High pass lter
This type of filter allows the high frequency range to pass
and cuts the low frequency range. Use this when you wish
to make the sound thinner. However if the cutoff fre-
quency (Frequency) is raised excessively high, the volume
will become very low.
Resonance
When “Resonance” is set to a higher value, the overtones
in the region of the cutoff frequency will be boosted as
shown in the diagram below, giving a distinctive charac-
ter to the sound.
Filter1 Mod. page
Controllers and the filter EG can be used to modulate the
filter cutoff frequency that was specified in the Filter1
page. By using a controller to vary the tone or by using an
EG to create time-varying changes, you can add a rich
variety of tonal change to the sound.
Keyboard Track
This varies the cutoff frequency according to the position
of the key on the keyboard that you play.
When “Ramp Low” is set to a positive (+) value, the
cutoff frequency will rise as you play lower on the
keyboard, making the sound brighter. When set to a
negative (–) value, the cutoff frequency will fall as you
play lower on the keyboard, making the sound darker.
When “Ramp High” is set to a positive (+) value, the
cutoff frequency will rise as you play higher on the
keyboard, making the sound brighter. When set to a
negative (–) value, the cutoff frequency will fall as you
play higher on the keyboard, making the sound
darker.
•“Intensity to A” and “Intensity to B” adjust the effect
that keyboard tracking will have on filters A and B
(PG p.17).
Filter EG
Adjusts the effect produced by the filter EG, whose set-
tings are made in the EG page.
Use the “Velocity to A” and “Velocity to B” settings to
specify the effect of velocity on the filter EG.
Use the “Intensity to A” and “Intensity to B” settings
to specify the depth of the filter EG.
•“Into A (AMS Int. to A)” and “Into B (AMS Int. to A)”
adjust the effect that AMS will have on the filter EG
depth.
These three settings will determine the depth of the
tonal change produced by the filter EG.
Filter A/B Modulation
Set this when you wish to produce tonal change by using
controllers etc. to vary the cutoff frequency.
Filter1 LFO Mod. page
Indicates settings that allow the LFO to produce cyclic
changes in tone (a “wah” effect).
Intensity to A (LFO Int. to A)” and “Intensity to B (LFO
Int. to B)” specify by how much the LFO will change the
tone.
JS-Y Intensity to A” and “JS-Y Intensity to B” specify
the depth of the wah effect that will be produced by the
LFO when the joystick of TRITON STUDIO is moved
toward yourself, or when CC#2 is received.
Intensity to A (LFO1 AMS Int.to A)” and “Intensity to B
(LFO1 AMS Int. to B)” specify the depth of the wah effect
that will be produced by the LFO when “AMS (LFO1
AMS)” is used. For example if “AMS (LFO1 AMS)” is set
to After Touch, applying pressure to the keyboard of the
TRITON STUDIO, will produce a wah effect.
Filter1 EG page
Indicates settings for the filter EG, which controls time-
variant changes in tone. Make settings for the EG here,
and set the depth of its effect in the Filter1 Mod. page Fil-
ter EG parameter (PG p.19).
Filter EG and Amplier EG
When the Filter EG changes the cutoff frequency, the tone
will change. However depending on the volume changes
produced by the Amplifier EG, this can be heard in differ-
ent ways. For example by changing the speed at which the
tone and volume begin (attack) or decay, you can signifi-
cantly vary the character of the tonal change. It is a good
idea to adjust the changes of both the Filter EG (tone) and
the Amplifier EG (volume) as you proceed with editing.
(“Amp1 EG page)
Amplier settings P4: Edit-Amp
These settings affect the volume. Here you can adjust the
way in which the Amp EG and LFO produce time-varying
and cyclic changes in volume, and how the controllers etc.
will affect the volume.
Amp1 applies to OSC1, and Amp2 applies to OSC2.
Amp2 can be used if “Oscillator Mode” is set to Double.
