About “Setting Prohibited.”
Four bits from NT3 to 0 are used to specify the pitch. The bit assignment is as follows.
As the sound source section can simultaneously generate sounds in 4 parts, set the part of a note by using CH1 and 0
bits.
This bit is used to set ON/OFF of Vibrato function for each note: “0” for OFF and “1” for ON. The vibrato frequency
is 6.4 Hz and the modulation depth is ±13.47 cent.
Note that Vibrato function becomes OFF when VIB bit of timbre data ($10-2Fh) is “0.”
Although LSI never hangs, unusual sound may be generated. Never set it.
