The FS1R amplitude envelope generator has four individually programmable time and level parameters for
exceptional envelope programming flexibility. Next to the actual waveform of the sound, the amplitude envelope is
one of the most important factors determining the overall sound of a voice.
The following diagrams illustrate how the Time and Level parameters determine the overall shape of the amplitude
envelope.
Higher Time parameter values produce correspondingly longer times. A time setting of “0” will result in an almost
instantaneous transition between the related levels, while a setting of “99” will produce the longest transition
between the related levels.
For the level parameters, a setting of “0” corresponds to the lowest possible level (no sound) while a setting of “99”
produces the highest output level.
The EGTimeScaling parameter allows the overall envelope generator time for the selected operator to be varied
across the entire pitch range. Higher values produce an increasingly longer overall envelope time for notes below
G3, and an increasingly shorter envelope time for notes higher than G3. Please note, however, that the G3 point will
shift in accordance with the settings of the Note Shift parameters (pages 24, 40, 59, 71).
