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

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.
