To write with multiple voices first select which voice that new music is written to.

To select the voice go to the notation tab on and click voices, from the menu select which voice you want new notes created on. Alternatively press the shortcut Ctrl + number keys 1 - 4. It's important to remember to place rests in areas of silence on each voice which is resting.

If you want to hide a voice for clarity, you can hide/show a voice from the menu Voices.

The Display option in the menu Voices allows you to show/hide a voice on the score page.

The Mute option in the menu Voices allows you to make a voice silent if you do not want to hear it in playback.

Initial activated voice of a score is voice 1, which means inserting notes will be placed in voice 1. If you want to insert notes in voice 2 after finishing some notes in voice 1, you can activate voice 2 by clicking "Select Voice 2" on the Voice button under Notation tab. In addition, you can change voice of existing pitches by right-click context menu without change of activated voice.

Note: The current activated voice cannot be hidden or mute.
