Repeater Orchestra for Norns

Repeater Orchestra is a textural delay instrument that creates dense clouds of repeating audio. It consists of multiple tempo-synced delay lines (up to 50) with randomized timing, gain, and panning.

This project is a port of the original Repeater Orchestra web application by Bryant Smith.

• Original Concept & JavaScript Implementation: Bryant Smith
• Original Web Version: Repeater Orchestra on CodePen
• Original Software Demo: Video Demonstration by Sylvain Poitras
• Norns Port: Ported with assistance from Gemini CLI.

Norns Implementation

The Norns script adapts the original concept for hardware control and adds new functionality:

• Freeze: Instantly lock the current audio buffer into an infinite loop, allowing you to build a texture and play over it.
• Dry/Wet Mix: Blend between the direct input signal and the delay cloud (E1).
• Independent Monitoring: The dry signal is monitored independently of the delay “Gate”, allowing you to play over the loop even when not feeding new audio into the delays.
• Hardware Mapping: Intuitive control over gains, tempo, and freeze states.

Controls

• K1: Shift modifier
• K2: Toggle Gate (Mic On/Off) - When ON, audio feeds the delay lines.
• K3: Toggle Freeze - Locks the current delay buffers for infinite looping.

• Shift + K3: Clear all delays.

• E1: Dry/Wet Mix (0% = Dry only, 100% = Wet only)
• E2: Input Gain
• Shift + E2: Output (Master) Gain
• E3: Tempo (BPM)
• Shift + E3: Number of Active Delays (1-50)
