Resonarium is in Alpha

Added 2025-06-08 16:03:03 +0000 UTC

I checked out Resonarium, a free and open-source physical modeling synth in a very early alpha state (v0.0.1). It's based on waveguide synthesis and resonators, capable of some wild and unpredictable sounds—so caution is key when using it. It’s flexible, modular, and surprisingly powerful despite its bugs and high CPU usage. It works with different excitation sources (impulse, noise, sequence, sample, external input), and its structure is clear if you understand waveguide synthesis.

Main Points:

Free & Open Source: Available on GitHub under GPL 3.0; binaries for Win/Mac, buildable on Linux.
Synthesis Method: Based on waveguide physical modeling with resonators and feedback.
Excitation Sources: Impulse, noise, sequence, sample, or external input audio.
Waveguide Taps: Each has 8 resonators with filter chains; customizable routing: parallel, interlinked, cascade.
Resonator Controls: Key tracking, pitch offset, decay (feedback), dispersion (harmonic spread), loop/post filters.
Modulation System: Built-in mod sources (LFOs, envelopes, step seqs) with modulation matrix; Bitwig mod integration possible.
Post FX Section: Filters, chorus, phaser, distortion, delay (tempo-synced), compressor, reverb, with poly FX options.
CPU Usage: High when using multiple resonators; UI sometimes buggy.
Warning: Unstable behavior and loud, screechy output possible—add a limiter after it.
Presets & Playability: Some included; very tweakable but not for the faint of heart.
