VIB : Vibrato
This function is used for setting the vibrato function on or off. Use "0" to set it off and "1" to set it on.
The vibrato frequency is 6.4Hz and the modulation rate is ±13.47cent.
EGT : Envelope waveform type
This function is used to select the type of the envelope waveform.
Use "0" for the damped sound and "1" for the sustained sound.
Shown below are the waveforms for the damped sound and sustained sound.
AR3 - AR0 : Attack rate setting
"Attack rate" refers to the time from start of the sound generation (-48dB) until it reaches the maximum volume (0dB).
The table on page 15 shows the settings by the time required to reach 0dB from –48dB.
DR3 - DR0 : Decay rate setting
The decay rate refers to the damping time required to reach the sustain level (SL) from the maximum volume level
(0dB). The table below shows the settings by the time required to reach -48dB from 0dB.
RR3 - RR0 : Release rate setting
The release rate is defined differently for the damped sound and the sustained sound.
In the case of the damped sound, it means the damping time from the sustain level to the end of the sound length.
The sound is damped in 286ms (time to reach -48dB from 0dB) after the end of the sound length is reached.
In the case of the sustained sound, it means the damping time from the end of the sound length.
