3.14 ATTB Command
Command to set the cross fade level for the vibrato function on/off by adding two-byte data.
When the lower 4 bits of the data are set to 2000H, the attenuator level is 0dB. The upper two bits
are the attenuator time constant selection bits. These bits select the soft mute time constants.

Note 9: At a reset, the initial values are DSB
= 0H (23 ms) and ALB [13:00] = 2000H (0dB).
The values are set in the same way as the settings for the ATTA command.
3.15 KEYCON2 Command
Command to set the independent key control right channel or to set the vibrato function by adding
two-byte data.
Because the initial reset sets ENA to “L”, L/R common key control by KEYCON is enabled at an
initial reset.

Note 10: At a reset, the initial values are D1
= D2 = 0H.
ENA: Set to “H” when using independent key control or vibrato.
VIB: Set to “H” when using the vibrato function.
K2R [11:00]: When KEYCON2 is used for independent key control, these bits set the key control rate.
When KEYCON2 is used to select the vibrato function, these bits set the step value that
determines the vibrato cycle.
