Assemblage is a freeform score editor (and sequencer) inspired by John Cage's Bracket Notation system. Cage used brackets to indicate flexible time windows where events could occur, embracing chance and indeterminacy in composition.

Cage's Bracket Concept: In Cage's graphic scores, brackets represent time brackets—flexible containers where musical events can float freely within specified time ranges. This allows performers interpretive freedom while maintaining structural boundaries.

How to Use:

1. Drag & Drop
Drag symbols from left panel to timeline

2. Adjust Duration
Drag bracket corners to change length

3. Move Brackets
Drag anywhere on bracket to move it

4. Multi-Select
Ctrl+Click or Shift+Click multiple brackets

5. Copy/Paste
Ctrl+C / Ctrl+V with brackets selected

6. MIDI Notes
Select bracket, press N, choose notes/channel

7. Per-Bracket MIDI
Each bracket has its own volume, pan, channel

8. MIDI Panel (M)
Toggle MIDI controls with M key

9. Audio Samples
Right-click symbols to load audio files

10. Export Audio
Export entire composition as WAV file

11. Generate Scores
Create random scores using algorithms

12. MIDI Scale Generation
Generate brackets with notes from scales

13. MIDI Randomization
Randomize channels, volumes, panning

14. Reverb & Effects
Add reverb to audio playback

15. Undo/Redo
Ctrl+Z / Ctrl+Shift+Z or Ctrl+Y

MIDI Features:

Per-Bracket MIDI Controls:

Randomize Volumes (custom range)
Randomize Pan (different panning modes)
Notes per Bracket (1-4 notes)
PER COLOR MIDI Channel when Random Color is On

Symbol Categories:

Descriptions are based on personal conceptual assosiations.
Adjust to your imagination.

Low: Deep frequency textures

Noise: Surface noise & granular textures

Pitch: Pitch contours & melodic topographies

Temporal: Rhythmic structures & patterns

Sustain: Continuous sounds & evolving textures

Texture: Physical & surface characteristics

Process: Conceptual & procedural ideas

Custom: Create your own symbols

DMT:

Switch between deterministic & random playback modes.

Checked: Samples start at the beginning of a bracket

Checked: If more than 1 repeatition, playback is divided equally within the time length of a bracket

Unchecked: Samples play randomly within the time period of a bracket

Generation Methods:

Markov Chain: Probabilistic transitions

Lorenz Attractor: Chaotic system patterns

Rossler Attractor: Simpler chaotic system

Cellular Automata: Based on Rule 110

MIDI Notes: Scale-based note generation

Density Control: Adjust bracket density (10-100%)

Random Colors: Choose color palette size

Spins & Intensity: Include random rotation

Hint > Color Intensity: Connected to Sample Volume & MIDI Velocity
