Each track has a volumn contrio which is a small box that shows a number between 0 and 127 and has up and down arrows to increase or decrease the setting. 127 represents as loud as it can go, 0 is mute and everything in between is in between. you can set the audio up as loud as needed if this is not enough then reduce the volumn of the other tracks.

There are also pan (right and left) and I think Reverb and echo. contorls. So you can adjust where in the sound space the various instrument are related to one an other and the audio track.

The controls relate to the selected track.

HTH.
