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.
In Alchemy in Logic Pro, the step editor shows steps numbered from left to right across the top of the display. The appearance and behavior of the step editor is determined by the active Edit Mode menu choice. In the default Value mode, for example, the value of each step is represented by a vertical bar. A blank column is shown when the value is zero.
