7-2-2. Key Controller Settings
[Relevant coefficients] TRi (address = 1BH), TVi (address = 1EH), nRpR (address = 22H),
KWR (address = 23H), KRigh (address = 24H), KLeft (address = 25H),
KWR-1 (address = 26H), Ks (address = 2EH), VnRpR (address = 47H),
Krmpd (address = 55H), Krmpe (address = 56H)
(1) Key Controller Pitch Ratio
nRpR (D15, ..., D2) is 2's complement format with the decimal point between D14 and D13, and sets the
desired pitch ratio directly. (VnRpR has the same type of setting as nRpR.)
15
nRpR =
∑
Dn
×
2
n–14
n = 2
The expression range for the pitch ratio is: –2.0
≤
nRpR
≤
2.0 –2
–12
but for practical use it is: –0.5
≤
nRpR
≤
1.0
or ±1 octave
Use within a range of ± half an octave is recommended for quality of sound, although this depends on the aim
and the source.
Also, the algorithm is such that allophones are not generated even when the nRpR setting value is changed.
(2) Notes on Key Controller OFF
The pitch does not change when nRpR and VnRpR are set to 0000H (OFF) when the key controller is OFF,
but depending on the internal status during OFF, there is no guarantee that the input value will be output as is.
During OFF, after setting nRpR and VnRpR to 0000H (OFF), set the pitch control section to through status with
the following settings.
Accompaniment controller OFF: Ks = 0000H (OFF)
Voice key controller OFF : Krmpd = 0000H (OFF)
: Krmpe = 0000H (OFF)
