Audio Playback

Flat integrates a great playback that interprets your sheet music directly in your web browser, without any plugins. Discover here how to use it, change the volume, the instruments' reverb, swing and use our metronome.

Implementation notes

Our goal is to provide a good trade-off between performance and interpretation quality, so it can work well even with a low amount of memory (you might not have the best experience with a large number of instruments).

At this time, most of the notations are interpreted, except:

Use the Playback

To play your composition, click on the play button on the top of the editor. While the playback is active, you will be able to stop, pause and resume the playback at will, and to restart from the beginning of the score using the 3 buttons displayed in place of the initial play button.


Change the volume and reverb

You can find how to change the volume and reverb for a score on our dedicated help page.

Change the playback speed

You can find how to change the global playback speed on our dedicated help page.

Enable the swing

The swing includes the notation and the playback interpretation. Discover how to use it in our dedicated help page.

Does the Crescendo and Diminuendo affects both part of a piano score?

Like all the dynamics on Flat, they only affect the stave where they are added.
