8–1: Step Sequencer
Overview
The Step Sequencer creates complex, rhythmic patterns, for
use as an AMS modulation source. For instance, you can
modulate a filter to create sample-and-hold effects, modulate
pitch to create melodic patterns, or modulate amplitude to
create pulsing, triggered-gate effects.
Each voice of the AL-1 has its own Step Sequencer, in
addition to the Common Step Sequencer shared by both EXi
instruments. To make all of the per-voice Step Sequencers
run in sync, set Key Sync to Off.
The sequence can have up to 32 steps, each with its own
level and duration. It can loop, or play only once. You can
also:
• Re-start the Step Sequencer via AMS
• Modulate the Start Step via AMS
• Use individual steps to either gate or do sample-and-hold
on a continuous AMS source, such as an EG or LFO
• Assign individual steps to create a random level
• Use Smoothing to create gentle, curving shapes
Step Sequencer usage tips

8–1a: Step Sequencer
Mode [Loop, One Shot]
Loop makes the Step Sequence loop continuously between
the Start Step and the End Step.
One Shot makes the Step Sequence play once from the Start
Step to the End Step, and then hold at the End Step. You
can still reset the Step Sequencer from AMS to make it play
again.
Start Step [1…32]
This is the step on which the sequence will start. If Mode is
set to Loop, this also sets the start of the loop.
AMS [List of AMS Sources]
This selects an AMS source to modulate the Start Step. For
a list of AMS sources, see “Alternate Modulation Source
(AMS) List” on page 901.
Intensity [-32…+32]
This controls the depth and direction of the Start Step
modulation.
End Step [01…32]
This sets the last step in the sequence. Once the sequence
reaches the End Step, it will either hold there until the note
goes away (if Mode is set to One Shot), or loop back to the
Start Step (if Mode is set to Loop).
Key Sync [Off, On]
When Key Sync is On, each note’s Step Sequencer is
independent, and the sequence always starts from the Start
Step at note-on.
