MDX-4

MDX-4 by Retromelon’s TOYZ – Modular FX Playground (VST3)

Modular-style routing meets powerful multi-effects control

MDX-4 is a one-of-a-kind VST3 multi-FX plugin that puts creative power in your hands. Developed by Retromelon’s TOYZ, this modular-style unit gives you complete freedom to route and combine effects in any order — just like a hardware modular synth, but fully digital and DAW-friendly.

Core Modules:

Distortion

Crush or saturate with the Limit and Shape controls for everything from vintage warmth to brutal grit.

Filter

Sculpt your sound with selectable Low Pass, High Pass, Band Pass, and Band Reject filter types.

Reverb

Choose from Gated, Freeze, or Normal reverb modes. Tweak Gate, Size, Width, Damp, and Mix to create lush textures or tight, rhythmic effects.

Delay

Switch between Stereo and Ping-Pong delay. Adjust timing, feedback, offset, and damping for rich, spatial soundscapes.

LFO Matrix (4 Total)

Modulate key parameters with 4 independent LFOs, each offering over 30 waveform types. Add motion, rhythm, and evolving textures.

Audio Routing

Patch audio into individual effects and out manually — chain reverb into delay or delay into reverb, or go wild with any order you like. No fixed signal flow, no wet/dry blend — just raw modular-style patching.

Ideal For:

Experimental sound design & electronic music production

Genres like Ambient, IDM, Glitch, Lo-Fi, Synthwave, Techno

Producers looking for a creative FX tool with full routing control

Modular fans wanting patch-style control inside a DAW
