Mute
If a track is muted it will not be heard. The only exception is if the track is also set to solo, in which case the mute setting is ignored and only the solo setting is used.
Left clicking or pressing Enter toggles the mute setting of a track. If the Ctrl key is held down, the mute setting of tracks having the same port and channel as the clicked track will be toggled. Use this to mute and unmute all drum tracks with a single Ctrl click.
Ctrl right clicking mutes and unmutes all tracks.
Tip: Pressing M toggles the mute setting for the current track.
