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.

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.

Gain Change

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

Tools 3

This submodule contains the digital processing tools listed below.

Gain Change: Alters the level of all or part of a sample.

Compression: The compressor dynamically changes the gain of the sample based on the amplitude envelope of the sample. This is a non-real- time implementation of a full featured dynamic range compressor.

Parametric Equalization: This is a digital (non real-time) implementation of a one band parametric EQ, with +12 dB boost or -48 dB of cut and completely variable frequency and bandwidth controls.

FIR: Phase-linear Lowpass, Highpass, and Bandpass filters with extremely steep cutoff slopes and Q.

Aphex Aural Exciter: This function adds brilliance and “cut” to a sample, helping it to stand out in a mix. The Aphex Exciter works by adding high order harmonics related to the source material.

Gain Change alters the level of all or part of a sample.

v To Change the Gain of 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 Gain Change using the Data Entry Control, INC/DEC keys, or numeric keypad.

3.Press the Tools 3 function key (F4). Another row of function keys appears.

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