Husserl2 is a powerful 32-voice synthesizer designed to deliver a rich and complex sound experience. It features an advanced waveset engine with 44 distinct wavesets, including filter sweeps, morphs, and harmonic bundles, all accessible through a dual-axis spline-interpolated waveform system. The synthesizer includes two oscillators with extensive modulation options such as phase, ring, and frequency modulation, combined with gate and oscillator sync controls. The 5D state-variable filter offers flexible cutoff and resonance settings, multiple pole and filter type mixes, and 4x oversampled saturation, enabling a nearly limitless sonic palette.

Optimized for performance, Husserl2 runs as a standalone application that utilizes all CPU cores on your machine, enhancing its processing capabilities. It supports native, ASIO, and ReWire drivers to ensure seamless integration with popular DAWs. The internal modulation matrix is extensive, featuring 151 modulation sources and 143 destinations, including envelopes, LFOs with multiple waveforms, sample and hold, and an XY pad for complex modulation routing. MIDI support is comprehensive, with 120 mapped controllers, pitch bend, mod wheel, velocity sensitivity, and a built-in MIDI file player. The interface is resizable and includes real-time visual feedback for waveforms, filter curves, and modulation values.

Husserl2 is available as a completely free synthesizer, with no registration or email required for download. Its open-source roots allow users to explore and modify the instrument if desired. The synth also includes a preset manager for easy saving and loading of sounds, plus a variety of demo presets to get started. While it is recommended to use higher sample rates for the best audio clarity, especially in higher octaves, Husserl2 delivers professional-grade quality suitable for a wide range of musical styles. Its rich feature set and dedication to quality make it an excellent choice for producers seeking a high-performance synth without cost.
