Equations

Equations is a unique synthesizer plugin that puts the power of mathematical expression directly at your fingertips. Instead of selecting from preset waveforms, you write your own equations to generate completely unique sounds. Whether you're a sound designer seeking unprecedented sonic possibilities or a music producer looking for fresh, distinctive textures, Equations Synth opens up an infinite universe of waveforms limited only by your imagination.

The Power of Mathematical Sound Design

At the heart of Equations Synth is a sophisticated equation parser. You can type in any mathematical expressions using x as your input variable, and watch as your formula transforms into audio in real-time. Access a comprehensive library of mathematical functions including:

• Trigonometric functions: sin, cos, tan, sec, and their hyperbolic variants.
• Exponential & logarithmic: exp, log, log10, sqrt, and more.
• Special functions: abs, floor, ceil, round, sgn, frac.
• Advanced operations: Complex mathematical expressions with full operator support.

The built-in calculator-style interface makes equation entry intuitive, while the real-time graph display lets you visualize your waveform before you even hear it.

Deep Sound Sculpting Tools

Dynamic Equation Parameters:

• Four customizable parameters (A, B, C, D) that can be referenced in your equations, each with adjustable ranges.
• Graph manipulation controls: X Scale, Y Scale, and X Offset for precise waveform shaping.
• X Mirroring modes for creating symmetrical waveforms with positive or negative reflection.

Classic Synthesis Features:

• Pitch controls: Coarse (semitones) and Fine (cents) tuning.
• Integrated Multimode filter with cutoff and resonance controls.
• Noise generator blendable with equation-based waveforms.

Comprehensive Modulation System

Bring your equations to life with an extensive modulation matrix featuring:

Modulation Sources:

• 3 Envelopes (ADSR) with tempo sync options.
• 3 LFOs with multiple waveform shapes (sine, square, saw), tempo sync, and delay.
• Note Velocity for dynamic expression.
• Modwheel for performance control.
• MPE Support: Timbre and Pressure for expressive multi-dimensional control.

Modulation Destinations: Route modulation to virtually any parameter including:

• Volume, Pitch (Coarse/Fine).
• All Equation Parameters (A, B, C, D).
• Graph parameters (Scale X/Y, Offset X).
• Filter Cutoff and Resonance.
• Noise Level.
• Effect parameters (Chorus, Delay, Reverb, and more).

Effects Chain

Polish your equation-based sounds with a professional effects suite:

• Delay: Stereo offset, feedback, tempo-synced timing.
• Harmonic Reverb: Room size, damping, and mix controls.
• Chorus: Modulation depth and rate.
• Tape Simulator: Wow, Flutter, Saturation, as well as various tape player emulations.

Intuitive Interface Design

Inspired by classic calculator aesthetics, Equations Synth features:

• LCD-style display showing equation input and real-time waveform visualization.
• Tabbed interface organizing Equation, Synth, Modulation, Effects, and Note settings.
• Integrated help system with context-sensitive guidance.
• Virtual MIDI keyboard for quick auditioning.
• Scalable, resizable window.
• Preset management system for saving and recalling your creations.

Advanced MIDI & MPE Capabilities

• MPE (MIDI Polyphonic Expression) support with configurable channel count.
• Adjustable pitch bend ranges (global and per-note).
• MIDI input channel selection.
• MPE-aware modulation for expressive performance.

Advanced Tuning Capabilities

• Support for KBM and SCL scale loading.
• Support for MTS-ESP.
