FreeqS

Overview

Engineered for root notes, live keys, and clean frequency moves.

FreeqS is a frequency shifter with a second, musical path when you need intervals that stay in pitch. Classic Bode-style shift for the sound known from classic frequency shifting; Pitchshifters mode when you want real semitone moves. Built for DJs, producers, and anyone who dabbles in frequencies.

Detect the key of what you hear, park a system note, aim Set Key, nudge fine cents, and move. Confidence keys show the runners-up when the material is messy. Material modes for single tones or busy loops. Lean GUI, permanent insert energy – same family as the rest of EarthGuest Audio.

Custom Mode maps the shift control to the range you care about – full open when you want everything, or a tight window around the area you’re hunting – so the knob always feels full-scale and useful, whether you’re working a narrow +/- few Hz or a wide performance throw. Perfect for all ranges, and a blast
with hardware: MIDI learn a controller or mixer knob, spin FreeqS like a dedicated tool, freeze a layout for the gig, and ride it as hard as the set needs without fighting a full +/-5 kHz sweep for a three-semitone move.

Optional Pitchshifters mode (~120 ms latency) when quality musical transpose matters more than near zero-delay. Toggle off and you’re back on the classic low-latency Bode path. Soft fade when switching modes so you don’t click the world in half.

MotionRec adds internal automation timelines – record, play, and ride FreeqS’s main controls as session motion, export/import as .more, without depending on host automation lanes for every knob.

Primarily designed for live use, stems, DJ setups, and creative harmonic moves in the DAW. Controllers welcome. MIDI can drive Set-to-Key. CPU stays polite.

Authorized for live use in real situations.

Core Features

Classic Frequency Shift (Bode)

– Adds or subtracts Hz across the spectrum – the classic frequency-shifter character
– Low-latency path for live and tight DAW use
– Huge shift range (-5 kHz … +5 kHz) for subtle pull or extreme outerspace

Pitchshifters Mode

– True musical pitch change (ratio / intervals), not pure +/-Hz
– Spectral HQ path when the mode is on (~120 ms latency)
– Soft fade when switching modes

Custom Mode

– Map the frequency / pitch control to any useful range – not only full +/- extremes
– Full-scale feel on the knobs or encoder within that window
– Ideal for controllers and mixers (MIDI learn / hardware ride)
– Narrow for fine surgery or wide for big performance sweeps

– Optional mapping curves and freeze-friendly step layout for gigs and “set and ride” setups
– Original mode keeps a full +/-5 kHz throw with optional fine-zone splitters around centre

Key Detect

– One-button DETECT KEY over your chosen listen length (bars / beats / custom / auto)
– Hold to listen longer; finish early or latch when you need hands free
– Material: Auto * Single note * Mix / loop
– Band focus: Full * Octave 3 * Octaves 3 & 4

– Confidence keys – alternate candidates with relative strength
– Key from Bass option for low-root material

– Detect cents for fine tuning of the detected pitch

System Key & Set Key

– System Key = what FreeqS treats as the source pitch
– Set Key = where you want to go
– Set to Key cents for fine targeting
– Key step and host Key + / Key –

– MIDI note-on -> Set Key (octave-relative or full MIDI range)

⸻

MotionRec (internal automation)

– Per-control and global arming: Read * Write * Clear * Power
– Capture and play back: Freq Shift, Hz readout, Custom min/max, mapping curves, Original fine splits, and Set-to-Key note
– Host transport/PPQ when available; in standalone, bar-length or custom-time internal loop while Power is on
– Import / Export FreeqS MotionRec as .more
– Parallel to host automation – ride FreeqS motion as session data, not a DAW automation replacement for every parameter

⸻

Workflow & Host

– Soft bypass with latency-matched dry (clean on/off)
– Tooltips toggle for dense gigs vs learning mode
– Settings for visibility, detect length, processing, and MIDI
– Plugin + standalone

What’s the point?

Most tools either key lock or frequency shift and expect you to juggle the math. FreeqS does both- and it also detects audio keys =)
> Detect, aim, shift – in Hz land or Pitch-ville – then MotionRec the move if you want it to repeat. Fast enough for a live set. Precise enough for a mix.
