Gate Control:
Source [List of AMS Sources]
This selects the AMS source to control the gate.
Control At Note-On Only [Off, On]
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 [–99...+99]
This sets the value of the Control Source at which 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 under At & Above Threshold.
Below Threshold [Fixed Value, AMS A]
This selects whether Below Threshold uses a preset value,
or the selected AMS source.
Fixed Value [–99...+99]
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 [List of AMS Sources]
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)
[Fixed Value, AMS B]
This selects whether At & Above Threshold uses a preset
value, or the selected AMS source.
Fixed Value [–99...+99]
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 [List of AMS Sources]
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
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: Ribbon: CC#16.
6. On the OSC Pitch page, assign the AMS Mixer to con-
trol the pitch.
7. Also on OSC Pitch, set the standard Ribbon amount to
0.
This way, only the AMS Mixer’s processed version of the
Ribbon will affect the pitch.
8. With the foot-switch off, play a chord, and hold it
through step 9.
9. Press down on and hold the footswitch, and then play a
new note above the chord.
10. Use the ribbon to bend the pitch of the new note.
The new note will bend, but the original chord (played
before you pressed on the foot-switch) will not.
Selective pitch-bend, using only the joystick
You can also use a single AMS source as both the Control
Source and a value source:
1. Set the Control Source to JS X.
2. Set Control At Note-On Only to On (checked).
3. Set the Threshold to 00.
4. Set Below Threshold to AMS A: JS X.
5. Set At & Above Threshold to a Fixed Value of 00.
6. On the OSC Pitch page, assign the AMS Mixer to con-
trol the pitch.
7. Also on OSC Pitch, set the standard JS+X and JS–X
amounts to 0.
This way, only the AMS Mixer’s processed version of the
joystick will affect the pitch.
8. With the joystick in the center, play a chord, and hold it
through step 9.
9. Bend the joystick to the left, and then play a new note
above the chord.
10. Use the joystick to bend the pitch of the new note.
The new note will bend, but the original chord (played
before you bent the joystick down) will not. This method is
particularly good for bending the top note of a chord up to
pitch.
Generating a static value
Sometimes, it can be handy to have a preset value as an
AMS source. The Gate is one way to create this. To do so:
1. Set both Below Threshold and At & Above Threshold
to Fixed Value, and enter the same value into each.
Now, the AMS mixer will always generate this static value.

6–2: OSC1 AMS Mix2
This is the second AMS Mixer for Oscillator 1. The
parameters are exactly the same as those for AMS Mixer 1,
as described under “6–1a: AMS Mixer 1” on page 70.
