About this item

Create remarkable sounds and sequences with the Polyend Synth, a 3-part multitimbral multi-engine synthesizer that operates with up to 3 synth engines simultaneously. Each of the eight engines utilize a wide variety of synthesis techniques to deliver a wide spectrum of tones and textures.

VAP

VAP is a virtual analog polysynth, boasting a dual-oscillator architecture and a versatile modulation matrix. Complete with multiple filter flavors and pulse width modulation, VAP allows you to sculpt intricate patterns. This engine shines when it comes to creating mesmerizing, evolving textures, crafting lush pads, and conjuring up one-of-a-kind sound effects.

PHZ

With PHZ classic phase distortion tones or experimental new sounds are possible. PHZ consists of 2 oscillators with varying shapes and unlike classic phase distortion synths, filters, and a Polyend-style mod-matrix have been included. The phase of an input waveform is distorted by functions/methods. Each of these functions can be gradually modulated by parameters X and Y, ranging 0 to 1.

WAVS

Wavs is a unique wavetable synthesizer engine, which plays and morphs between two wavetable oscillator samples while applying filtering. Wavetables are stored in plain WAV files in the Samples > Wavetables folder. Control of Position controls the scanning while it interpolates between the WAVs. Warp affects the oscillator phase, stretching or warping from the center to the edge of the sample point. This operates in a positive or negative dimension.

FAT

FAT is a powerhouse synth engine that epitomizes the lush, vintage warmth of classic analog synthesizers. At its core, FAT hosts three virtual analog oscillators and offers an intuitive drift and detune control, ensuring you can effortlessly sculpt iconic massive sounds. The presets contain two distinct flavors of ladder filters inspired by two unique analog classics. It offers a versatile range of sounds, from deep reese basses to ethereal pads, expressive leads and classic keyboards.

WTFM

WTFM is a unique 2-operator FM synth engine that utilizes wavetable based oscillators driven by a 3x feedback system. The operators are based on sweeping wavetables, ranging from fundamental sinewaves to harmonically rich timbres, offering a diverse tonal palette. Whether you're sculpting smooth, enveloping pads or crafting cutting-edge metallic tones, WTFM empowers you to achieve unique textures with precision and authenticity.

PMD

Classic Physical modeling synthesis with unique controls and modulation options. Timbre controls the sound in a way specific to each generator. Mallet and Airflow are specific parameters for each generator. The Exciter envelope should not be treated as an equivalent of amp envelope in a traditional synth—its behavior has different effect on each generator (does not affect Strike at all). The Resonator further shapes the mixed sound of the generators.

Grain

Grain is a granular synth engine, which takes a standard WAV sample file and generates a series of audio fragments called grains. The generation of the grains such as size, density, and shape can be controlled, along with how the grains are scanned and played back (for example scanning position and direction). The cloud and burst features allow you to control how grains are generated—continuously or in cyclic batches of grains. Grain pitch can be played in paraphonic mode as chords.

DEL

Dual delay lines with five unique models, giving you the flexibility to sync with your track or create complex delay effects.

REV

Three reverb modes—Natural, Plate, and Warp—let you add anything from subtle space, to massive otherworldly reverbs.

Musical Smart Grid for Live Play

Stay in control even during the most chaotic performances. The customizable Smart Grid ensuresevery note and chord stays in the desired scale, while making live performances smoother and more intuitive.

Scenes on Demand

Imagine having every setting from synth engines to sequences saved in one easy-to-recall Scene file. Build entire live sets and instantly access them with a touch. Plus, share your unique setups with the community.

Combo Knobs for Quick Tweaks

Create dramatic builds or subtle shifts with customizable combo knobs. Whether controlling one or all three synths at once, adding movement and dynamics to your sound has never been easier.

Polyphonic Aftertouch

Express every nuance of your performance with polyphonic aftertouch. Adjust multiple parameters with the pressure of your fingers allowing for truly expressive, dynamic control over your sounds.

Real-Time Visual Feedback

Every adjustment you make is instantly reflected in the visual interface, giving you clear, real-time feedback on how your sound is evolving. Whether you're tweaking filters, modulating oscillators, or adjusting LFOs, you'll see the changes happen as you hear them.

Endless Customization

Expand your creative palette with SD and USB storage. Easily load new wavetables, presets, and entire setups, or share your creations with others. With endless possibilities, this synth is designed to grow with you.
