reFX Introduces Rippler Physical Modeling Synthesizer


reFX, the developer behind the Nexus virtual instrument, has announced the release of a new hybrid software synth that brings together physical modelling and subtractive synthesis with a broad array of additional features and capabilities.

Rippler is a software synthesizer built around a combination of modal synthesis and subtractive synthesis techniques.

Physical modelling synthesis is a technique that can emulate the acoustic properties of physical objects and instruments, or be pushed to create experimental sounds that reimagine real-world timbres in new and creative ways.

The instrument uses banks of resonators to generate sounds without samples, with bi-directional energy coupling between resonators and two independent synthesis layers. Each layer can use parallel or serial resonator routing, with additional oscillators, filters, modulation sources, and effects processing.

In its Exciter section, Rippler gives you the choice of 32 onboard samples, user-imported samples, sidechain input or a custom impulse editor to shape its initial signal, and there’s also the option to use a noise generator to feed the resonators, alongside the exciter or on its own.

These run into dual resonator modules, which feature a choice of 12 models that simulate different acoustic instruments and objects: String, Beam, Squared, Bell, Membrane, Plate, Drumhead, Djembe, Vibraphone, Marimba, Closed Tube, Open Tube. These can operate in parallel or in series, the latter mode using bi-directional coupling to let the two resonators exchange energy as they would in an acoustic instrument.

There’s also a Manual resonator mode that replaces the physical model with a custom partial series that can be drawn in by hand, and lets you store resonator configurations as snapshots and morph between them in real time.

Rippler is also equipped with two conventional oscillators with Phase, Fold and Asymmetry controls that can be layered with its physically modelled output to “blend, enhance or solidify your sound”. Both these and the physical modelling engine pass through dual filters, which offer a choice of 27 filter types spanning low-, high-, band-pass and notch filters with multiple slopes, along with vintage-style models, ladder types and a formant-shifting Vowel filter.

This entire signal path can be duplicated, giving you two layers each made up of dual resonators, oscillators and filters, all running into the effects and master output. Rippler features a broad selection of 13 effects covering delay, reverb, chorus, compressor, distortion and more, which can be applied per-layer or globally. There’s also a sophisticated arpeggiator and sequencer onboard with modifier lanes that introduce variation to pitch and velocity.

Rippler supports MPE, aftertouch, micro-tuning, MIDI tuning systems, and audio input routed into the resonator system.

Features:

  • Modal synthesis engine using banks of resonators to generate sounds without samples
  • Bi-directional energy coupling between resonators
  • Dual-layer synthesis architecture with parallel and serial resonator routing
  • Two oscillators and two filters per synthesis layer
  • Twelve acoustic models based on mathematical formulas and FEM analysis

  • Multiple modulation sources can be assigned to parameters
  • Drag-and-drop modulation routing system
  • Custom modulation response curves using Mod Mapping
  • Modular effects architecture with 13 master effects and 12 effects per layer
  • MPE support with per-note pitch bend, pressure, and slide control
  • Aftertouch support
  • Micro-tuning support using Scala .scl and .kbm files
  • MIDI Tuning Standard (MTS) support
  • Audio input routing into resonators synchronized with played notes
  • Manual Mode for user-defined tuning and resonator configurations
  • 441 sound presets
  • 32 exciter samples
  • 10 arpeggiator presets
  • 64 LFO shapes
  • Available as Audio Unit, VST3, and AAX plugin formats
  • Compatible with macOS and Windows systems

Rippler is descended from RipplerX, a free and open-source physical modelling synth from developer Tiagolr, who has partnered with reFX to develop and release a commercial successor.

reFX Rippler is available now for $99 USD (normally $129).

 

Free Software Synth Recreates Nintendo FDS Chiptune Sound


Magical FDS Plug is a free and open-source software synthesizer plug-in, for Mac and Windows, that reproduces the sound of the Nintendo FDS sound chip.

Here’s what they have to say about it:

“The FDS sound chip features a unique architecture in which a 64-sample waveform memory (carrier) is modulated by a separate 32-step instruction sequence (modulator).

Magical FDS Plug preserves the full flexibility of the original hardware, while providing a logical interface for building waveforms — through additive synthesis, presets, and more.”

Features:

  • Carrier + Modulator — two independent signal paths. Design the audible waveform (carrier) and its modulation sequence (modulator) separately.
  • Logical waveform editing to take the guesswork out of FDS sound design:
    • Additive Synthesis — Drawbar-style, like a tonewheel organ. Mix harmonics with 8 sliders.
    • Preset Waveforms — Start from triangle, sawtooth, or sine wave, then reshape the tone via compression and expansion.
    • Pulse Waveform — Shape the waveform by adjusting the pulse width (1–63) of a square wave.
    • Freehand Drawing — Draw a 64-point waveform directly using sliders.
  • Modulator: 6 presets + Custom — Triangle, sawtooth, sine, square, ramp up, ramp down. In Custom mode, enter a 32-step opcode sequence (32 digits, 0–7) as text.
  • Modulation rate modes — Three modes: LFO (slow, cyclic modulation), FM (timbral modulation), and OFF.
  • ADSR envelopes for both carrier and modulator — Shape the volume and modulation over time, with the same workflow as Magical 8bit Plug 2.
  • Hardware-accurate output filter — A ~2 kHz low-pass filter modeled on the original hardware, switchable on/off (default: on).

Magical FDS Plug is available now as a free download.
