KV331 Audio Synthmaster Standard Bundle

What SynthMaster Producer Bundle Is For

KV331 SynthMaster Producer Bundle is an all-in-one solution for sound creation in the studio, designed for producers who want to cover as much ground as possible without multiplying instruments. Whether you compose EDM, pop, hip-hop, film music, or ambient, you have an arsenal of ready-to-use sounds (leads, basses, pads, plucks, keys, FX) and a synthesis engine deep enough to design your own patches, from the most organic textures to the most modern timbres.

Main Features

SynthMaster 3: "all-around" synthesis and SFZ playback

SynthMaster 3 is KV331 Audio's flagship synthesizer, designed as a complete synthesis platform: VAnalog, Additive, Vector, Wavetable, Granular, Phase Modulation, Phase Distortion, Frequency Modulation, Pulse Width Modulation, Ring Modulation, Physical Modeling, and SFZ sample playback. This diversity allows you to go from a powerful analog sound to evolving pads, cinematic granular textures, or hybrid sample+synthesis instruments, all within a single environment.

Modular architecture and stackable layers

Each instance can contain up to 16 Layers. Each layer can host up to 16 modules and up to 32 modulation sources, with the ability to duplicate layers and modules to speed up design. The routing tab offers a clear view of the audio flow and facilitates adding, removing, enabling/bypassing, and creating connections between modules, to build a patch progressively and logically.

Multiple views for a production-oriented workflow

SynthMaster 3 offers three editing modes to maintain clarity even on complex patches: Layer View (editing a single layer), Track View (keyboard/velocity zones, voicing, unison, arpeggiator/sequencer across multiple layers), and Mix View (insert FX and FX sends). The result: you seamlessly switch from synthesis to internal mixing without breaking your flow.

Granular Oscillator: textures, movement, and sound design

The granular oscillator applies granular synthesis to a sample, a multisample, or a wavetable. It can run up to 16 voices, each with up to 32 grains (up to 512 grains total per oscillator). Spread and randomization parameters (volume, pan, detune, position, grain length, timing, playback direction) provide access to lively pads, drones, transitions, and organic FX.

VAnalog Oscillator: analog character and quality control

The new VAnalog oscillator generates its waveforms in real time via curve segments, with shapes inspired by well-known analog synths. It offers 2 morphable waveforms plus an independent sub oscillator. A quality parameter adjusts the oversampling level to control aliasing, useful both in sound design and "ready-to-mix" production.

Modern FX and filters: waveshaper, polyphonic phaser, formants

To sculpt a sound without multiplying external plugins, SynthMaster 3 includes a Waveshaper with many algorithms (Soft Tanh, Soft ATan, Heavy, Fuzz, Fold, Rectify, Clip, Bitcrush) and a Custom mode allowing you to draw your own curve (symmetrical or asymmetrical). On the filter side, the Phaser Filter acts polyphonically (per voice) for rich movement, and the Formant Filter simulates vowels by morphing between formants, perfect for vocal leads, talking pads, and articulated FX.

Expressive modulations and per-layer arpeggiator/sequencer

Modulations include ADSR, multi-stage envelope, LFO, Step LFO, as well as a Noise LFO capable of producing various noises (white, pink, brown, violet, blue) with sample & hold, bit reduction, and follower envelope. The Scaler module (evolution of Keyscaler) can use another source as input and act as a modulation waveshaper. Each layer has its own sequencer and arpeggiator, with possible random values per step (trigger/hold/slide) and MIDI output per layer to route patterns to different DAW tracks.

Preset management and content creation (waveform, wavetable, multisample)

The preset browser offers advanced search by product, author, bank, instrument type, attributes, styles, and name, with upward compatibility for SynthMaster One and 2 content (if installed/activated). For deeper editing, SynthMaster 3 includes a Waveform Editor (single-cycle creation via curve segments or freehand drawing with spectrum editing), a Wavetable Editor with 7 effect families (Spectral Filter, Waveshaper, Modulator, Bender, Shifter, LoFi, Sync) and WAV export (2 to 256 frames), as well as a Multi Sample Editor via drag-and-drop (WAV/AIFF) with SFZ export.
