Most modulators hand you a shape — a sine wave, a random curve, an envelope — and ask you to map it to something. Jellygon throws that playbook out entirely. Instead of a static waveform, it gives you a spring physics simulation: a network of interconnected points that push, pull, bounce, and react to one another in real time. The result is modulation that doesn’t just move — it behaves.
Created by MUDJAQ, Jellygon is an 8-mapping modulator built around a spring physics engine. Each of the eight points in the system acts as a modulation source, and each one is physically connected to the others. Nudge one, and the ripple spreads. Apply a pulse, and the whole system lurches into motion. Adjust the mass on a single point and watch how the entire network recalibrates. This isn’t modulation you program — it’s modulation you set in motion and then ride.
The Vibe
Jellygon sits beautifully at the intersection of organic movement and controlled chaos. For producers working in ambient, experimental, or generative music, it opens up a world of slowly evolving textures that never quite repeat — the kind of subtle, breathing modulation that makes a synth pad feel like it’s actually alive. Push the spring stiffness up, dial in a heavier mass, and suddenly you’re in territory that feels like a system on the verge of collapse: perfect for industrial textures, noise-driven techno, or glitchy, unpredictable sound design.
The performance dimension is where Jellygon really sets itself apart. Because you can apply force in real time using the Grab and Pulse controls, this isn’t just a set-and-forget modulator — it’s a performance instrument. Grab a handle, pull it across the XY space, and release it; the spring system reacts, overshoots, oscillates, and gradually settles (or doesn’t, if that’s your intention). Pulse it at a set speed for rhythmic, percussive modulation bursts. It’s the kind of interaction that makes you want to record a live take rather than draw automation.
Key Features
- Spring physics simulation: A genuine physics engine drives all modulation — interconnected points that react to one another rather than running independently
- 8 mappable modulation sources: Each point in the simulation can be mapped to any automatable parameter in Ableton Live, giving you up to 8 simultaneous modulation targets
- Spring Rate control: Adjust the stiffness of the spring to define how quickly and sharply the system responds — from slow, elastic drift to tight, snappy reaction
- Damp control: Set the damping duration to determine how long motion continues after a force is applied — from quick, controlled decay to long, sustained oscillation
- Individual mass settings: Each handle has its own mass value, allowing non-uniform, complex physical behaviour across the network of points
- Handle XY / Grab: Directly manipulate individual points in 2D space — intuitive, hands-on control for live performance and sound design exploration
- Handle Attack: Shape how each point responds when force is initially applied, adding an additional layer of expressiveness to the system
- Pulse & Pulse Speed: Trigger a burst of force at a defined speed — ideal for generating rhythmic or periodic modulation patterns without manual interaction
- Parameter Range & Range Type: Precisely control the minimum and maximum values each modulation source can reach, and define the type of range mapping applied
- Wild tendency: A deliberate instability baked into the system — push Jellygon far enough and it will run wild, generating intense, unpredictable modulation events
How It Works
At its core, Jellygon places eight points into a simulated physical space where each one has mass, is connected via spring forces, and is subject to damping. When you apply force to any point — either by grabbing and dragging it via the Handle XY interface, or by triggering a Pulse — the spring connections transmit that energy across the network. Heavier points move more slowly and carry more inertia; lighter ones snap back quickly. Tighter springs create sharper, more responsive movement; looser springs produce slow, wandering drift.
Each point’s position in this simulated space is read as a modulation value and mapped directly to a parameter of your choosing inside Ableton Live. As the system moves, those mapped parameters move with it — filter cutoffs sweep, reverb sizes expand and contract, pitch drifts, gain shifts. And because the physics engine is continuous and interconnected, no two moments are ever quite the same. Even a system that appears to have settled will occasionally be nudged by residual energy into a new cycle of movement.
The combination of Grab, Pulse, Spring Rate, Damp, and mass settings means you have genuine creative control over the character of the modulation — from predictable, musical wobble through to full-on chaotic behaviour — without ever drawing a single automation lane.
Who Is It For?
Jellygon is made for producers who are bored of predictable modulation. If you’ve ever wanted your synths to breathe without using an LFO, your effects to drift without drawing automation, or your live performance to feel genuinely reactive and unscripted — this is the tool. It’s equally at home in ambient and experimental production, in live techno or industrial sets where unpredictability is a feature, and in sound design contexts where you need movement that feels human and physical rather than mathematically perfect. Map it to anything: filter cutoff, reverb send, delay feedback, pitch, volume, pan — the spring doesn’t care. It just moves.
