I'll add a tape delay module that emulates the warm, slightly degraded sound of classic tape delay units. This will include controls for time, feedback, and tape characteristics. ```html iPad Synthesizer with Tape Delay

``` ### Key Additions for Tape Delay Module: 1. **Tape Delay Module UI**: - Added a new control module with an orange color scheme for the tape delay - Four main controls: - **Time**: Controls the delay time (10ms to 1000ms) - **Feedback**: Controls how many repeats (0% to 90%) - **Mix**: Balances dry and wet signals (0% to 100%) - Includes an On/Off switch for CPU optimization 2. **Tape Emulation Features**: - **Wow & Flutter**: Simulates tape speed variations using LFOs - **Saturation**: Subtle wave-shaper for tape saturation - **High-Pass Filter**: Reduces artificial high frequencies - **Degradation**: Emulates the warm, slightly degraded sound of tape 3. **Audio Processing**: - Uses DelayNode for the basic delay effect - Implements feedback loop for repeats - Adds modulation to delay time for tape wow/flutter - Includes saturation for warmth and character 4. **Signal Flow**: - The tape delay is placed after the phaser and before the gain stage - Signal flow: Oscillator → [Filter] → [Phaser] → [Tape Delay] → Gain → Outputs - Each note gets its own tape delay for proper polyphonic operation 5. **Real-time Updates**: - Added `updateDelay()` function to update all active delays when parameters change - Delay parameters can be adjusted in real-time while notes are playing ### Tape Delay Characteristics: 1. **Classic Echo**: - Time: 250-500ms - Feedback: 30-50% - Mix: 20-40% - Creates clean, rhythmic echoes 2. **Slapback Echo**: - Time: 100-250ms - Feedback: 40-60% - Mix: 30-50% - Shorter delay with more repeats 3. **Degrading Tape**: - Time: 500-800ms - Feedback: 50-70% - Mix: 40-60% - Longer delay with more character from saturation 4. **Ambient Wash**: - Time: 800-1000ms - Feedback: 60-80% - Mix: 50-70% - Creates atmospheric, swirling textures The tape delay adds a classic effect that can transform simple sounds into rich, evolving textures. The tape emulation adds warmth and character that's missing from digital delays, making it perfect for creating vintage-style echoes and atmospheric pads. Combined with the other effects, you can create incredibly complex and organic sounds.
