This article introduces how to play audio using the UE function.
*For information on the sequencer function, please see the Unreal Engine official homepage.

Add sequence assets

To use sequencer functionality, you need to Add a sequence asset containing sequencer data.

Add track to sequencer

Add Atom Track from the track Add button on the sequence editor.

Press the Add Section button on the Atom track, select the Cue sheet, and then select the Cue.

When you select a sound Cue, a section containing the selected sound Cue will be Add to the Atom track.

About audio playback control

Playback start timing

The audio will start playing at the "start of section range" timing.
You can adjust the audio playback timing by moving sections.

Playback Close timing

Audio playback will Stop at the following timings.

Close of section range

You can change the playback interval by moving the edge of the section.

change Volume / Pitch

By expanding the Atom track, you can Add action Key for Volume and Pitch .
By Add this, you can change the Volume and Pitch even while the sequencer is playing.
It is also possible to change the Volume and Pitch values between action Key over time.

Adjust the amount of change between action Key

Open the Curve Editor from the Sequence Editor.

Select the parameter whose change you want to adjust.
The set action Key is View on the graph.

The following settings can be change by moving the action Key View on the graph.

Action Key position
Change value of set parameters

You can also adjust the amount of parameter change by changing the curve between action Key.

Q&A I encountered an issue where the Pitch did not change.

change the Pitch is change the frequency of the audio.
By Default , the CRIWARE UE plug-in is set to support frequencies up to 48kHz.
Therefore, if the maximum frequency is exceeded when change the Pitch , the change will not be processed.
Please refer to Manual for how to set the maximum frequency.
