This feature allows you to manually specify the Beats Per Minute (BPM) or tap the space bar in time with the beat until a new BPM is found. Please note that the Automatic BPM calculation uses the range of 70.0 to 180.0 when determining a tracks BPM to reduce calculation time. If you would like to use a BPM value outside this range, it will need to be manually set. The maximum BPM allowed is 240.0.

Waveform Windows

These windows give an illustration of what how the BPM values will appear if they were applied to the current track. You can use mouse wheel to zoom in/out waveform for more accurate beat offset adjustment.

Jump To Start

Same as the play controls variation.

Play

Play this track in headphone, you may need to setup the headphone settings, see Options ~ Audio. Please note that the track will automatically start playing if the Tap Tempo feature is used.

Pause

Same as the play controls variation.

BPM Offset Click

If this button is on and you click on the wave, the location of the click will be set as the start of the BPM for the track. If the wave is dragged, the BPM Offset will be dragged. If this button is off, the position of playback will be changed instead. So a click or a drag on the wave will seek the position.

BPM Update

Clicking on this button will update the wave windows based on the current values of the BPM and BPM Offset.

Edit BPM Offset

The BPM Offset is the distance to the first beat from the start of the track. The BPM scan will set this value automatically once the calculation is finished. However, you can also adjust it by entering a value manually. The sample rate used by Zulu is 44100 so a single sample is 1/44100 of a second.

Edit Beats Per Minute

This field allows you to designate a custom BPM value for the particular track. If Zulu has made an incorrect analysis of the BPM, you can set the BPM to a more accurate setting. Press enter to apply the changed value.

Scan for BPM

If you have a specific tempo you would like to use for the track, you can simply type the BPM in yourself and Zulu will use that number when generating the beat markers. The rescan button prompts Zulu to scan the BPM for you again (in case you typed in an incorrect BPM and you want to go back to the calculated value).

Tap Tempo

Tap tempo works best if you play a track in the background and tap the space bar in time with the beats of the music. Each time you hit the space bar the BPM will change according to the timing of your taps, the longer you tap for, the more accurate the BPM becomes. As you tap you will notice that the BPM will stabilize around a particular number. This is your generated tap tempo BPM and is normally accurate to within one second of the actual BPM. Please note that if the spacebar is not pressed within 15 seconds then the BPM will be reset on the next press.

Tip: If you want unscanned (as in the BPM has not been set yet) tracks to load faster into Zulu's decks you can use the Edit BPM feature to scan the track before it is loaded. This allows Zulu to load the track instantly as it does not have to scan the BPM again.

Tip: A good way to test if a BPM is "correct" or not is to loop a few beats using the beat loop feature. If the loop sounds seamless (ie you cannot tell it is looping, the music sounds continuous) then that indicates that Zulu's beat markers are correctly placed and the BPM is correct.
