Theorem

Theorem is a wavetable synthesizer driven by mathematical expressions. It features a formula-based engine that turns equations into playable wavetables in real time. The sound can then be further sculpted with a low-pass filter, a unison engine, continuous 2D waveform morphing, built-in delay and reverb effects, and a flexible modulation matrix with two envelopes and LFOs.

But you don't need a math background to get great results. Some of the most interesting textures come from typing in random expressions and exploring what they produce.

Features:

• The formula based wavetable engine allows you to type mathematical formulas to generate waveforms. Use time domain to draw shapes from scratch or frequency domain to define individual harmonic amplitudes.

• Create evolving sounds by using y and z variables within your equations. This allows you to smoothly transition between different waveshapes using the Morph slider.

• All waveshapes are automatically band-limited to ensure high-quality, anti-aliased sound. This allows you to experiment with complex formulas without any digital artifacts.

• Stack up to seven voices in unison for massive leads and pads. Dedicated controls for detune and stereo spread allow you to add some thickness and width to your creations.

• A 2nd-order low pass filter provides classic subtractive synthesis, featuring modulatable cutoff and resonance alongside key-tracking.

• A flexible modulation matrix features two ADSR envelopes and two LFOs, making it easy to modulate the parameters.

• The BPM-synced delay allows you to create complex rhythmic effects.

• The reverb engine has adjustable room size, allowing you to add everything from tight resonances to ethereal atmospheres.

• The interface is designed for speed, keeping every control on a single screen so you can focus on the sound without having to dive through menus.

• A real-time visualizer provides immediate feedback on your formulas, showing exactly how they are affecting the waveform.

• Includes a preset browser with the built-in presets, as well as the possibility to save and load new presets.
