Timeline
The timeline controls the adaptive scrolling engine introduced in Song One 9 and allows you to perform the following actions:
Auto-scroll songs within an exact duration regardless of the device's screen size and the song's zoom level.
Program the song's scrolling speed and sync the scrolling position with the audio backing track's waveform (in page flip or auto-scroll mode).
Remote control external devices and apps (e.g. ProPresenter) via MIDI note and MIDI queue events added to the timeline. (See MIDI Events and MIDI Queue to learn more.)
The timeline can be accessed when the play mode is active and playback is paused:
Tap/Click on the button with the timeline icon to open the song's timeline window.
Timeline Playback Controls
The length (duration) of the timeline is determined by the song's duration entered in the song info panel. When an audio backing track is added to a song the length is automatically updated to match the duration of the audio track's waveform:
A playhead in the left corner of the timeline indicates the playback position of a song. When auto-scroll is enabled (instead of page-flip) the playhead position will also control the scrolling position of the lyrics.
A red playhead with outward pointing arrows indicates that the timeline/waveform is unlocked during playback.
Swipe the timeline/waveform left or right to change the playback position of the backing track and view a different portion of a song. (The playback of the song does not have to be stopped to reposition the timeline/waveform.)
macOS: Swipe over the trackpad with two fingers to reposition the timeline/waveform.
When performing live the timeline/waveform should be locked to avoid interrupting the playback of the backing track when the screen is touched:
Tap/Click on the playhead's arrows to unlock/lock the timeline/waveform for all songs during playback.
A blue playhead with inward pointing arrows indicates that the timeline/waveform is locked during playback. (The position of the timeline/waveform can still be changed by swiping it left or right when playback is stopped.)
Adding Timeline Events
Events can be placed on the timeline/waveform to alter the song's scrolling position and execute commands during playback. (The playback of the song does not have to be stopped to add events to the timeline.)
Tap/Click on the plus sign above the time display to the left of the timeline/waveform.
The timeline event window will appear:
Customizing Auto-Scroll
You can control the scrolling speed of the native Song One documents by adding section events to the timeline. (The playback of the song does not have to be stopped to add events to the timeline.)
A timeline without section events will scroll the song at a linear speed. Once section events are added to the timeline Song One will auto-adjust the scrolling speed to arrive at each song section at the specified time.
Note: Song One will only move to the next matching section label positioned below the current scrolling position.
When section label events are added to the timeline the scrolling position is controlled via timeline and cannot be manually adjusted (via a bluetooth controller or screen taps).
When section label events are added to the timeline all scrolling speed events other than 'Pause Scrolling' are ignored.
Tap/Click on the location icon at the top of the timeline event window and make a selection from the drop-down menu.
Start the playback of the backing track (or drag the timeline into position by swiping it left or right) and tap/click on the 'Add' button to add the event to the timeline.
Once the section event has been added Song One automatically suggests the next section label from the list:
When the audio backing track has reached the next song section (e.g. Verse 2) tap/click on the 'Add Next' button to add the event to the timeline.
Customizing Page Flip
When page flip is active you can control the scrolling position of native Song One documents by adding section events to the timeline. (The playback of the song does not have to be stopped to add events to the timeline.)
Note: Song One will only move to the next matching section label positioned below the current scrolling position.
The timeline will ignore a section event if the section label cannot be located below the current scrolling position.
See Adding Timeline Events and Customizing Auto-Scroll to learn more about adding section events to the timeline.
Scrolling Speed
You have the option to increase/decrease the scrolling speed once a certain location on the timeline has been reached.
Tap/Click on the speedometer icon at the top of the timeline event window and make a selection from the drop-down menu.
Drag the timeline into position by swiping it left or right and tap/click on the 'Add' button to add the event to the timeline.
Vocal Cues
Vocal cues are used to assist the performers during band rehearsals and live events. Vocal cues are audible in the performers' in-ear monitor system in addition to a click track or a backing track.
Typical vocal cues include:
A count-in to inform the drummer when to start playing,
the first line of the lyrics to support the lead singer,
the name of the upcoming song section to guide the band.
To add a vocal cue to the timeline of a song:
Tap/Click on the speaker icon at the top left of the timeline event window, select 'Vocal Cue' from the menu and type the cue into the text field (e.g. 'Verse 1').
Start the playback of the backing track (or drag the timeline into position by swiping it left or right). Tap/Click on the 'Add' button to add the cue to the timeline at the desired position.
Song One transforms the entered text into speech when the cue marker is reached during the playback. (Note: Vocal cues are executed with a slight delay since the text has to be synthesised.)
Note: Added cue events may later be repositioned by performing a long tap on the event and dragging it left or right.
The time display to the left of the timeline will turn orange while the event is being dragged to indicate the drop position of the event.
Remote-Controlling ProPresenter
ProPresenter is a powerful presentation software created by Renewed Vision. It is used to generate dynamic visuals during live performances and church services. Song One can remote-control ProPresenter via timeline events.
Song One's outgoing MIDI commands are compatible with ProPresenter's default 'MIDI Map' settings. Revert to ProPresenter's default settings as follows:
Open ProPresenter's 'Devices' Settings Window (ProPresenter -> Settings -> Devices) and tap/click on the 'MIDI Map' button.
Enter the number '0' in the top left field of the MIDI Map window and tap/click on the 'Auto Fill' button.
ProPresenter's MIDI Map is now configured to work with Song One's timeline events. Consult ProPresenter's user guide to learn more about the app's MIDI capabilities.
Now you can add ProPresenter's MIDI events to Song One's timeline/waveform to be executed at specific times. (The playback of the song does not have to be stopped to add events to the timeline.)
Tap/Click on the plus sign above the time display to the left of the timeline/waveform.
The timeline event window will appear:
To add a new ProPresenter event to the timeline...
Tap/Click on the MIDI Icon at the top of the timeline event window and make a selection from the 'Control ProPresenter' drop-down menu.
Drag the timeline into position by swiping it left or right and tap/click on the 'Add' button to add the event to the timeline.
Note: Added timeline events may later be repositioned by performing a long tap on the event's icon and dragging it left or right.
The time display to the left of the timeline will turn orange while the event is being dragged to indicate the drop position of the event.
Standard MIDI events that are placed (or repositioned) on the timeline are executed with an accuracy of one decisecond (0.1 second).
To increase the accuracy create a high precision MIDI event by typing in its timeline position in a format that includes milliseconds:
You don’t have to include all digits when entering a time value. An entry of 5.221 is automatically converted to 00:05.221 and the MIDI event is added to the timeline at the corresponding position
