EDIT-EG 4. EG The EG function sets up the sample's envelope generators (EGs). The envelope generators determine how sound develops over time, both while the note is held and after it is released. The A5000/A4000 offers three different EGs: an amplitude EG, a filter EG, and a pitch EG. • The [COMMAND/EXIT] button gives you rapid access to a number of helpful commands while you are working with this function. For example, you can use the [COMMAND/EXIT] button when you want to save your edit results to disk, or when you want to cancel your new changes and restore the previously saved data. Press the [EDIT] button and then the [F4] Button to go to the EG functions. 3 display pages are provided: AmpEG (Amplitude EG), FilterEG (page 138), and PitchEG (page 140). • See the "Basic Operation" section on page 78 for details on switching between display pages. Amplitude EG [EDIT] Button → [F4] Button → Knob 1 to select "EDIT-AmpEG" This page sets up the AEG (amplitude envelope generator). The AEG determines how the sound level (amplitude) develops over time. Development begins at Note On, and terminates when the sound dies out. The envelope is defined by four settings, as illustrated below. Cursor q (Amplitude EG Rate/Level) Cursor q Turn action Press action Knob 1 Cursor/Page Tree View Knob 2 AEG Attack Rate QUICK...

[ Press] Tree View Calls the Tree View display (page 83). Knob 2 [ Turn] AEG Attack Rate Determines the rate at which the sound reaches maximum level from the initial Level 0 (note-on). The higher the value, the faster the attack. [Range] 0 - 127 • If the AEG Attack Mode (Cursor w, Knob 4) is set to "hold," this parameter determines the length the maximum level is held (actually the inverse of the value - the higher the value the shorter the hold time, page 138). [ Press] QUICK... Calls the quick entry menu (page 83). Knob 3 [ Turn] AEG Decay Rate This value sets the decay rate: the rate at which the sound drops from its maximum amplitude to its "sustain" level. Higher values produce faster decay. [Range] 0 - 127 • Note that this setting is meaningless (there is no decay period) if the AEG Sustain Level (Knob 4) is set to 127. [ Press] QUICK... Calls the quick entry menu (page 83). Knob 4 [ Turn] AEG Sustain Level This value sets the sustain level. The sustain level is the steady level that begins when decay is completed, and continues until Note Off occurs. [Range] 0 - 127 [ Press] QUICK... Calls the quick entry menu (page 83). Knob 5 [ Turn] AEG Release Rate This value sets the release rate: the rate at which the amplitude drops from the sustain level to zero following Note Off. Higher values produce faster release. A setting of 127 causes sound to stop immediately when Note Off occurs. [Range] 0 - 127 [ Press] QUICK...
