BPM Counter
The BPM Counter is a useful plug-in that analyzes the tempo of an audio track and
displays it as a numeric value. As soon as the plug-in is inserted in a track, the
intelligent detector circuit analyzes the dynamic events in the signal.
The detector circuit looks for any transients in the input signal. Transients are very fast,
non-periodical sound events in the attack portion of the signal. The more obvious this
impulse is, the easier it is for the BPM Counter to detect the tempo. As a result,
percussive drum and instrumental rhythm tracks (basslines, for example) are very well
suited for tempo analysis. Pad sounds are a poor choice.
The LED shows the current state of the analysis process. If the LED flashes, the circuit is
performing a tempo measurement. When lit, analysis is complete, and the measured
tempo is displayed. The measurement range is from 80 to 160 beats per minute and the
measured value is displayed with an accuracy of one decimal place.
The BPM Counter also detects any tempo variation in the signal and tries to analyze it
accurately. If the LED starts flashing, the BPM Counter has detected a tempo variation
that has deviated from the last received (or set) tempo. As soon as a new, constant
tempo is measured, the LED will be solidly lit.
Clicking the LED resets the BPM Counter.
Match EQ
The Match EQ offers an additional sidechain input that is used for Template Learn
mode, if active.
Mix Slider of Platinum Verb and Tape Delay
The user interface of the Platinum Verb and Tape Delay have been enhanced: The Dry
and Wet sliders were moved from the 001/011 view to the Editor view, replacing the Mix
slider (which is still available in the 001/011 view).
