devices>Reason ReWire menu option and switch on the Mix L and Mix R reason channels.
Tempo Track (i.e. Click Track)
If I need to vary the tempo and / or time signature within different sections of my song then I will need to use the Cubase tempo track editor. The tempo track editor is accessed via the Project>Tempo Track menu option. The pencil tool can then be used to change the tempo at a specific point and / or the time signature (e.g. from 4/4 to 5/4).
When the click sound is enabled the tempo track becomes the click track, The click track is essentially a metronome, which allows the performer to keep strictly in time with the songs tempo. Playing accurately to a click track allows much easier editing of audio and MIDI data after it has been recorded. Audio and MIDI data can be copied in bar units when it is synchronised with a click track. Delay effects can also be synchronised with the tempo track.
