Polymode by Cherry Audio

Overview

This instrument is designed to deliver massive, evolving textures that go far beyond traditional subtractive synthesis. Its architecture emphasizes movement, depth, and harmonic complexity, making it especially effective for lush pads, animated strings, and choir-like sounds.

By reimagining a historically important design, it preserves the character of the original while removing its practical limitations and extending its creative scope for modern production.

Paraphonic Architecture

At the core is a paraphonic design that treats groups of voices through shared filtering stages. This approach creates a distinctive, unified motion that differs from conventional fully polyphonic synthesizers.

Key characteristics include:

• Multiple voices sharing filter behavior
• Natural phase interaction between notes
• Thick, ensemble-style sound generation
• A character that feels cohesive and organic

This architecture is central to the instrument’s signature sound.

Oscillators and Mode Filters

The oscillator section provides layered waveforms that form the basis of its dense tonal character. These signals are shaped by unique “mode” filters that contribute strongly to its recognizable timbre.

Core elements include:

• Simultaneous saw and pulse waves
• Accurately modeled mode filters
• Parallel filtering paths for complex tone shaping
• A classic ladder-style filter for final sculpting

Together, these stages produce sounds that feel wide, animated, and harmonically rich.

Modulation and Animation

Movement is a defining strength, supported by an unusually broad set of modulation routings. Nearly every major parameter can be animated, allowing subtle motion or dramatic evolution over time.

Modulation features include:

• Multiple LFOs with tempo sync
• Modulation sources such as velocity, pressure, and noise
• Deep routing flexibility for dynamic patches
• Smooth transitions suited for long-form textures

This makes the instrument ideal for pads that evolve continuously without sounding repetitive.

Resonators and Effects

An expanded resonator section adds further tonal shaping and spectral emphasis, enhancing the sense of size and complexity. Integrated effects complement the synthesis engine and help finalize sounds internally.

Included processing covers:

• Resonator modes with variable slopes and notch options
• Ensemble and tri-chorus effects for width
• Phaser, tempo-synced delay, and reverb
• Classic string-machine-style modulation

These effects are especially effective for creating cinematic and atmospheric layers.

Presets and Musical Applications

A curated preset library demonstrates the instrument’s strengths across a range of styles. Presets are designed to showcase movement, depth, and expressive potential.

Common use cases include:

• Lush pads and evolving soundscapes
• Vintage-inspired string ensembles
• Choral and vocal-like textures
• Ambient, cinematic, and progressive music

Overall, this synthesizer stands out as a texture-focused instrument that prioritizes motion, density, and character, making it a strong choice for producers seeking expansive and expressive polyphonic sounds.
