Beat Munger Controls

Analysis Results: This field displays the analyzed tempo and number of beats in the sample. The sample may contain any number of beats and this number will also be displayed in the Loop Controls field.

Tempo Adjust: Adjusts the Tempo of the loop (you knew that) without altering the pitch. The Tempo field defaults to the tempo determined from the analysis.

Swing Adjust & Control: Swing can be modified in both a positive and negative (anti-swing) direction. Negative swing can actually remove swing from a groove.

With Swing set to “Norm” and “0%”, each quarter note is weighted so that the first eighth note takes up 50% of the quarter note and the second eighth note takes up the other 50%. When the swing factor is changed to a positive amount, the first eighth note takes up more of the time and the second eighth note gets the rest. Negative swing lengthens the time spent on the second eighth note

There are four different swing controls.

Fast . . . . . . . . . . . Swings within an eighth note

Norm . . . . . . . . . Swings within an quarter note

Slow . . . . . . . . . . Swings within a half note

Loop Boundary Control: These controls allow you to redefine the start and end points of the loop. For example, you could remove the first beat of a loop or the last bar of a four bar loop. The default setting of this field is determined by the length of the loop.

Downbeat Selection: Sometimes Beat Munger makes a mistake when choosing the proper downbeat and may choose an upbeat instead. This control allows you to correct the mistake. Depending on the source material, several choices may be provided. Use this feature in conjunction with the metronome. You can also use this control to deliberately place the accent on other beats.

Stereo samples use more CPU resources than mono samples in real-time audition mode.

Note: Final rendering (i.e. pressing OK to actually change the sample data) will always be processed correctly even if real-time playback is choppy.

Process Adjust Controls:

Grunge controls the splice crossfade length. This control can make the sound rough, smooth, or “flangy”. Smaller values produce shorter crossfades. Longer crossfades use more CPU resources.

Comb adjusts the distance between splices. This control can be used to keep the groove rhythmically tight, produce comb-filter effects, or create echo-type effects (depending on the source material). Low values can keep the sound from becoming too “fluttery”, especially when shifting the tempo down, but consume more CPU resources.

8th Note Grid: The 8th note grid is a representation of two bars of 8th notes. Individual 8th notes can be turned Off or On. If the loop is longer than 2 measures, the 2-bar grid settings will also be applied to the following measures. The diagram below shows how the 8th note grid corresponds to 8th notes and quarter notes.

The time signature can be altered by removing notes from the loop. The diagram below shows a 2-bar loop in 4/4 time being changed into 7/8 time.

Metronome Level: Adjusts the volume level of the metronome. The metronome is useful in determining the proper downbeats.

CPU Meter: The CPU meter shows the amount of CPU power being used while auditioning in real-time. Extreme settings of the controls with stereo samples may tax the CPU to the point where the audio quality is affected. The CPU meter is a barberpole which moves at a constant rate when everything is running normally. If you see the barberpole stutter or freeze, you may want to select more normal control settings.

Beat Munger

O Sometimes the Munger misses the last beat of a looped, 1 bar groove. To correct this problem, Copy the loop and Paste to the end of itself. Truncate the loop with Beat Munger to get a perfect 1 bar loop.

Play Button: Starts real-time loop audition.

Stop Button: Stops real-time loop audition.

Re-Analyze Button: Sometimes the analyzer will lock onto a harmonic of the tempo, or some other polyrhythmic element in the groove, and give the wrong answer for the tempo analysis. The ReAnalyze button allows you to enter your own estimate of the true tempo. Beat Munger will use your tempo data to resynthesize the groove.

OK Button: Once you are happy with the settings, press OK to actually process (and replace) the sample. The metronome will not be heard in the processed sample and the sample will always be rendered correctly even if the real-time audition was of poor quality. The sample will be set to loop its entire length. UNDO is available to restore the original sample if you’re not happy with the result.

“Signal Appears to be Cropped” message

Congratulations! You’ve already trimmed your sample groove to loop perfectly. This screen is merely informing you that the sample is perfectly sized to loop.

Press Yes if you want to use the sample length for the phrase length.

Press No if you want Beat Munger to determine a tempo.

Undo

Have you ever wanted a time machine so that you could go back and undo a mistake? This function may be the next best thing. Whenever you

perform a sample edit function, the original version of the sample will be backed up if “Undo/Redo” is enabled (Master, Miscellaneous). The original sample is placed on the clipboard and can be instantly restored by pressing Undo.

v To Restore a Sample to its Original State

1. Press the Sample Edit key. The LED illuminates and the main sample edit screen appears.

2. Press the UNDO! function key (F6). The original sample will be restored and the processed sample will be stored in the clipboard.

v To Compare a Processed Sample with the Original Sample:

1.Press the Sample Edit key. The LED illuminates and the main sample edit screen appears.

2.Press the UNDO! function key (F6). The original sample will be restored and the processed sample will be store in the clipboard.

3.Press the REDO! function key (F6) again. The processed sample will be restored and the original sample will be stored in the clipboard. You can continue switching back and forth until you decide which sample you want to keep.
