# REQUIREMENTS DOCUMENT: ABLETON LIVE 11 REPLICA APPLICATION ## 1. EXECUTIVE SUMMARY This document outlines the requirements for developing a replica application of Ableton Live 11 Standard, a professional digital audio workstation (DAW). The requirements focus on replicating the user interface, core functionality, and workflow capabilities of the original software based on the provided visual description. ## 2. STAKEHOLDERS - Music producers and composers - Audio engineers - Music educators and students - Application developers - UI/UX designers - QA testers ## 3. BUSINESS REQUIREMENTS BR-1: Create a functional replica of Ableton Live 11 Standard's interface and core capabilities BR-2: Support digital music production workflows for various user experience levels BR-3: Maintain the efficiency and usability of the original software design BR-4: Deliver a solution that accurately replicates the visual design and interaction patterns ## 4. FUNCTIONAL REQUIREMENTS ### User Interface Components FR-1: Implement a window title bar displaying project name and application title FR-2: Develop a standard menu bar with File, Edit, Create, View, Options, and Help options FR-3: Create a transport section including tempo control (default 120.00 BPM), time signature settings (default 4/4), and playback controls FR-4: Implement position indicators showing measure numbers (format: 1.1.1) FR-5: Develop a track grid system with clip slots organized in rows and columns ### Track Management FR-6: Support creation and management of MIDI tracks with purple-pink headers FR-7: Support creation and management of Audio tracks with blue headers FR-8: Implement return effect tracks (at minimum "A Reverb" and "B Delay") with orange-pink headers FR-9: Include Master track with blue header and master output controls FR-10: Provide monitoring settings and I/O routing options for all tracks FR-11: Implement level meters for visual feedback of audio levels on all tracks FR-12: Create vertical volume faders with decibel markings from -inf to 0 dB FR-13: Include pan controls for spatial positioning of audio ### Session View Functionality FR-14: Implement drag-and-drop functionality with "Drop Files and Devices Here" area in the central grid FR-15: Create "Mixer Drop Area" with instructional text for creating new tracks FR-16: Provide "Drop an Instrument or Sample Here" zone for quickly adding sound sources FR-17: Support clip launching and playback from the session grid FR-18: Enable send controls for routing audio to return tracks ### Content Creation FR-19: Allow recording of MIDI and audio input FR-20: Support importing and placement of audio files into tracks FR-21: Provide functionality to create and edit MIDI patterns ## 5. NON-FUNCTIONAL REQUIREMENTS ### Visual Design NFR-1: Implement the predominantly gray color scheme as seen in the original interface NFR-2: Apply correct color-coding for track types (MIDI: purple-pink, Audio: blue, Return: orange-pink) NFR-3: Use yellow-amber color for track numbers NFR-4: Style transport controls in dark gray with red, green, and yellow accent elements NFR-5: Maintain visual proportions and spatial relationships between interface elements ### Performance NFR-6: Ensure responsive interface with minimal latency for real-time music production NFR-7: Optimize audio processing to prevent dropouts or glitches during playback and recording NFR-8: Support smooth scrolling and navigation within the application interface ### Usability NFR-9: Maintain intuitive drag-and-drop interactions for file and device placement NFR-10: Provide clear visual feedback for all user interactions NFR-11: Implement consistent keyboard shortcuts matching industry standards ## 6. CONSTRAINTS AND ASSUMPTIONS ### Constraints C-1: Development must accurately replicate the visual appearance of Ableton Live 11 Standard C-2: The application must maintain the core layout and workflow of the original software C-3: Legal considerations regarding intellectual property must be addressed before commercial release ### Assumptions A-1: Users have basic knowledge of digital audio workstations A-2: The replica will focus on core functionality rather than advanced features A-3: Standard audio and MIDI I/O capabilities are available on target systems ## 7. DEPENDENCIES D-1: Audio processing libraries for audio manipulation and playback D-2: MIDI processing capabilities for handling MIDI data D-3: UI development framework capable of replicating the complex interface D-4: File system access for saving and loading projects and media files ## 8. PRIORITIZATION ### Must Have - Core user interface components (FR-1 through FR-5) - Basic track management (FR-6 through FR-9) - Volume and pan controls (FR-12, FR-13) - Basic session view functionality (FR-14) - Core visual design elements (NFR-1 through NFR-5) ### Should Have - Complete track I/O options (FR-10, FR-11) - Extended session view functionality (FR-15 through FR-18) - Basic content creation tools (FR-19 through FR-21) - Performance optimizations (NFR-6 through NFR-8) ### Could Have - Advanced editing features - Additional track types - Extended device library - Customization options ### Won't Have (Initial Version) - Cloud collaboration features - Advanced sound design capabilities - Third-party plugin support - Hardware integration beyond basic MIDI controllers ## 9. OPEN QUESTIONS Q-1: What specific audio formats must be supported? Q-2: What are the minimum system requirements for acceptable performance? Q-3: Which specific features of the transport section need full implementation? Q-4: Are there any specific MIDI controllers that should be supported by default? Q-5: What level of audio processing capabilities is required (effects, routing complexity)? ## 10. GLOSSARY - DAW: Digital Audio Workstation, software used for recording, editing, and producing audio files - MIDI: Musical Instrument Digital Interface, a technical standard for connecting electronic musical instruments - Session View: Ableton's grid-based view for launching clips and arranging music non-linearly - Transport: Section of the interface containing playback controls, tempo, and time signature settings - I/O: Input/Output, referring to audio routing options - Return Tracks: Special tracks used for effects processing via sends from other tracks - Send Controls: Knobs that determine how much of a track's signal is sent to return tracks - Pan: Control that adjusts the left-right positioning of audio in the stereo field
