Modulating Program parameters per step
Each step has two AMS Output values. These act kind of
like step sequencers, allowing you to modulate any AMS
destination in the Program. In other words, virtually any
Program-level parameter can have a different setting for
each step of the Wave Sequence.
For instance, to adjust the Filter Frequency separately for
each step:
1. Select the Program that you'll use for the Wave
Sequence.
2. Go to the PROGRAM > Filter– Filter1 Mod. page.
This page has the filter modulation parameters for OSC1.
3. Under Filter A Modulation, set one of the AMS
sources to Wave Seq AMS Out1.
4. Set the Intensity as desired.
This means that the AMS 1 output will modulate the
Filter Frequency. Now, you just need to set up the Wave
Sequence to send values out:
5. Go to the GLOBAL > WaveSeq– Step Parameters
page.
6. For each step, enter the desired value for AMS Out1.

7. Go to the OSC1 Basic tab of the PROGRAM >
OSC/Pitch page.
8. Set MS1 to use the Wave Sequence you edited in step
6.
The Filter Frequency will now change with every step.
You may wonder - what if the Program uses more than
one Wave Sequence, and each is sending out different
AMS values? Not to worry. Under the hood, each Wave
Sequence actually has its own complete voice structure,
which allows the AMS values to be different for each
one.
Modulating individual steps with the AMS Mixer
You can combine the Wave Sequence AMS Outputs with the
AMS Mixer to modulate individual steps. For instance, you
can set up SW1 to mute a particular step. We'll start by
assuming that you have already set OSC1 to play the Wave
Sequence. Then:
1. On the GLOBAL > WaveSeq– Step Parameters page,
set step 1's AMS Out1 to 127.
2. Set AMS Out1 for all other steps to 0.
3. Go to the OSC1 AMS Mix tab of the PROGRAM >
AMS Mix/C.KeyTrk page.
4. On AMS Mixer 1, set the Type to Amt A x B.
5. For AMS A, select Wave Seq AMS Out 1.
6. Set the AMS A Amount to 00.
7. For AMS B, select SW 1 Mod (CC#80).
8. Set the AMS B Amount to +99.
9. Go to the Amp 1 Mod tab of the PROGRAM >
Amp/EQ page.
10.Under Amp Modulation, set the AMS source to AMS
Mixer 1.
11.Under the AMS source selection, set the Intensity to
–99.
SW1 will now mute and un-mute step 1. You can use this
same technique for any per-step modulation.
