Reso.AMS (Resonance AMS)
[Off, (PEG, FEG, AEG, LFO, KT, EXT)]
Indicates the source that will control the “Resonance (A Res-
onance)” level (
☞p.212 “AMS List”).
Intensity (AMS Intensity) [–99…+99]
Specifies the depth and direction of the effect that “Reso.
AMS (Resonance AMS)” will have on the resonance level
specified by “Resonance (A Resonance).”
For example, if Velocity has been selected, changes in key-
board velocity will affect the resonance.
With positive (+) values, the resonance will increase as you
play more strongly, and as you play more softly the reso-
nance will approach the level specified by the “Resonance
(A Resonance)” setting.
With negative (–) values, the resonance will decrease as you
play more strongly, and as you play more softly the reso-
nance will approach the level specified by the “Resonance
(A Resonance)” setting.
The resonance level is determined by adding the “Reso-
nance (A Resonance)” and “Intensity (AMS Intensity)” val-
ues together.
4.1–1c: B (Filter B)
This will be displayed if “Type (Filter1 Type)” (4.1–1a) is
Low Pass & High Pass.
This filter cuts the low-frequency range that lies below the
cutoff frequency.
By cutting the lower overtones, it lightens the tone.
Frequency (B Frequency) [00…99]
Specifies the cutoff frequency of filter 1B.
■ 4.1–1d: UTILITY
☞“Write Program” (1.1–1c), “Copy Oscillator,” “Swap
Oscillator” (2.1–1d)
4.1–2: Mod.1 (Filter1 Modulation1)
Indicates settings for keyboard tracking which modifies the
tone by modulating the filter 1 cutoff frequency “Frequency
(A/B Frequency),” and intensity settings for the filter 1 EG,
etc.
4.1–2a: Keyboard Track
These settings specify keyboard tracking for the cutoff fre-
quency of filter 1. The way in which the cutoff frequency is
affected by the position of the key (on the keyboard) that
you play can be specified by the Key: “Low” and “High,”
Ramp: “Low” and “High” parameters.
Key:
Specifies the note numbers at which keyboard tracking will
begin to be applied, and set the “Int. to A” and “(Int. to) B”
parameters to specify the depth and direction of the change
applied to filter 1 A and B.
For the range of notes between “Low (KBDTrk Key Low)”
and “High (KBDTrk Key High),” the cutoff frequency will
change according to the key location (pitch).
You can also input a value by playing a note on the key-
board while you hold down the [ENTER] key.
Low (KBDTrk Key Low) [C–1…G9]
Keyboard tracking will apply to the range below the speci-
fied note number.
High (KBDTrk Key High) [C–1…G9]
Keyboard tracking will apply to the range above the speci-
fied note number.
Ramp (Ramp Setting):
Specifies the angle of keyboard tracking.
Low (KBDTrk Ramp Low) [–99…+99]
High (KBDTrk Ramp High) [–99…+99]
If “Int. to A (KBDTrk Int. to A)” and “Int. to B (KBDTrk Int.
to B)” are set to +50, “Low (KBDTrk Ramp Low)” is set to
–62 and “High (KBDTrk Ramp High)” is set to +62, the angle
of the change in cutoff frequency will correspond to the key
location (pitch). This means that the oscillation that occurs
when you increase the “Resonance (A Resonance)” (4.1–1b)
will correspond to the keyboard location.
If you set “Low (KBDTrk Ramp Low)” to +43 and “High
(KBDTrk Ramp High)” to –43, the cutoff frequency will not
be affected by keyboard location. Use this setting when you
do not want the cutoff frequency to change for each note.
How cutoff frequency is affected by keyboard location and the Ramp
setting
(“Int. to A,” “Int. to B”=+50)
Int. to A (KBDTrk Int. to A) [–99...+99]
Specifies the depth and direction of the effect on filter 1A
produced by keyboard tracking settings “Low (KBDTrk Key
Low),” “High (KBDTrk Key High),” “Low (KBDTrk Ramp
Low),” and “High (KBDTrk Ramp High).”
With positive (+) settings, the effect will be in the same
direction as the keyboard tracking settings.
With negative (–) settings, the effect will be in the opposite
direction.
