You can add backing tracks to your exercises in SongCreator and use your publicly available direct links to sound files, as well as cloud services such as SoundCloud, Dropbox, and GoogleDrive. You can also use your YouTube video as a backing track by simply pasting a direct link to the specific video you want to use.
In order to start streaming a track, go to the relevant website/cloud service, and copy the http link for the track. Note: If you're using SoundCloud to upload the backing track, make sure the end of the link is the name of the song you want to upload. Here's a good example.
Go to the Yousician SongCreator either by creating, uploading, or editing the song you would like to add a backing track to. Tap/click on Tap here to add your backing track and paste or type the link to the text box in the screen that opens.
SongCreator will automatically load the backing track and analyze the audio.
Once the track is ready to be played back in Yousician, you will see the waveform of the audio track over the tab staff.
Once the waveform is rendered, you will see that the playback starts right from the beginning of the exercise. If the audio begins from the first measure of the exercise, and if you have the tempo correct, the audio will be synchronized to the exercise. However, in reality, most tracks begin slightly later, and have small tempo variations, which make it necessary to have an alignment between the audio and the exercise. In order to do that, make sure you have the exercise data, i.e. the notes, already typed in; you can either enter the notes in the SongCreator, or enter them beforehand using a third-party tool and upload it to Yousician. When you have the exercise and backing track ready, click/tap on the Backing track icon on the top pane and choose Auto sync to automatically synchronize the two. When the alignment is done, you will see that the waveform moves to the correct place in relation to the notes.
If you are not happy with the automatic synchronization of the sound, it is also possible to edit it manually by moving the whole backing track. In order to do that, tap/click on the Backing track from the top pane, and toggle on Manual sync. When the backing track waveform turns green, you can drag the waveform to fit the exercise. To get the best results, make sure that the exercise is in the same tempo as the backing track.
To check the synchronisation, click Play to listen to your track.
When you are done editing check step 5 on how to save the song.
Similarly, you can also create a copy of an existing song and replace the backing track following these steps.
