Editing Workflow

Sigil editing happens mainly in the Song Overview, Piano Roll, and Velocity Lane. The overview controls arrangement; the piano roll controls notes; the velocity lane controls dynamics.

---

Selecting a pattern

The piano roll always shows the pattern from the selected Song Overview cell.

• Click a filled cell to edit its notes.
• Click an empty cell to create or edit a blank pattern.
• Reused patterns are shared across multiple cells until you make a unique copy.

---

Drawing and erasing notes

• Left-click an empty piano roll position to create a note.
• Drag right while creating a note to set its duration.
• Drag an existing note to move it.
• Drag the right edge of a note to resize it.
• Right-click a note to erase it.
• Right-click and drag across notes to erase multiple notes.

Notes snap to the current grid resolution.

Auditioning notes

Click and hold a note to hear it through the active soundfont without starting transport playback. Release the mouse to stop preview.

This is useful for checking pitch and register while editing.

---

Selection and marquee mode

Use the Marquee button or shortcut to switch from draw mode to selection mode.

• Drag a box to select notes.
• Use Ctrl+A to select all notes in the current pattern.
• Hold Shift and click notes to add or remove them from the selection.
• Right-click in marquee mode for copy, paste, and delete actions.

When notes are selected, quick edit controls appear in the transport bar for pitch, velocity, and duration changes.

---

Scale highlighting

When key and scale are set, the piano roll highlights in-scale notes.

If Highlight out-of-scale notes is enabled, notes outside the scale are visually distinct. If Snap note entry to scale is enabled, new notes are forced to the nearest in-scale pitch.

---

Velocity lane

The velocity lane appears below the piano roll and shows one vertical bar per note.

• Taller bars mean higher velocity.
• Shorter bars mean softer notes.
• Click or drag a bar to change note velocity.

Use velocity variation to make patterns feel less robotic.

Song Overview

The Song Overview is the arrangement map.

• Rows are tracks.
• Columns are bars.
• Filled cells contain notes.
• Empty cells are silent for that track and bar.
• Shared pattern cells show reused musical material.

Right-clicking a cell opens pattern management and pattern tool actions.

Pattern reuse

Action	Purpose
Copy bar	Copies the current cell pattern.
Paste bar	Applies copied content to another cell.
Duplicate bar to next bar	Copies the current cell to the next bar.
Make unique copy	Breaks a reused pattern into an independent copy.
Reuse previous pattern	Links the cell to the pattern on its left.
Assign existing pattern	Lets you pick from existing project patterns.
Clear cell	Removes notes from the cell pattern.

Pattern tools

Pattern Tools apply musical operations to a whole cell pattern. Use Undo if a tool result is not what you wanted.

Transform tools

• Simplify reduces note density.
• Densify adds more notes.
• Octave Up Variant and Octave Down Variant shift the pattern by an octave.
• Rhythm Shift Left and Rhythm Shift Right move timing earlier or later.
• Apply Groove bakes the project groove into actual note timing.
• Humanize Timing, Humanize Velocity, and Humanize Length add performance variation.

Musical tools

• Syncopate adds off-beat rhythmic emphasis.
• Fit Pattern To Scale moves notes into the active scale.
• Clamp To Instrument Range keeps notes within a playable range.
• Scale Step Up and Scale Step Down transpose by scale degree.

Harmony tools

• Fit Pattern To Chord aligns notes with the assigned bar chord.
• Add Chord Tones adds supporting harmony.
• Bass Follow Chord Root aligns bass notes with chord roots.
• Arpeggiate spreads chord tones over time.
• Strum Chord offsets chord notes slightly.
• Invert Up and Invert Down rotate chord voicings.
• Open Voicing spreads notes apart.
• Close Voicing compresses notes into a tighter voicing.

Drum and expression tools

• Add Hi-Hats adds a simple hi-hat pulse.
• Add End Fill writes a short transition fill.
• Simplify Kick / Snare removes redundant drum hits.
• Tighten Groove snaps drum timing toward the grid.
• Accent Downbeats increases beat-one emphasis.
• Soften Offbeats reduces offbeat velocity.
• Staccato shortens notes.
• Legato lengthens notes.
