👋 Introducing NOPIS - Your Digital Music Composing Sidekick

Hi everyone!

I'm excited to share a project I've been working on that I think could be genuinely useful for music producers and audio engineers. I'd love to get your feedback!

🎵 What is NOPIS?

NOPIS (Numerical Observation-based Production Interface System) is a desktop and web application that indexes your unique music production and mixing style. It observes your parameter adjustments in real-time and provides observational, context-aware suggestions to help maintain consistency across projects.

The key difference? It's not AI. NOPIS uses transparent statistical pattern recognition (EWMA) instead of black-box machine learning - so you always understand why it's making suggestions.

✨ Key Features

• Real-time DAW Integration: Bidirectional OSC communication for live parameter observation and suggestion delivery
• Context-Aware observational index : Tracks patterns across different contexts (mixing, recording, mastering, editing) and track types (drums, bass, vocals, guitar, synth, etc.)
• Pattern-Based Suggestions: Indexing your EQ preferences, compression ratios, reverb settings, and more - then suggests them when working on similar tracks
• Multi-Language Support: Full interface translation in English, Spanish, and French
• Professional Themes: Multiple dark-optimized themes (Night, Ocean, Forest, Cyber, Studio, etc.) for different studio lighting conditions
• Privacy-First: All Analyzed data stored locally on your machine - no cloud required, no data collection

💡 Real-World Example

Imagine you're mixing bass tracks and you consistently boost 80Hz by +3dB and apply 4:1 compression. NOPIS observes this pattern across multiple sessions. Next time you load a bass track, it suggests: "Based on 15 similar adjustments, try EQ Low +3.2dB and Compression 4.1:1 (92% confidence)"

🛠️ Tech Stack

• Frontend: React + TypeScript with Tailwind CSS
• Backend: Express.js + WebSocket for real-time communication
• Desktop: Electron (cross-platform: Windows, macOS, Linux)
• DAW Communication: OSC (Open Sound Control) protocol on port 9000
• Payment & Licensing: Gumroad integration for license validation
• Codebase License: MIT (open source) with commercial desktop distribution

💰 Licensing Model

NOPIS uses a unique hybrid approach:

• Open Source Codebase: The React/Node.js code is MIT licensed and freely available on GitHub
• Commercial Desktop App: Pay-once model ($50) for the packaged desktop version with 50 lifetime licenses available
• License Activation: Secure Gumroad license key validation with support for up to 3 devices per license

This model supports continued development while keeping the code open for learning, contributions, and community improvements.

🌟 Why This Approach?

Rather than training neural networks, NOPIS uses exponentially weighted moving averages (EWMA) to learn patterns. This means:

• Transparent, deterministic behavior - no black box
• Lightweight and fast - no GPU required
• You can trust and understand every suggestion
• Perfect for professional audio work where consistency matters

🤝 Looking for Feedback

If you have experience with:

• DAWs and music production workflows
• React/Node.js/Electron applications
• OSC protocol or real-time audio tools
• Open-source project maintenance and community building

I am New to all this! I would really appreciate your thoughts, suggestions, or advice! Whether it's about the technical implementation, UX/UI, or navigating the open-source community - all constructive feedback is welcome.

🚀 Want to Contribute?

NOPIS is MIT licensed and open for contributions. Whether you're interested in adding new DAW integrations, improving the learning algorithms, or adding more language translations - I'd love to collaborate!

Thanks for checking it out! 🎶
