Freqlux

The Hotone Freqlux is a stereo digital pitch shifter featuring three independent pitch-processing engines that can operate simultaneously. Each voice supports five modes: PolyShift for polyphonic pitch shifting, KeyTrack for scale-based harmonization, Detune for micro-pitch effects, ARP for arpeggiated pitch sequences, and Mod Only for modulation without pitch shifting. Individual voice parameters include Level, Pan, Tone, Attack and dedicated effects such as modulation, tremolo, feedback and drive. The Flux footswitch enables pitch glides with adjustable curves, while Auto Flux provides automated pitch movement. Additional features include 32-bit processing, approximately 4–5 ms latency in drop-tuning applications, 100 factory presets, 200 user preset slots, expression pedal and MIDI support, USB-C connectivity, an LCD display and selectable preset or real-time control modes. The pedal operates on 9V DC.
