The [GAIN] on the computer screen does not change when the [GAIN] control is operated.

The gain is adjusted automatically when a track is loaded.

At this time, if the position of the knob on this unit and the position of the knob on the computer screen are not the same, the [GAIN] cannot be adjusted even by operating the knob on the unit. It can be adjusted once the knobs have been set to the same positions.
