Explain
Sonic Pi provides a Ruby-based DSL for musical composition and live performance.
Users can program beats, synths, loops, and samples using code.
It encourages learning programming through music and creativity.
Supports real-time audio output with low latency.
Can be used for both educational and professional musical applications.
Core Features
`play` - plays a note or chord
`sample` - plays audio samples
`sleep` - defines duration between notes
`live_loop` - loops music in real-time
Threading and concurrency for layered compositions
Basic Concepts Overview
Note values (e.g., `:C4`, `:E3`) for pitch
Synths (e.g., `:beep`, `:prophet`) for sound types
`sleep` to define note duration
`live_loop` for repeating sections
Effects (FX) and samples to modify or layer sound
Project Structure
Single `.spi` script file per composition
Optional multiple buffers for organization
Assets folder for custom samples
No complex file system required
Entire composition often contained in one live code session
Building Workflow
Write code in Sonic Pi editor
Use `play` or `sample` commands to generate sound
Define loops with `live_loop` for repetition
Add FX and timing adjustments
Iterate and modify in real-time while listening
Difficulty Use Cases
Beginner: play simple notes and loops
Intermediate: combine loops and synths
Advanced: use FX, concurrency, and samples creatively
Expert: live coding performance and algorithmic composition
Architect: integrate Sonic Pi with sensors or external MIDI controllers
