[MENU] 1:Level&Rate [ENTER/YES]
The SY85’s main AEG (Amplitude Envelope generator) has five individually
programmable rates and two levels for exceptional envelope programming flexibility.
Next to the fundamental waveform used, the amplitude envelope is one of the most
important factors determining the overall sound of a voice.
Atk/Hld (Amplitude EG attack/hold mode)
Range: atk, hold
Controls: [CS1], [-1] [+1], Dial
The “Atk” and “Hld” mode settings affect the initial attack of the sound,
determining how the amplitude envelope begins. In the “Atk” mode, the enve-
lope begins from zero level, reaching the maximum AWM level at a rate deter-
mined by the R1 (Rate 1) parameter. In this mode there will always be a slight
delay between the initiation of a note and maximum level.
R1 … RR, L2 … L3 (Rates & levels)
Range: 0 63
Controls: [CS2] [CS8], [-1] [+1], Dial
The following diagrams illustrate how the AEG rate and level parameters
determine the overall shape of the amplitude envelope.
