After months of experimenting, tweaking, designing and probably turning a few too many knobs, Abduction Protocol is now publicly available. Abduction Protocol is a free dual-instrument ambient synthesis system that runs entirely in your browser. No installation, no DAW required, and no complicated setup. Just open it, connect a MIDI keyboard if you want to play it, and start creating.
The idea behind Abduction Protocol was simple: create an instrument that makes it easy to build evolving ambient sounds, drones and melodic sequences without having to start everything from scratch.
Rather than making a single synth, I wanted to create a small system where different parts of the sound could interact with each other.
That's where Red//Relay and Ghost//Grid come in.
Two instruments, one harmonic system
Abduction Protocol consists of two connected instruments:
- Red//Relay is the drone generator.
- Ghost//Grid is an ambient sequencer that generates melodic movement around it.
Both instruments share the same global root note and scale. Set them once, and they form the harmonic framework for the entire system.
Ghost//Grid uses this information to keep its generated sequences within the selected root note and scale, while Red//Relay provides the continuous drone foundation underneath it.
This means you can experiment with changing notes, randomising sequences and creating movement without constantly worrying about whether everything is going to clash.
You choose the harmonic direction. The system takes care of the rest.
1. Red//Relay: the drone generator
Red//Relay is the constantly running part of Abduction Protocol.
It is designed specifically as a drone generator, so it doesn't wait for you to play individual notes. Once activated, Red//Relay continuously produces sound and evolves in the background.
It contains three independent voices, each with its own tuning, detuning, level, drift, motion, timbre and spatial positioning. You can choose between several basic waveforms and combine the voices to create anything from subtle drones to much more complex textures.
The voices can slowly move and drift against each other, creating variation without requiring constant interaction.
You can then shape the overall sound using the resonant low-pass filter and built-in echo effects.
There's also an Evolution Engine, which can introduce additional generative movement into the sound.
You can let it run automatically or trigger mutations yourself.
The result is an instrument that sits somewhere between a traditional synthesizer and a slowly evolving sound generator — something that can provide a continuous atmospheric foundation while you work with the rest of the system.
2. Ghost//Grid: controlled randomness
While Red//Relay provides the drone, Ghost//Grid adds melodic movement.
Ghost//Grid is a scale-locked ambient sequencer. You can choose the number of steps, tempo, octave and playback direction, then generate or modify patterns within the selected scale.
Sequences can play:
- Forward
- Reverse
- Forward and reverse
- Randomly
You can also mute individual steps or change their scale degree.
Because Ghost//Grid follows the global root note and scale, its generated sequences remain within the harmonic framework you've selected.
This makes it particularly useful for ambient music, where a little bit of randomness can create interesting movement without completely losing the musical context.
Draw your own waveform
One of the more experimental features in Ghost//Grid is the ability to create a custom waveform.
Instead of selecting only a traditional sine, triangle, saw or square wave, you can draw your own waveform directly in the browser.
It's a small feature, but it opens up another layer of sound design. Draw something subtle for a softer tone, or create something much more irregular and see how it behaves when combined with the sequencer, filter and spatial effects.
Shape the movement
Ghost//Grid also includes an amplitude envelope, resonant low-pass filter and slow filter modulation.
The modulation can be extremely slow, allowing sounds to gradually change over time rather than behaving like a traditional synthesizer.
The built-in Afterimage effects section adds delay and reverb, while the spatial controls allow you to move the sequence around the stereo field.
You can choose different panning behaviours, including alternating, sweeping, random and orbiting movement.
This makes it possible to create sequences that aren't just changing musically, but are also constantly moving through the stereo image.
Built for experimentation
Abduction Protocol isn't designed to replace your DAW or become an all-purpose synthesizer.
It's more of a musical playground.
Start with a root note and scale. Let Red//Relay establish a drone. Start Ghost//Grid. Randomise the sequence. Change the waveform. Increase the space. Let the drones drift.
Sometimes you might end up with a usable ambient patch within a few minutes.
Other times, you might just discover something strange and interesting.
That's part of the point.
MIDI keyboard support
Abduction Protocol supports MIDI keyboards for playing notes directly.
The keys of a connected MIDI keyboard can be used to interact with the instruments and play notes, giving you a more hands-on way to explore the system.
The MIDI connection is focused on note input: the knobs, sliders and other controls on your MIDI controller do not control the corresponding parameters in the browser. Those controls remain available directly in the Abduction Protocol interface.
This keeps the setup simple while still allowing you to use a physical keyboard to play and explore the sounds.
Record your ideas
Once you've found something interesting, you can use the built-in recording functionality to capture your session.
This makes Abduction Protocol useful not only for experimenting with sounds, but also for quickly capturing ambient ideas, drones and sequences before they disappear.
You can then take those recordings into your DAW and continue working on them there if you want.
Presets to get you started
If you don't feel like starting from an empty patch, Abduction Protocol also includes presets. These give you a starting point for exploring the system and understanding how the different components interact.
But the real fun starts when you begin changing things.
- Try changing only the root note.
- Then change the scale.
- Mute a few steps.
- Reverse the sequence.
- Slow everything down.
- Increase the reverb.
- Draw a completely different waveform.
Small changes can turn the entire character of a patch around.
Why make another browser synth?
There are already plenty of synthesizers, sequencers and generative music tools available. For me, the appeal of Abduction Protocol was less about creating another conventional synthesizer and more about creating a specific musical experience. I wanted something that could produce ambient material quickly, while still giving you enough control to make the result feel personal. Something you could open in a browser, connect a keyboard to, and immediately start exploring: No preset hunting for an hour, no complicated routing, no huge collection of modules.
Just a small system designed around sound, movement and harmonic experimentation.
Free and browser-based
Abduction Protocol is completely free to use.
Because it runs in the browser, you can simply open it and start experimenting. There are no plugins to install and no DAW required. If you have a MIDI keyboard, connect it and use the keys to play and explore the instruments. If you don't, you can still explore the system directly in your browser.
If you're interested in how it works, I've also created a manual that goes through the different controls and features in more detail.
But honestly, I'd recommend trying it first.
- Pick a scale.
- Start the drone.
- Start a sequence.
- Turn a few knobs.
And see where it takes you.
