Modulation Source) List" on page 588.
AMS B Amount
This controls the depth and direction of the AMS B input.
Amt AxB
AMS Mixer, Type =Amt A x B
AMS A
AMS B
Amt B Amt A
This Mixer Type uses AMS B to scale the amount of AMS A.
For instance, you can control the amount LFO1 with the
Filter EG, or control the amount of the Pitch EG with the
ribbon.
AMS Mixer Amt AxB example
AMS A: LFO
AMS B: EG
Amt A*B Output
AMS A
This selects the first AMS source, which can then be scaled
by AMS B.
For a list of AMS sources, please see "AMS (Alternate
Modulation Source) List" on page 588.
AMS A Amount
This controls the initial amount of AMS A, before
modulation from AMS B. Input from AMS B then adds to
this initial amount.
Even if Amount A is set to 0, AMS B can still control the final
amount of AMS A over the full +/–99 range.
AMS B
This selects the second AMS source, to scale the amount of
AMS A.
For a list of AMS sources, please see "AMS (Alternate
Modulation Source) List" on page 588.
AMS B Amount
This controls the depth and direction of the AMS B
modulation of AMS A.
For example, if AMS A is set to LFO1 and AMS B is set to
the Filter EG, positive settings mean that the EG will
increase the amount of LFO1.
Tip: use SW 1/2 to turn an AMS source on and off
You can use Amt AxB to "gate" an AMS source:
1. Set AMS A to the desired source, and set AMS A
Amount to 0.

2. Set AMS B to SW1 or 2, and AMS B Amount to +99.
Now, SW1 or 2 will turn AMS A on and off.
Offset
AMS Mixer, Type = Offset
Amt A Offset A
AMS A
This simple processor adds a constant offset to the input,
and also allows you to double the gain of an AMS source.
For instance, you can use this to convert a bipolar LFO (both
negative and positive) to a unipolar LFO (positive only). To
do this:
1. Select the LFO as the AMS A input.
2. Set the AMS A Amount to 50.
This cuts the overall level of the LFO in half, so that instead
of swinging between –99 and +99, it only swings between
–50 and +50.
3. Set the AMS A Offset to 50.
This adds 50 to the LFO level, so that it now swings between
0 and +99, as shown below.

AMS A
This selects the AMS source to be offset.
For a list of AMS sources, please see "AMS (Alternate
Modulation Source) List" on page 588.
AMS A Amount
This controls the basic level of AMS A.
+199 doubles the original signal level, while –199 doubles
the level and inverts the phase. The values are clipped only
at the output; internally, they can be greater than the normal
range of –99 to +99.
