Program mode
Gate Control uses a third AMS source to switch between two
AMS inputs (or a fixed value). For more information, please see
the "Gate Control" section on page 49.

Amt B
A+B merges two AMS sources into one. This can be handy when
you need to add one more modulation source to a parameter, but
you've already used up all of the available AMS slots.
For instance, let's say that you're using an LFO to modulate Filter
Resonance, and then you decide that it would be interesting to
scale that parameter with an EG as well. Resonance has only a
single AMS input, but you can easily merge the LFO and the EG
together using the A+B AMS Mixer:
1. Assign the LFO to AMS A.
2. Assign the EG to AMS B.
3. Assign the AMS Mixer as the Filter Resonance AMS
source.
AMS Mixer A+B example
AMS A: LFO
AMS B: EG
A+B Output
AMS A
This selects the first AMS input.
For a list of AMS sources, please see "AMS (Alternate
Modulation Source) List" on page 292.
AMS A Amount
This controls the depth and direction of the AMS A input.
AMS B
This selects the second AMS input.
For a list of AMS sources, please see "AMS (Alternate
Modulation Source) List" on page 292.
AMS B Amount
This controls the depth and direction of the AMS B input.

Amt AxB
AMS Mixer, Type =Amt A x B
This Mixer Type uses AMS B to scale the amount of AMS A. For
instance, you can control the amount of LFO1 with the Filter EG,
or control the amount of the Pitch EG with the modulation wheel.
Output
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 292.
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 292.

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
[–99...+99]
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 the AMS A
[–99...+99]
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.
