The mixer allows you to change instrument sounds and adjust the volume, panning, reverberation, and chorus for each staff. From the main menu, choose Display → Mixer to show the mixer.
Use the Mute check box to quickly silence certain staves. Alternatively, use the Solo check box to silence all staves, except the staff you mark as "solo".

The sound drop-down menu lists every instrument supported by your current SoundFont .
You can change a staff to be a different instrument. The following method updates instrument sound, staff name, and staff transposition all at once.
Some instruments can change sounds midway in a score. For example, strings can switch to pizzicato or tremolo and trumpet can switch to muted trumpet. The following instructions use muted trumpet as an example, but the same principles apply to pizzicato or tremolo strings.
Every note after the staff text you added now sounds muted. To return to an unmuted sound later in the piece, follow the same guidelines as above except type Open in step 3 and select normal in step 6.
