Solution: The control is designed to compensate for minor differences in balance and does not completely mute either channel.

•Problem: There is no volume control for MIDI sound in the Volume Mixer window.

Solution: Use the hardware volume control. This is because the built-in synthesizer software does not support the control.

•Problem: The sound cannot be turned off completely even if you set the Master volume control at minimum.

Solution: You still can hear some sound even though you have set the Master volume control at minimum. To turn off the sound completely, go to the Master volume control and select Mute speakers.
