Note: BPMCounter also detects tempo variations in the signal and tries to analyze them
accurately. If the LED starts flashing during playback, this indicates that BPMCounter
has detected a tempo that has deviated from the last received (or set) tempo. As
soon as a new, constant tempo is recognized, the LED is solidly lit and the new tempo
displayed.
• :2 and x2 buttons: Set the displayed tempo to half or double the analyzed rate.
MainStage Correlation Meter
Correlation Meter: Displays the phase relationship of a stereo signal.
• A correlation of +1 (the far right position) means that the left and right channels
correlate 100%—they are completely in phase.
• A correlation of 0 (the center position) indicates the widest permissible left/right
divergence, often audible as an extremely wide stereo effect.
• Correlation values lower than 0 indicate that out-of-phase material is present, which
can lead to phase cancelations if the stereo signal is combined into a monaural signal.
Correlation Meter parameter
• View pop-up menu: Choose a Horizontal or Vertical display and set a size.
Note: You can also set a size by dragging the lower corners of the plug-in window.
MainStage Level Meter
Level Meter: Displays the current signal level on a decibel scale. The signal level for each
channel is represented by a blue bar. Signals (above the target level) approaching the 0 dB
level are represented by a yellow bar. When the level exceeds 0dB, the portion of the bar
above the 0dB point turns red.
Stereo Level Meter instances show independent left and right bars, whereas mono
instances display a single bar.
