BPM Counter in MainStage
BPM Counter analyzes the tempo of incoming audio in beats per minute (bpm). The detection circuit looks for any transients, also known as impulses, in the input signal. Transients are very fast, nonperiodic sound events in the attack portion of the signal. The more obvious this impulse is, the easier it is for BPM Counter to detect the tempo.
Percussive drum and instrumental rhythm parts, such as basslines, are suitable for tempo analysis, whereas pad sounds are unsuitable candidates for tempo analysis.
To add BPM Counter to your concert, choose Metering > BPM Counter in a channel strip Audio Effect plug-in menu. See Add and remove plug-ins in MainStage.
BPM Counter parameters
BPM Counter: Analyzes the tempo of incoming audio in beats per minute (bpm). Click the numerical display to reset.
The numerical display the current analysis status. If the LED is flashing, a tempo measurement is taking place. When the LED is continuously lit, analysis is complete, and the tempo is displayed. The measurement ranges from 80 to 160 beats per minute. The measured value is displayed with an accuracy of one decimal place.
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 stops flashing and the new tempo displayed.
:2 and x2 buttons: Set the displayed tempo to half or double the analyzed rate.
