DELOS R
An 8-line FDN reverb with spectral decay control.
Overview
DELOS R is built around an eight-delay-line feedback delay network. Its diffusion and feedback structure creates a continuous algorithmic tail while keeping the early build-up, spatial field and modulation behavior under direct control.
A five-band decay-rate section changes how long each frequency region remains inside the feedback network. This is different from filtering the wet output: low, low-mid, mid, high-mid and high energy can decay at different rates, allowing a dark room, controlled low-end bloom or extended high-frequency air without relying on post-EQ alone.
Pre-delay, size, diffusion, width, modulation, wet/dry balance and output metering form the main signal path. A post-reverb equalizer remains available for final tonal placement after the decay behavior has been established. Host-negotiated multichannel and surround configurations extend the same decay architecture to immersive and multiple-output production workflows.

- Size, 0.1–20 s decay, 0–200 ms pre-delay, diffusion, damping and width
- Modulation depth/rate, post low/high shelving, wet mix and A/B comparison
Formats
Mono, stereo, multichannel and surround bus configurations · Host-negotiated multiple-output operation · Frequency-dependent decay inside the feedback network · User preset save, browse and category system · AU · VST3 · Standalone · Unity · Apple Silicon, Intel macOS and Windows support

Interface & workflow
Decay Rate EQ
Five frequency regions scale decay time inside the feedback network rather than simply equalizing the wet output.
60 factory presets
Six acoustic categories with ten production-focused variations per category, plus user preset storage and A/B comparison.

Release status
Pre-release · Final testing
DELOS R has not yet reached its commercial release. Compatibility, performance and preset validation remain in progress ahead of the planned release on 5 October 2026.
Anyone who registers and downloads an available DELOS build before 5 October 2026 will receive one additional DELOS plugin at no charge when the release catalogue becomes available. Eligibility is linked to the registration email address.
Latest release notes
What changed in DELOS R
- Fixed the macOS build's minimum OS requirement, which had accidentally been raised to macOS 15.2 (Apple Silicon only) — now macOS 10.13+, Intel and Apple Silicon
- Redesigned Early Reflections to remove an unintended slapback-echo character
- Fixed a phase-coherence issue in the diffusion network
- Fixed aliasing in the modulation LFO voices
- Corrected factory preset pre-delay and mix values
- Added Drums, Vocals, Synth, Strings and Guitars preset categories
- The active preset's name now persists when the plugin editor is closed and reopened
