ESSENTIAL PROCEDURES 2. Select a Sample To Edit If the sample you want to edit isn't already selected (the sample name appears at the bottom of the window in the upper left corner of the display), press Knob 1 (TREE) to see a list of the available samples, use Knob 2 to select the desired sample, then press Knob 1 (PARAM) again to return to the "EDIT-AmpEG" display. You can play the selected sample by pressing the [AUDITION] button. 3. Set the EG's Attack, Decay, Sustain Level, and Release When the top function line of the display is highlighted, use Knobs 2, 3, 4, and 5 to adjust the amplitude envelope generator's attack rate, decay rate, sustain level, and release rate parameters, respectively. Attack Rate DecayRate SustainLevel ReleaseRate This parameter produces a faster or slower attack by determining how quickly the sound will reach maximum level when a note is played. The higher the value the faster the attack. The way you set the "AttackRate" parameter can significantly change the character of the sound. If you apply a slow attack to a sample that normally has a fast attack - a piano or plucked string, for example - the result might sound more like a violin or some type of synthesized electronic sound than the original instrument. The way this parameter works also depends on the "AttackMode" parameter setting (discussed in the next step). This parameter determines how rapidly the sound will decay to the sustain level (see below) after the maximum attack level has been reached. It will have no audible effect if the "Sustain Level" parameter (below) is set to its maximum value. While the other three amplitude envelope generator parameters affect rates, the "SustainLevel" parameter actually sets the level at which the sound will be sustained while a note is held. Setting this parameter lower than its maximum value can emphasize the initial attack/ decay portion of the envelope, producing sounds which have a pronounced attack with a more subdued sustain. The speed at which the sound drops from the sustain level to zero after a note is released is set by this parameter. q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q A5000/A4000 • Chapter 2 Sampler Basics & Essential Procedures 51
