Spectrus: Modular Multi-FX Plugin with 9 Reverbs

Morphulus has officially launched Spectrus, a new modular multi-effect plug-in designed for extensive audio processing. This innovative tool features a robust 4-slot parallel/serial processing architecture, enabling users to craft complex effect chains with ease. Furthermore, Spectrus comes equipped with a total of 21 studio-grade effects, providing a versatile palette for sound design and mixing tasks. Notably, the plug-in distinguishes itself with nine purpose-built reverb algorithms, each employing a distinct DSP topology to offer a wide range of spatial effects.
Deep Dive into Reverb Algorithms
The reverb section of Spectrus is particularly comprehensive, offering a variety of unique algorithms. For instance, the Plate reverb utilizes an 8-delay FDN with a Householder matrix, delivering classic plate characteristics. In addition, Prism employs mathematical sequence-based delay patterns, which include transient-shaping attack control for precise sound sculpting. Bloom, another notable algorithm, is a 6-delay feedback network chamber reverb, ideal for creating rich, resonant spaces. Moreover, Ember features a 16-delay FDN with per-delay-line harmonic processing across five coloration modes, allowing for intricate textural variations. Shimmer introduces granular pitch-shifted feedback, complete with an optional dual-voice mode for ethereal effects. Glacier provides a plate-style FDN freeze reverb, while Freeze offers infinite-sustain capture with input bleed, perfect for layering sounds. Lastly, Velvet Room combines sparse early reflections with a Dense Velvet Noise late tail, and Velvet Hall pairs a DVN early section with a 16-delay Hadamard FDN for extended, spacious tails.
Flexible Modular Architecture
Spectrus routes audio through its four parallel processing slots, also offering serial routing options to maximize flexibility. Each of these slots is capable of loading any of the 21 available effects, which encompass more than just reverbs. The library includes eight modulation effects, such as Chorus, Vintage Chorus, Flanger, Phaser, Tremolo, Ring Modulator, Rotary, and Sample and Hold. Furthermore, three distinct delays are provided: Echo, Tape Delay, and Spectral Delay, alongside a versatile Saturator for adding warmth and grit. Each slot within Spectrus boasts independent level control, a wet/dry mix knob, and mute/solo functionality. Users can also copy/paste effects, reposition chains, and lock slots for comparative auditioning, streamlining the workflow considerably.
