Modulation Source) List" on page 292.
Number Of Steps
This controls the severity of the effect. The lower the number of
steps, the more "steppy" the output will be.
For instance, when this is set to 2, there will be "steps" at 0, 50,
and 99. With a bipolar AMS input, there will also be steps at –50
and –99.
As another example, when it is set to 5, there will be steps at 0, 20,
40, 60, 80, and 99 (as well as –20, –40, –60, –80, and –99 for
bipolar inputs).
Tip: Quantized pitch bend wheel Pitch Bend
You can use the pitch bend wheel to create quantized pitch bends
that simulate sliding across the frets of a guitar, or jump-bend
sounds caused by differences in the length of the tube of a trumpet.
To do so:
1. Select the AMS Mixer as the Oscillator Pitch AMS input.
2. Set the Pitch AMS Intensity to any exact half-step value,
such as +5.00, +7.00, etc.
3. Set the Bend(+X), Bend(–X) amount to 0.00.
4. In the AMS Mixer, select the Pitch Bend as AMS A.
5. Set the Number Of Steps to the same number you used in
Step 2.
Now, playing the pitch bend wheel will create quantized pitch
bends.
Gate Control

Fixed Value

AMS
This Mixer Type lets you set up two different AMS sources (or
fixed AMS amounts), and then switch between the two using a
third AMS source.
It's similar to an audio gate with a side-chain, but with even more
flexibility since you get to choose what happens when the gate is
closed (below the threshold), as well as when it's open (above the
threshold).
You can also choose whether the gate will be able to open and
close continuously in response to the control source, or whether it
only opens or closes at the beginning of the note, and then stays
that way over the note's entire duration.
You can use the Gate to:
• Use a foot-switch (or other controller) to apply pitch-bend or
other effects to some notes, but not to others
• The parameter will be applied when the controller reaches a
specific threshold. For example, the velocity value could
control the filter resonance only if the velocity value exceeds
90.
• Use the modulation wheel, switches, or controllers to change
between two separate LFOs (or other AMS sources).
Gate Contro Source
This selects the AMS source to control the gate.

12: P–AMS MIXER 12–1: 1 (AMS Mixer1)
Control At Note-On Only
When this is enabled (checked), the value of the Control Source
at note-on will select the output (Below Threshold or At & Above
Threshold). The selected output will then remain active
throughout the duration of the note, regardless of any subsequent
change in the Control Source's value.
Note that the output value itself can continue to change; only the
selection of Below or At & Above is fixed.
Threshold
This sets the value of the Control Source where the gate opens or
closes.
Gate Output
If the value of the Control Source is less than the Threshold, the
Gate outputs the preset value or AMS source selected under Below
Threshold.
If the value of the Control Source is greater than or equal to the
Threshold, the Gate outputs the preset value or AMS source
selected in the At & Above Threshold parameter.
Below Threshold
This selects whether Below Threshold uses a preset value, or the
selected AMS source.
Fixed Value
This lets you set a specific value to be used when the Control
Source is less than the Threshold. This only applies when Below
Threshold is set to Fixed Value.
AMS A
This lets you set an AMS source to pass through the Gate when the
Control Source is less than the Threshold. This only applies
when Below Threshold is set to AMS A.
At & Above Thresh (At & Above Threshold)
This selects whether At & Above Threshold uses a preset value,
or the selected AMS source.
Fixed Value
This lets you set a specific value to be used when the Control
Source is greater than or equal to the Threshold. This only applies
when At & Above Threshold is set to Fixed Value.
AMS B
This lets you set an AMS source to pass through the Gate when the
Control Source is greater than or equal to the Threshold. This
only applies when At & Above Threshold is set to AMS B.
Tips on using the Gate
Selective pitch-bend, using a switch
You can use Control At Note-On Only to apply an effect to some
notes, but not others, based on the state of an AMS source at the
start of the note. For instance:
1. Set the Control Source to Foot SW: CC#82
(Connect a foot switch, and set the G–INPUT/CTRL> FOOT page
Foot SW Assign parameter to Foot Switch (CC#82).)
2. Set Control At Note-On Only to On (checked).
3. Set the Threshold to 50.
4. Set Below Threshold to a Fixed Value of +00.
5. Set At & Above Threshold to AMS B: Pitch Bend
6. On the OSC Pitch page, assign the AMS Mixer to control
the pitch.
7. Turn off the foot switch, and while holding down a chord,
move the pitch bend wheel. The pitch will not change.
