"The Volume Edit module allows you to apply a percentage adjustment to individual instruments on either a show or song basis. To edit specific songs, be sure the song in question is selected in the left 'Current Song' field before entering the Volume module. Note: Volumes settings live within a range of 0-127. Therefore, there are limits to the amount you can increase volume. For example, if an instrument is preprogrammed at a volume level of 100, the most you will be able to increase it is 27% to get to the maximum value of 127. Attempting an increase greater than 27%, in this case, will still result in just a 27% boost, since the setting has already reached its upper limit. Generally speaking, volume adjustments should be kept within a 15-20% range. If you feel you need a very large gain, consider lowering the other instruments instead, so the instrument in question stands out more."
