☦ With God's help, the "Anna Regent" application appeared.
💙 In the application you can:
📣 Adjust the volume of each part.
🎶 Turn on and off parts individually.
🎧 Listen to every part.
🎵 Sing your part to any of the parts.
🎹 Listen to the singing on the piano.
🎼 One, two, three and four parts will be included at the same time.
🎤 The parts are recorded separately. When one party is playing, the others cannot be heard.
