Teia Synthesizers OpticShifter

Create morphing multipole resonances that sweep your synth tones into new dimensions with the OpticShifter from Teia Synthesizers, a 20-stage optical phaser for Eurorack systems. Phasers use multiple stages of all-pass filters to create resonant notches spaced across the frequency spectrum, carving new timbres from simple waveshapes. The OpticShifter features a selectable stage amount up to 20, making for an incredibly flexible effect to empower your sound design options. Introduce feedback with selectable stage count, letting you adjust resonance in the phaser tone to your taste from subtle to extreme.

Experiment with tweaking the large central Phase control, or use the onboard LFO to add immediate modulation to this crucial parameter. On the way into the effect, you can adjust input level and a tilt EQ to dial in the right amount of signal and focus in on the frequencies you want to process. A ping input allows you to pluck the phaser to create mallet-like percussive blips and bonks. Adjust the balance of the phasing effect with the dry/wet knob. Finally, OpticShifter features a variety of outputs including the main output, a feedback path output for pseudo-stereo operation, a wet-only output, and a unique comparator-based distortion path called Shred. If you crave sweepable space-age spectral shaping with maximum flexibility, the OpticShifter from Teia Synthesizers is a comprehensive solution for all your Eurorack phasing needs.
