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.

Your state keeps moving

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

A single tone stands still

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

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

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

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

Coil

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

Protocol Handbook

200+ documented frequencies, 15+ ready-made programs, templates to build your own.

Optional

Speaker · Antenna · Case

Hear the sequence, extend the field, take it anywhere. Included in the Complete System.

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.

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.

1 — Pick a program

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

2 — Dial it in

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

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.

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.

Since I started with the Bexxly harmonia I have slept better than I have slept in years

Since I started with the Bexxly harmonia I have slept better than I have slept in years.
We put on one hertz every night to sleep and my husband and I feel like we could not live without it.
I’ve used it in my massage therapy, practice, and one woman who has beenin for in for four treatments for an hour and a half each since I put the Buckley harmonia in my clinic room, reported that she previously had continuous appetite. She was never full. She would just eat until she vomited because she had no control of her eating.
She says now she eats a regular meal she feels full and stops eating. She also feels like her gut is working better and that she’s much more peaceful and able to manage lifeand and all of it. Stress is much better.
When she has been in for treatments, I have used frequency 10 Hz, and 80 Hz.
I am so grateful to the man who created this. I don’t know where the heck I would be without it..
much gratitude, Annette

We’re truly grateful for your kind words and for sharing such a detailed experience. It’s wonderful to hear how consistently you’ve been using the device and the positive changes you’ve noticed for both sleep and overall wellbeing. Stories like yours inspire us to keep improving and supporting our community. Thank you for being part of the journey.

So far, Really Good!

So far, Really Good! I'm familiar with the technology--the clinical version of this machine helped save my leg from a staph. infection in bone. I love that this is so portable! Love the booklet of programable frequencies.

Very nice component! Nicely designed and assembled

Very nice component! Nicely designed and assembled. Buttons are thoughtful and so on. A+. Thank you!

Can’t seem to get it to do multiple

Can’t seem to get it to do multiple frequencies

Thank you for the note, Craig, and apologies for the confusion. The Sequence Pro runs up to ten frequencies one after another, each for the time you set, rather than all at once. That’s the difference between it and the single-frequency Harmonia: the device moves through the program on its own instead of staying on one tone. If you’d like help loading a sequence, support@bexxly.com will walk you through it in one reply. And if simultaneous output is what you actually need, tell us and we’ll help you find the right setup for that.
