SL3 - SL0 : Sustain level setting
The Sustain Level, in the case of decaying sound, is the transition level from the Decay Rate to the Release Rate, and
in the case of sustained sound, is a level held.

TL5 - TL0 : Total level setting
This function is used to set the envelope level.
TL
Weighted bit (dB)
SUS : Sustain On/OFF setting
"0" : OFF
"1" : ON
The Release Rate changes to "6" (2.29s) when the sound length comes to the end.
WAV : Waveform selection
The modulator and carrier can generate a sine wave; however, can generate a half-wave rectified waveform by setting
this bit. Setting this bit allows creation using wider timbres.
"0" : Sine wave
"1" : Half-wave rectified waveform of a sine wave.
WAV=0
FL2 - FL0 : Feed-back setting
This function is available only for the operator of Modulator. These bits specify the feedback modulation depth.
Be sure to set "0" to the operator of the carrier side. This is effective function for generating the strings timbres.
