Using the Mixer
The Mixer allows the volume of each track to be adjusted.
There are 16 MIDI channels, and the volume of each can be raised or lowered by touching and dragging a slider control. A track may also be muted by touching the number at the bottom of each slider. Muted tracks are displayed in red.
Note that changes made on this screen will only be saved if the adjustments are made when the song is not playing. This is because the MIDI file being played may contain events that change the track volume, and only the initial volume is set.
