What is a soundbank?
A soundbank is a file that contains a collection of instrument sounds. These sounds are used by the synthesizer to play the notes in a MIDI file. The app comes with a default soundbank, but you can replace it with a custom one.
Configuring soundbanks
In the settings tab, under Playback, click the Soundbanks option.
To add a soundbank, click the Add soundbanks button and select a .sf2 or .dls file from your computer,
or drag and drop the file onto the soundbanks list.
To remove a soundbank, click the button next to the soundbank you want to remove.
You can select which soundbank to use on the home tab. You can also choose a soundbank when recording a video.
Bug
The app may sometimes incorrectly use the wrong sounds from the soundbank. This is due to a bug in the Java Sound API, which the app uses to play MIDI files. If you encounter this issue, use a different soundbank or MIDI device.
In the settings tab, under Playback, click the Soundbanks option.
To add a soundbank, click the Import button and select a .sf2 file.
To remove a soundbank, click the next to the soundbank you want to remove.
You can select which soundbank to use on the home tab.
