Skyline & Piano Roll

Skyline merges two essential production environments: the linear song arranger (Song Mode) and the detailed Piano Roll note editor.

1. Song Mode Arranger

Song Mode organizes patterns and sequences into a complete, structured musical composition:

• Track Lanes: Each horizontal lane corresponds to an active instrument track.
• Bar Ruler: Measures are numbered linearly across the top timeline ruler.
• Pattern Placement: Double-clicking an empty timeline cell places the currently selected pattern from the library.
• Vertical Reordering: Pattern clips can be dragged freely between track lanes without software collisions.
• Clip Deletion: Select any pattern clip and press Delete or Backspace to remove it.

2. Piano Roll Note Editor

The Piano Roll allows note-by-note musical composition and editing for synthesizer tracks:

Key Range & Octaves

The vertical keyboard spans octaves C1 (sub-bass) through C7 (lead highs). Each horizontal row represents a semitone step.

Note Creation and Editing

• Draw Note: Click inside any temporal cell on the grid.
• Resize Note: Drag the right edge of a note to adjust its length (sixteenth note, eighth note, quarter note). The application memorizes your last resized duration for subsequent note placements during that session.
• Delete Note: Click on an existing note block to remove it.
• Velocity: Visualized by opacity or bar indicators along the lower note edge.

3. Scale Snapping & Harmonic Locking

The Piano Roll enforces musical coherence based on the global project key:

• Notes belonging to the selected scale are highlighted across the grid.
• Out-of-scale semitones are visually dimmed or disabled to prevent dissonant entries.
• All tracks maintain strict harmonic alignment with the chosen musical mode.
