DelayU-42
Key Features
- Vintage-style digital delay voice focused on dark repeats, grit, and 80s rack-delay character
- Input, Output, Mix, Feedback, and delay-time controls keep the workflow direct for send effects and delay throws
- Raw millisecond timing and host-synced clock mode cover both manual slapbacks and tempo-locked rhythmic echoes
- Cascaded filtering progressively darkens repeats so delay tails sit behind vocals, guitars, and lead sounds
- Modeled dual opto-limiter lets feedback push harder while smoothing transients instead of clipping harshly
- Feedback and delay time can be pulled down to use the plugin as a saturation and limiter color box
- Version 1.1.1 adds denormal protection, safer sample-rate allocation, DSP stability fixes, and in-plugin PDF documentation access
Description
DelayU-42 is a vintage-style digital delay from MKS Mixing, built around dark echoes, input-driven saturation, and limiter behavior rather than clean utility repeats. It aims for the character of classic 80s rack delays while keeping the front panel simple enough for fast vocal throws, guitar echoes, synth sends, and mix effects.
The core controls are Power, Input, Output, Mix, Feedback, and delay time, with raw millisecond timing or host-synced subdivisions. BPB reports a range up to 4800 ms in delay mode, while the official page highlights cascaded filtering that pushes each repeat darker so tails sit behind the dry signal instead of masking it.
DelayU-42 is also useful when you do not need an obvious echo. With Feedback and delay time pulled down, the Input and Mix controls can turn it into a quick saturation box, using the modeled dual opto-limiter to smooth aggressive transients and add grit without clipping.
Version 1.1.1 ships as direct Windows and macOS ZIP downloads. The Windows archive contains a VST3 build, while the macOS package includes VST3 and AU components plus an installer script for clearing quarantine flags, applying a local code signature, and refreshing DAW plugin caches.
Frequently Asked Questions
Can DelayU-42 work as more than a normal echo?
Yes. BPB notes that setting Feedback to 0 and delay time to 0 ms lets the Input and Mix controls act more like a saturation and limiter stage than a traditional repeat effect.
What makes the repeats sit behind the dry sound?
The official page and BPB both point to cascaded filtering as a core part of the sound. Each repeat darkens progressively, which helps vocal and lead delays create depth without fighting the original signal's top end.
Does the feedback get harsh when pushed?
DelayU-42 models a dual opto-limiter in the feedback path. That lets feedback move toward more aggressive or self-oscillating behavior while smoothing transients instead of collapsing into brittle digital clipping.
What is included in the current downloads?
The Windows ZIP contains the DelayU-42 VST3 folder, documentation, and a README for version 1.1.1. The macOS ZIP contains a nested release package with VST3 and AU builds, documentation, and an installer command script.
