• Value Snap pop-up menu and field: Quantize sequencer step values, limiting them to
exact fractions of the available range. For example, a setting of 1/2 aligns bars to the
values 0%, 50%, and 100% when dragged vertically. Off disables quantization, which
lets you set step values freely. You can also step through available values with the
Previous and Next buttons (the arrows).
Note: Value Snap doesn’t move existing step values into alignment with quantized
positions; it only affects the response of step values when you move or create them in
the step editor.
• Edit Mode pop-up menu: Choose one of three edit modes. Your choice affects the
appearance and behavior of the step editor to the right.
• Value: View and edit the value of each step in the pattern.
• Length: View and edit the length of each step in the pattern. Technically, you create
a pattern of longer and shorter envelope shapes so that the attack, sustain (gate),
and release stages fill a larger or smaller portion of the fixed step duration. These
lengths are combined with the overall sequencer Attack/Gate/Release settings to
determine the envelope shape of each step.
• Swing: Create variations in the timing of steps. Each swing value ranges from 0 to
2; the middle value of 1 represents standard timing, while smaller values play earlier
and larger values play later. These swing values are combined with the overall
sequencer timing pattern set with the Swing knob.
• File button: Open a pop-up menu with sequencer-related commands.
• Preset submenu: Choose a preset sequencer configuration. This can be used as is,
or as a starting point for your own sequences.
• Save: Store the current sequencer configuration (step values, lengths, and swing
settings plus the sequencer control settings) in a new disk file (*.seq). The new
sequence name appears at the bottom of the Preset submenu.
• Copy/Paste: Store the current sequencer configuration in the Clipboard. Paste
applies the configuration currently found on the Clipboard.
• Clear: Reset the sequencer controls and pattern to default settings.
• Randomize: Apply random offsets to the Swing, Attack, Gate, and Release parameter
values.
• Import: See the Import data from a MIDI file task in this section.
• Swing knob: Adjust timing to create swing effects. Values over 0% increase the duration
of odd-numbered steps (1, 3, 5, and so on) while decreasing even-numbered step
lengths.
• Attack knob: Set the time required for each step to reach its peak level.
• Hold knob: Set the amount of time each step is held at its peak level.
• Release knob: Set the time required for each step to fall from its peak level to zero.
• Step editor: Shows steps numbered from left to right across the top of the display.
Steps are represented by vertical bars that you can edit directly. The appearance and
behavior of the step editor is determined by the active Edit Mode menu choice.
• Scroll bar: Drag the middle of the scroll bar to view steps that are not visible in the
display area.
