Editing Figure

Selection

Segment Selection: Click on a symbol to select the segment it belongs to.

Click on the selection again to switch to the Symbol Selection tool.
Move or transpose the selection with the Arrow Keys or by dragging it to a new place.
Drag a selection to move it. Hold down ⌥ Ctrl to make a copy.
Drag at the top, bottom or right end to stretch the segment.
Drag the right end while holding ⌥ Alt to alter the length of all symbols.
Hold down ⌘ Control and drag up or down to alter the velocity of all symbols proportionally by a percentage.
Hold down ⌘ Control to unlock the grid while you are resizing or moving an object.
Ungroup a segment with ⌘U Control-U.

Symbol Selection: Click on a symbol to select it.

Click on the selection again to switch to the Segment Selection tool.
Drag a selection to move it. Hold down ⌥ Ctrl to make a copy.
Move or transpose the selected symbols with the Arrow Keys or by dragging it to a new place.
Drag the right end to alter the length of the selected symbols.
Hold down ⌘ Control and drag up or down to alter the velocity of selected symbols absolutely.
Hold down ⌘ Control to unlock the grid while you are resizing or moving an object.
Make a symbol become the anchor of its segment with ⌘R Control-R.

Multiple Selections

To select multiple symbols or segments, hold down ⌘ Control while you click on them, or drag a lasso rectangle around them.

Select all segments in the Figure with ⌘A Control-A.

Group multiple symbols or segments to form a new segment with ⌘G Control-G.

Span Selections

Keep in mind you can use the Span tool with Figure too. Use it to scroll the positions of segments around or transpose an entire Figure with the Arrow Keys.

Drawing

Use the Line and Freehand tools to draw new symbols and segments.

Click on a target position to insert a single Symbol.
Draw a line or curve to insert new symbols at positions that match the current Grid. The Anchor of a new segment is placed where you start the stroke. Thus, stroking backwards will put the anchor at the right end.
Draw a vertical line to insert a Chord.
Draw a horizontal line to create a single Symbol with a particular length. Enable Duplicates if you want multiple equal symbols be inserted along the current Grid.
Draw a diagonal line to insert symbols where it crosses the current Grid. Enable Duplicates if you are fine with symbols being repeated.
To append additional symbols to a segment, hold down ⇧Shift in the proximity of that segment and start drawing.
Try the Scale Board to assist you with drawing segments incrementally.

Rhythm

You will notice that drawing a random line or freehand curve on the Figure parameter looks instantly pretty but doesn't always work musically. The reason is rhythm. This is what you can do to ensure consistent rhythm.

Be sure to select a Grid that makes sense for the kind of phrase you have in mind. You can drop another phrase on the Grid Outlet to exactly recreate its rhythm.
Start and end the line or curve at rhythmically significant positions. Consider their weight (heavy or light).
Look at other phrases that work and resemble their structure.

Dynamics

Apart from very basic lines and sparsely placed notes, a Figure without expressive Velocity is bland. This is what you can do to add dynamics.

Open the Click Board and use it to emphasize heavy or light parts of the beat.
Recall a template from the right-click menu over the Velocity outlet.
Switch to Hyper Edit mode and use the Shape tool to sketch dynamics.
Select a segment and hold ⌘ Control while you move the mouse up or down to change dynamics proportionally. Hold down ⇧Shift in addition if you want to change values absolutely.
Select Velocity, click into the Parameter View and use the arrow keys to transpose values up or down.
Transfer dynamics of another phrase by dropping Velocity or Figure of that phrase on the Velocity outlet of the target phrase.

Tip: To save the clutter of an extra Velocity parameter, you can edit dynamics of a phrase in Hyper Edit mode. Alternatively, edit a physical Velocity and permanently apply it to the figure with Parameter > Save To Figure when done.

Hyper Edit

After switching to this mode with the tool H, you can edit the Velocity, Step and Length of a Figure as if they were physically present parameters. In reality however, your changes are immediately saved to the figure.

Note: Hyper Edit mode makes sense only where a Figure is present. If necessary, make a Snapshot beforehand.

Transform Menu

The menu Transform offers additional commands for the Figure parameter.

Reverse at Anchor: Flip segments horizontally at their anchor positions. In contrast to other reverse commands, this creates a wildly different figure.
Reverse at Onsets: Play segments backwards without altering symbol lengths. In contrast to the default "tape reverse", this turns a legato melody into partially overlapping notes.
Flip at Anchor: Mirror segments vertically at their anchor position.
Force Legato: Alter the lengths of symbols such that overlaps are removed and all gaps between them are closed.
Shorten Overlaps: Shorten symbols only where they overlap in time.
Remove Clashes: Shorten symbols only where two repeated symbols overlap.
Simulate Strumming: Turn a vertical chord into a strummed performance.
Simulate Pedal: Stretch all symbols to play until the end of the last symbol in a segment.
Simulate Broken Chord: Turn a vertical chord into a broken, arpeggio-once performance.
Select: Select all segments of the current type.
Focus On: Highlight segments of the current type and dim all others.
Change: Convert all selected segments to the current symbol type.
Simplify Chords: Reduces chord segments to fewer symbols and adjusts segment properties to render the chord as it is configured with the Harmony parameter.
Round Accidentals: Round all symbols to diatonic steps.
Remove Symbol Tags: Drop all tags from a take (Take only).
