Program P8: Step Seq/LFO
8–1: Step Sequencer
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. (For more information, see
“Creating melodic patterns with the Step Sequencer”
on page 165.)
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
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 “AMS (Alternate
Modulation Source) List” on page 967.
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).
Smoothing [0…99]
This control smooths the Step Sequencer’s output
signal, creating more gentle transitions between
values. Higher values mean more smoothing.
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.
