Timebase - Applies to an entire Track. A Track’s Timebase determines if Events on the Track have their START Location measured in Bars & Beats or Minutes & Seconds
- Musical Timebase - Start is measured in Beats
- Linear Timebase - Start is measured in Seconds
Musical Mode - Applies to an entire Audio File and will impact all Events created from that file throughout the entire Project. A File’s Musical Mode determines if an Event’s LENGTH is measured in Bars & Beats or Minutes & Seconds
- Musical Mode ON - Length is measured in Beats
- Musical Mode OFF - Length is measured in Seconds
In this Example four Tracks recorded the exact same audio (so each Track would have its own Audio File) for 2 bars at 120 BPM. Notice there are two Ruler Tracks - the top is in Seconds and the lower is Bars & Beats. All of the Events start on Bar 4 and also at 6 seconds and they end at Bar 6 and 10 seconds. So at 120 BPM all the Events are 2 Bars long and also 4 seconds (10-6) long.
The 4 Tracks are set to all the possible combinations of Timebase and Musical Mode, which is indicated by the Track and Event names. If the Tempo is changed to 130 BPM it effects each of the Events differently based on their Timebase and Mode settings.
Tracks 1 and 3 are both set to Musical Timebase and they both start on Bar 4, although that no longer occurs at the 6 second mark. Track 1’s Audio has Musical Mode enabled so it is still 2 Bars long - but instead of 4 seconds it takes about 3 and a half to play at the faster Tempo. But Track 3’s Audio has Musical Mode disabled so it retains its original 4 second length.
Tracks 2 and 4 are both set to Linear Timebase and continue to start at 6 seconds but no longer Bar 4. Their Musical Mode settings give the same results as Tracks 1 and 3. Track 2 is 2 Bars long while Track 4 is 4 seconds.
When Cubase is making tempo adjustments it bases all its calculations on the Tempo value shown for an Audio File in the Media Pool. If this is incorrect things can move about in unexpected ways. Cubase tries to figure out the proper tempo, but on occasion fails - especially when loop recording within Cubase or importing. So after a Tracking Session make sure the Tempo is set correct before moving on. The order matters too - fix the Tempo before enabling Musical Mode.
