FilterShaper Core by Cableguys

FilterShaper Core Overview

FilterShaper Core is a creative filter effect designed for producers who want classic analogue character combined with modern, tempo-synced modulation. Rather than applying static filtering, it allows cutoff and resonance to move rhythmically, dynamically, and musically in sync with your track.

Running inside ShaperBox, FilterShaper Core integrates seamlessly with other Shaper effects, making it easy to build complex, layered processing chains while maintaining a clear and consistent workflow.

Analogue Sound Engine

At the heart of FilterShaper Core is a high-quality analogue-style filter design:

• Zero-delay feedback (ZDF) filters for natural response
• Resonance compensation to maintain balance at all settings
• Internal saturation for warmth and character

This architecture ensures the filter remains musical and stable, even during fast or aggressive modulation.

Filter Types and Character

FilterShaper Core includes a wide range of filter modes:

• Classic low-pass, high-pass, band-pass, notch, and peaking filters
• Clean, precise modes for transparent shaping
• Warm and driven modes for colour and saturation

Advanced resonance options allow you to keep things controlled or push the filter into self-oscillation for expressive, aggressive effects.

Drawable Modulation

One of FilterShaper Core’s defining strengths is its visual modulation system:

• Draw custom LFO shapes for cutoff and resonance
• Sync modulation precisely to beats and bars
• Create anything from subtle movement to dramatic filter sweeps

This makes rhythmic filtering intuitive and fast, turning modulation into a creative design tool rather than a technical obstacle.

Dynamic and Audio-Driven Control

Beyond LFOs, FilterShaper Core responds directly to audio:

• Envelope followers dynamically react to input level
• Increase cutoff as sounds get louder or emphasize resonance on decays
• Adaptive release for smooth, analogue-like behaviour

These tools make FilterShaper Core especially effective on drums, basslines, and rhythmic synth parts.

Multiband Filtering

FilterShaper Core supports up to three frequency bands:

• Apply different filter types to lows, mids, and highs
• Enhance clarity by treating each range independently
• Create complex movement without overwhelming the mix

Each band includes its own mix control, allowing precise balance between processed and dry signal.

Workflow and Integration

Designed for speed and clarity, FilterShaper Core includes:

• A resizable, high-resolution interface
• Preset waveforms for common modulation patterns
• Smooth bypass and master mix for clean transitions

Used alone or combined with other Shapers, it fits naturally into both creative sound design and practical mixing workflows.

Typical Use Cases

• Rhythmic filter pumping on drums and loops
• Animated movement for synths and basslines
• Subtle analogue-style tone shaping
• Creative transitions, builds, and breakdown effects

FilterShaper Core blends analogue warmth with modern modulation, making filtering an expressive and rhythmically alive part of your production.
