6 - Sample Edit

DC Filter

_ If the sample sounds clipped after DC Filtering, Undo, then attenuate the sample by 2 dB. Next, DC Filter the sample and Normalize using Change Gain.

Tools 2

This submodule contains the basic digital processing tools listed below.

DC Filter: Removes the DC component from a sample, centering the waveform around the zero axis.

Swap L/R: Swaps the left and right sides of a stereo sample

Stereo<->Mono Conversion: Converts stereo samples to mono and viceversa.

Reverse Sample: Reverses all or part of a sample.

Sample Integrity: Remedies looping problems in imported samples.

DC Filter

Removes the DC component from a sample, centering the waveform around the zero axis. The positive and negative peaks of the sample are expressed in 16 bit samples. Full scale for a 16-bit sample is ±32767. Use the peak values to see how close you are to full scale. If one of the peaks is too close to 32767, DC Filtering may cause the signal to clip. Mean is the DC bias present in the sample. The lower the number, the less bias is present.

v To DC Filter:

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

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

3.Press the Tools 2 function key (F3). A second row of function keys appears.

4.Press the DC Filter function key (F1). The following screen appears.

Swap Left & Right

Swaps sides of a stereo sample or moves a mono sample to the other side.

v To Swap Sides:

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

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

3.Press the Tools 2 function key (F3). Another row of function keys appears.

4.Press the SwapLR function key (F2). A pop up display will ask you to confirm the operation.

5.Press OK to swap the selected sample or Cancel to cancel the operation.

6 - Sample Edit

Stereo <-> Mono

If the sample is stereo, a pop up dialog box will ask you to select left, right or both sides.

Stereo <-> Mono

Converts a stereo sample to mono or a mono sample to stereo. Converting to stereo duplicates the sample on both sides and slightly detunes them. Converting to mono sums both sides of the stereo sample, then divides by two.

v To Convert a Sample:

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

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

3.Press the Tools 2 function key (F3). Another row of function keys appears.

4.Press the S <-> M function key (F3). A pop up display will ask you to confirm the operation.

5.Press OK to convert the selected sample or Cancel to cancel the operation.

Reverse Section

Reverses all or part of a sample.

v To Reverse a Sample:

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

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

3.Press the Tools 2 function key (F3). Another row of function keys appears.

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

The Select Section display controls are identical to the controls in Truncate. See Truncate for a full description of the controls.

O The Start and End points are “remembered” from module to module so that you can perform successive operations on the same section of the sample.

6 - Sample Edit

Sample Integrity

5.Specify the Start and End points for the portion of the sample to be reversed using the Data Entry Control, left/right cursor keys, INC/DEC keys or the numeric keypad.

The left and right cursor buttons will change the start and end points so that they fall on positive zero-crossing points in the waveform. This will minimize clicks in the sound when processing only part of a sample.

6.Press OK to reverse the section or Cancel to cancel the operation.

Sample Integrity

Imported samples may occasionally have slight looping problems (heard as ticks) due to data corruption of the sample header file. This function remedies the problem by reconstructing the sample header.

v To Fix all Samples:

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

2.Press the Tools 2 function key (F3). A second row of function keys appears.

3.Press the Integrty function key (F6). You are asked, “Fix all Samples?”.

4.Press OK to fix all samples in the bank or Cancel to return to the Sample Edit screen.
