BYODD Reactive Fork

BYOD (Build Your Own Distortion) is Chowdhury DSP's open-source guitar plugin: a node graph of distortion circuits, filters and utilities that you wire into your own effect.

BYODD adds the second D, dynamics. Any knob on any module can now follow a signal, so the effect reacts to how you play instead of sitting at one setting.

The simplest version: Input → Dynamics Tracker → Distortion → Output, with the tracker's envelope patched into the distortion's Drive knob. Pick harder, get more drive.

What it adds

• Knob Mod ports. Every module with a continuous parameter gets one extra input. Patch a signal into it and all of that module's knobs follow it on top of their own positions, greyed out while they're driven. Each knob has its own depth, from −100% to +100%, so knobs can move independently and in opposite directions.
• Dynamics Tracker. An envelope follower with the dry audio passed straight through, so it drops in anywhere in the chain. Sense, Attack and Release shape it, and a bipolar Amount knob scales or inverts it.
• Mod Shaper. Sits between a modulation source and a Knob Mod port: Scale (negative inverts), Offset, Min/Max clamping and Smooth. Chain several for more complex curves.

BYOD's existing Level Detective, Param Modulator and MIDI Modulator also work as sources.
