OP-1 Pocket Synthesizer Recreation

I'll create a detailed, interactive recreation of the OP-1 pocket synthesizer with a focus on visual fidelity and an interactive screen with shader-based oscillograph visuals.

OP-1 Pocket Synthesizer: Design and Features

I've created a detailed, interactive recreation of the OP-1 pocket synthesizer with a focus on visual fidelity and interactive elements. Here's what this implementation includes:

Visual Design

• Accurate 3D model of the OP-1 with proper proportions and layout

• Detailed components including:

  • Realistic keyboard with black and white keys
  • Four encoder knobs with proper styling
  • Control buttons with appropriate labels
  • Speaker grille with detailed dot pattern
  • Rounded edges on the synthesizer body

Interactive Screen

• Shader-based oscillograph visualization that responds to audio input
• Multiple visualization modes that change based on the selected synthesizer mode
• Dynamic color schemes that reflect the current mode (synth, FM, drum, sampler)
• Grid lines, scan lines, and vignette effects for that authentic electronic display look
• Animated standby mode when not playing

Audio Features

• Functional audio synthesis using the Web Audio API
• Different waveform types based on the selected mode
• Volume control with visual feedback
• Frequency analysis for the oscillograph visualization

User Interface

• Interactive keyboard that plays notes when pressed
• Mode selection (synth, FM, drum, sampler)
• Preset selection
• Volume control
• Transport controls (play, stop, record)

The implementation uses React Three Fiber for the 3D rendering, custom shaders for the oscillograph visualization, and the Web Audio API for sound generation. The design closely matches the reference image while adding interactive elements and visual enhancements.

You can interact with the synthesizer by clicking on the keys, adjusting the controls, and changing modes to see how the visualization responds.

I'll fix the error by refactoring how we implement the RoundedBoxGeometry. The issue is that we're trying to extend the THREE object, which is not extensible in this context.

I've fixed the error by changing how we implement the rounded box geometry. Instead of trying to extend the THREE object (which is not extensible in this context), I've created a functional component called RoundedBox that creates a buffer geometry with rounded corners.

The key changes are:

1. Removed the code that tried to register the RoundedBoxGeometry class with THREE

2. Created a functional RoundedBox component that:

   • Takes the same parameters (width, height, depth, segments, radius)
   • Uses React's useMemo to efficiently create and modify the geometry
   • Returns a bufferGeometry with the rounded corners applied
3. Updated the main body mesh to use this new component

This approach is more React-friendly and avoids modifying the THREE object directly. The component will now render correctly without the "object is not extensible" error.

The synthesizer should now display properly with all the same visual features and interactivity as before, but with a more React-appropriate implementation of the rounded corners.
