How do I add an SF2 to SeeMusic 3.4 on Mac?

1. In Media Settings, click the MIDI Settings button.

2. You will see a button with the current soundfont name, which is "grand piano.sf2" by default.

3. Click this button to open up the Soundfont settings dialog

4. Click "Import File", and import the .sf2 file you would like to use.
