Trebless has released Tesseract Echo, a free, tweakable Multi-Tap Magnetic Tape Delay and FDN Reverb.
Engineered for zero artifacts and maximum character, Tesseract Echo relies on Hermite 4-point interpolation, constant-power panning, and dual-stage diffusion to deliver pristine, wide, and deep spatial effects.
Features:
- 4-Head Tape Engine: Independent level and pan controls per head, with fractional spacing algorithms.
- Non-Linear Tape Filter: 1 pole Highpass and Lowpass filters, and an analog-style Drive stage inside the feedback loop with automatic makeup gain.
- Advanced Modulation: Push into audio-rate modulation or use the "Tape" (Wow & Flutter) and "Stepped Random" LFO shapes for mechanical degradation.
- Karplus-Strong Engine: Tune the delay time to incoming MIDI notes to synthesize physical strings and tuned resonances.
- FDN Reverb & Ducker: A pristine Feedback Delay Network reverb with selectable routing, plus a built-in sidechain compressor to duck the wet signal against the dry input.
Availability
Tesseract Echo is available for macOS, Windows and Linux in VST3, AU, AAX and LV2 plugin formats.
