Sleep & wind-down Focus & deep work Stress & relaxation Energy & wellbeing

Choose what you want to work on tonight — sleep, focus, stress, energy. The handbook tells you exactly which frequencies to run. Sequence Pro cycles through up to 10 of them automatically while you sleep.

Runs while you sleep

Set it once — it advances on its own until morning.

Zero guesswork from night one

The 200+ frequency handbook shows exactly what to run.

Works in the dark

Rotary click-dials you adjust entirely by feel.

A signal you can verify

Pure sine wave, 24k gold-plated coil — hear it in the demo below.

How it works

Hear what sequencing does.

Sound on. One clip is a single frequency on repeat — the ceiling of every other device. The other runs a 10-frequency sequence. Same device, same speaker, fifteen seconds.

Single frequency

One tone, start to finish. Every other frequency device sounds like this.

10-frequency sequence

An evolving harmonic that shifts as the device advances through each frequency. Only Sequence Pro does this.

Same Setup. Same speaker. The only difference is sequencing.

The core idea

A single frequency is one note.
A sequence is a song.

Your body moves through states — alert, settled, deeply at rest. A single tone matches one of them, then keeps playing long after you've moved on. A sequence changes with you, each frequency handing off to the next.

01
Your state keeps moving

Alert becomes settled becomes deeply at rest. It's a path, not a switch.

02
A single tone stands still

Every other device plays one note. Right at first — then further and further from where you are.

03
A sequence moves with you

Each frequency hands off to the next, automatically — your frequencies, on Autopilot.

Prime
The first frequency settles you in

7.83Hz or 174Hz. You settle in as the program opens.

Shift
The middle frequencies carry the session

Each tone bridges to the next. Every transition is audible through a connected speaker.

Deepen
The final frequencies hold to the end

The slowest ranges run longest, and the device switches itself off on your timer.

Programs

Pick a program. Press start.

15+ ready-made programs in the Protocol Handbook, from beginner (2–3 frequencies) to advanced (7–10). Plus blank templates to design your own.

Most usedSleep Induction
6 frequencies · 30 min

Winds you down in stages, then holds the slowest, deepest range for the rest of the night.

Settles you first, then climbs step by step into the range associated with active concentration.

The system

Three parts. One nightstand.

The Device generates the signal. The Coil delivers it. The Protocol Handbook tells you exactly what to run and when.

Device

Device

Generates every frequency from 0.01Hz to 500,000Hz. Rotary click-dials, 4-channel output, dual USB-C.

Coil

Coil

Upgraded 24k gold-plated coil. Delivers a clean, stable analogue sine wave for years.

Engineering

The signal is the product.

Most frequency devices output a square wave — jagged, digital, unstable. Sequence Pro generates a pure analogue sine wave. The difference is measurable, and you can hear it.

Square wave

Most devices

Hard transitions, harmonic noise, drift under load.

Pure sine wave

Sequence Pro

Smooth continuous oscillation through the gold coil. Stable at every frequency.

0.01 Hz Full-spectrum coverage 500,000 Hz
Delta0.1 – 4 Hz

Deep sleep and physical restoration

Theta4 – 8 Hz

Meditation, calm, emotional processing

Alpha8 – 14 Hz

Calm focus, relaxation, flow states

Beta14 – 30 Hz

Active concentration, mental performance

Gamma30 – 100 Hz

The Protocol Handbook

Zero guesswork,
from night one.

Not a pamphlet — a professionally designed book covering the science, history, and practical application of every frequency this device generates.

  • Foundations of frequency science

    Physics of waves, biological resonance, brainwave states, and how cells respond to electromagnetic signals.

  • 200+ frequency library, A to Z

    Every frequency with descriptions, suggested use cases, and quick-reference charts organised by theme.

  • Ready-made programs, beginner to advanced

    Pre-built 2, 6, and 10-frequency programs for sleep, stress, focus, recovery, and meditation.

  • Custom protocol builder

    Step-by-step guide to designing your own programs, with blank planners and session logs.

  • Research references and bibliography

    Curated peer-reviewed studies with transparent sourcing throughout.

Setup

Running in three minutes.

Pick a program
1 — Pick a program

The handbook lists every program with exact settings. Beginners start with 2–3 frequencies.

Dial it in
2 — Dial it in

Push-and-rotate: L1 for whole numbers, R1 for decimals. Confirm and chain up to 10.

Set the timer. Lights out.
3 — Set the timer. Lights out.

The program runs the night and shuts itself off. Nothing else to do.

The science

Three layers. One untouched.

Most routines work on the first two. Sequence Pro was built for the third — the electrical signalling your body already runs on.

Chemistry

Supplements, vitamins, medication. Works while you take it, stops the moment you stop.

Behaviour

Apps, meditation, breathing exercises. Works with daily discipline, fades when life gets busy.

Electromagnetic

Your heart beats on electrical pulses. Your brain thinks in electrical rhythms, measured in Hz. This is the layer Sequence Pro generates frequencies for.

"Thanks a lot for this device. its switched on almost all the time. I sleep well and it feels good to have it by my side. I could track the shipping and the customer service is very fast in their response and very helpful. Overall very happy with everything."

"I bought it for me but used it with bilateral speakers instead of headphones. My husband fell asleep within two minutes. We both felt we slept better."

"I have been meditating with ketamine for about 18 months, and I have been doing it correctly. Controlled breathing, and Sofegio frequency sound and music. What I have been doing is not using headphones, putting my music on one side, and playing frequency 963 sitting on my other side. And the experience is quite amazing. I absolutely recommend this device when doing deep medication work. Do it right and ascend your consciousness :) Good luck!"

Questions

Frequently asked.

What makes Sequence Pro different from the original Harmonia?

A complete redesign: a cleaner signal through a thicker gold-plated coil, 5× the frequency range, 4 simultaneous outputs, automatic 10-frequency sequencing, rotary click-dials, dual USB-C power, and the 200+ frequency Protocol Handbook.

I'm new to this. Is it the right device to start with?

Yes. The handbook guides you from your first session with beginner programs using just 2–3 frequencies. Pick a program, dial it in, set the timer.

How does the 10-frequency sequencing work?

After setting F1, choose "Next" to set F2, up to F10. Set your global ON/OFF intervals. The device plays each frequency for the ON duration, pauses, and advances automatically.

Do the 4 output ports play different frequencies?

No — all four ports output the same active frequency simultaneously. They're for connecting a speaker, earphones, and antenna at once without splitters.

Is it safe to use every night?

Sequence Pro operates at extremely low field intensities comparable to Earth's natural magnetic field. Do not use with a pacemaker, implanted electronic device, or epilepsy. Consult your doctor if pregnant.

What's in the Complete System?

Everything in Sequence Pro, plus the Speaker, external Antenna, Carry Case, and gold-plated braided AUX cable.

Limited first run

Every night without it is
another night of the same.

Sequence Pro was designed for people who are ready to stop guessing and start using frequency with precision and intention.
