What's Under the Hood

Everything from PolyBLEP oscillators to diode clipping, zero-delay-feedback filters, and a reactive roasting chicken UI.

🎛
PolyBLEP Oscillators
Square with PolyBLEP alias suppression, Triangle, and a 2-operator FM engine. Lush detuned stacks or single crisp tones.
ANTI-ALIAS
🔥
Saturation & Grit
Diode-clipper drive stage modelling analog hardware warmth, plus a hard clipper for digital aggression.
ANALOG MODEL
💀
Bitcrush & Degradation
Variable-depth Bitcrushing and Sample-Rate Reduction (sample & hold decimator) for lo-fi textures from cassette to N64.
8-BIT VIBES
🌊
ZDF Filter
Zero-Delay-Feedback StateVariableTPTFilter for true analog-modeled resonance. No quantisation artefacts at any cutoff.
ZERO DELAY FB
🎚
LFO Routing Matrix
Global LFO with Sine, Triangle, Square & Random-step shapes, routing to filter cutoff and FM index for evolving, living tones.
4 SHAPES
🎹
Full MPE Support
Per-note pitch bend, pressure → FM growl & amplitude, timbre → pulse width. Built on juce::MPESynthesiser with legacy MIDI fallback.
MPE EXPRESSIVE
⚡
4× Oversampling
Saturation, drive, and clipping stages wrapped in juce::dsp::Oversampling — up to 4× to eliminate all aliasing artefacts.
OVERSAMPLED
🐔
Roasting Chicken UI
A 30-frame embedded sprite sheet animates from raw to charred, driven by a real-time RMS envelope follower in processBlock().
REACTIVE UI
💾
APVTS State Management
All parameters managed by AudioProcessorValueTreeState — full host automation, DAW state recall, and XML preset serialisation.
