Toybox Audio Thump One 3.0: Free Dual-Layer Synth Plugin Update
Toybox Audio Thump One 3.0 is a free dual-layer synthesizer plugin designed for hard-hitting sounds like kicks, basses, and leads. The latest 3.0 public beta update introduces new features and refinements to the original free plugin, available for macOS and Windows. No sign-up is required to download the beta.

What’s new in Thump One 3.0
Thump One 3.0 beta expands the plugin’s sound design capabilities with several notable additions. The update introduces a new MIDI strip hidden behind the keyboard section at the bottom of the GUI, providing streamlined access to MIDI processing tools. The dual-layer engine remains unchanged: the Kick layer features a wavetable oscillator based on analog kick drum samples, complete with saturation, filter, and a buzzy circuit emulation for broken-speaker textures. The Layer section emulates the Roland JP8000 Supersaw oscillator, offering modes like FM, dirt, fifth, noise, and squelch for expanded timbral control.
The built-in modulation system gains a multi-segment modulator per parameter and an AR envelope, enabling complex, evolving sound design. The update also polishes the GUI and workflow, maintaining the plugin’s distinctive visual identity across Toybox Audio’s synth lineup.
