Pitch Change

The following table lists the sample type choices.

deep

Predominant deep bass (to 14 Hz)

bass

Predominant bass (to 20 Hz)

mid-1

Average source material

mid-2

Average source material (high-mids)

high

Source material with high frequencies

tight

Maintains time accuracy - Drum loops

broad

Low bass energy but critical highs

broad-smooth

Both high & low freq. - Smooth output

difficult

Inharmonic or broadband material

noisy

Non-pitched - Sound Effects, etc.

tight-smooth

Rhythmic accuracy - Use small ratios

x-smooth

Rhythmic accuracy - Use small ratios

 

 

7. Press OK to process the sample or Cancel to cancel the operation.

Pitch Change

This function is the exact opposite of Time Compression in that it changes the pitch of a sample without changing the time. The maximum amount of pitch change is ±1200 cents (± one octave).

v To Change the Pitch of a Sample:

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

2.Select the sample you want to process using the Data Entry Control, INC/DEC keys, or the numeric keypad.

3.Press the Tools 4 function key (F5). Another row of function keys appears.

4.Press the PitchX function key (F4). The following screen appears.

5.Enter the desired pitch change interval in cents using the Data Entry Control, INC/DEC keys, or the numeric keypad.

6.Select the general type of sample to be processed.

Bit Converter

If you are not happy with the results of Pitch Change, simply Undo, then choose another algorithm.

O Tip #1: You can create silent samples by setting the bit resolution to zero.

Tip #2: The Bit Converter can be used to optimize samples for playback on 8 bit devices.

The choices are:

deep

Predominant deep bass (to 14 Hz)

bass

Predominant bass (to 20 Hz)

mid-1

Average source material

mid-2

Average source material (high-mids)

high

Source material with high frequencies

tight

Maintains time accuracy - Drum loops

broad

Low bass energy but critical highs

broad-smooth

Both high & low freq. - Smooth output

difficult

x-smooth

Rhythmic accuracy - Use small ratios

Bit Converter

For those who want to return to a simpler time when samples were eight bits (or less), we offer the Bit Converter. The Bit Converter takes your pristine 16 bit samples and transforms them into any bit resolution you select. Ever wonder what a 1-bit sample sounds like? Find out with the bit converter. You cannot increase the bit resolution once it’s been removed.

v To Change the Bit Resolution of a Sample:

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

2.Select the sample you want to process using the Data Entry Control, INC/DEC keys, or the numeric keypad.

3.Press the Tools 4 function key (F5). Another row of function keys appears.

4.Press the BitCnv function key (F5). The following screen appears.

5.Enter the desired bit resolution using the Data Entry Control, INC/DEC keys, or the numeric keypad.

6.Press OK to process the sample or Cancel to cancel the operation.

Beat Munger

 

Beat Munger

 

Beat Munging is a new real-time DSP tool that analyzes your drum loops

 

and phrases, automatically determines the tempo, and then perfectly loops

 

the sample for ultimate groove preservation. Beat Munging also allows you

 

to change the loop’s time signature (i.e. from 4/4 to 7/8), tempo, swing

Note - Beat Munger is

factor, and individually manipulate beats within the loop, all in real-time.

Through complex spectral analysis, the Analyzer determines the high

only available on Ultra series

points in the energy curve (the beats), locates and remembers the location

Emulators because it requires

of transients in the signal, and extracts the tempo (displayed in the Analysis

mucho processor horsepower.

Results field). Once the analysis is complete, the main Beat Munger screen is

 

displayed. Pressing Play allows you to hear the loop. Adjust the controls

 

and hear the changes in real-time (it may take a second or two to hear the

 

results after moving a control, depending on the source data or the position of the

 

loop). When you’re satisfied with the settings, press OK to process the actual

 

sample data. The sample will be backed-up for UNDO and the newly

 

processed sample will REPLACE the source sample. Back up the original

 

sample first if you want to keep it!

v To Beat Munge:

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

2.Select the sample you want to process using the Data Entry Control, INC/DEC keys, or the numeric keypad.

3.Press the Tools 4 function key (F5). Another row of function keys appears.

4.Press the BeatM function key (F6). A spectral analysis will be performed to find the tempo and beats. The following screen appears.

If you try to process a sample without beats, a pop-up window informs you that the “Sample has no groove!”

5.Press Play to hear your looped groove.

6.Adjust the parameters using the Data Entry Control, INC/DEC keys, or the numeric keypad and hear changes in real-time.
