Clocks & Synchronization

Clocks

Mixbus provides two clocks which display the current position of the playhead. Having 2 clocks is a convenience: for example you can leave one clock showing “musical” time (such as bars/beats) while the other clock shows time in hours:minutes: seconds.

Right-click on a clock to change the mode of the clock. A menu appears with the available options.

*To learn more about clocks in the transport toolbar, visit the Transport Bar section.

*Note: There are several other clocks in Mixbus, such as the Nudge clock and the SMPTE offset clock. These clocks can also be set to any mode, so you can (for example) set the nudge clock to advance in bars:beats instead of minutes:seconds.

Some clock modes have smaller sub-displays which show the current meter/tempo, SMPTE format, or sample rate (in applicable modes).

It is possible to click on a clock and directly enter a time code location directly. Pressing “Enter” will locate the playhead to the new time.

*Tip: you can point at a clock element (minutes, seconds, beats, or whatever) and use the mouse-wheel (or 2-finger scroll on a touchpad) to quickly tweak the value without entering it manually.

Synchronization

Mixbus allows selection of several synchronization sources: Internal, LTC, MTC, and JACK

• Internal: The playhead position is defined by Mixbus; all transport commands come from Mixbus.
• LTC: The playhead position and transport state will be determined from incoming LTC (SMPTE) timecode.
• MTC: The playhead position and transport state will be determined from incoming MIDI Time Code.
• JACK: The playhead position and transport state will be determined from JACK. Transport commands initiated from Mixbus will be applied to all JACK-synchronized programs. (JACK is a third party program, and is not included with Mixbus 3, however, MB3 can utilize JACK if it is installed in your system.)
  

*Note: A list of JACK-aware programs is listed at: http://jackaudio.org/applications

• Time Master (JACK only): Only one JACK-synchronized program can be the “Time master”. When JACK sync is used the timelines of the synchronized programs are located using the sample-clock offset. Since different programs may have different tempo maps, or methods of handling musical time, the “time master” identifies the machine that will define the musical time (bars/beats) position of the song. This is for advanced users only.
