Level controls the software's master output level.
MPC Renaissance users: The software's Level knob controls the volume
level of the audio before the MPC Renaissance's Main Volume dial. The
audio will then be sent out of the Stereo Outs on the rear panel.
The Vintage display directly below the output level meter indicates the
selected emulation mode.
MPC Renaissance: Press the Vintage Mode button to switch between the
different audio quality emulations. You can select to emulate the particular
sonic qualities of the MPC3000, the MPC60, Other and of course no
emulation (no LED will be lit).
