Build Music Like a Modular System

dRACKS is a node-based music workstation where patterns, synths and effects connect visually to create evolving sound.

A Different Kind of Music Software

dRACKS isn't a DAW. It's a visual patching environment where every sound starts as a connection between nodes.

Pattern Generators

Euclidean rhythms, Markov chains, L-systems, step sequencers. Nodes that generate MIDI events algorithmically — not manually drawn.

Synth Engines

FM synthesis, granular, wavetable, physical modelling, 808 drums. Each synth is a node that turns MIDI into audio signal.

Effects & Modulation

Filters, reverbs, delays, vocoders. LFOs and envelopes modulate any parameter. Everything shapes movement in the system.

Visual Patching Canvas

Drag nodes, connect cables, build generative systems. Everything is visual.

Euclidean DrumSequencer Wavetable DrumSynth808 SVFilter Output LFO Audio signal MIDI events Modulation

Audio Signal

Stereo audio flows between synths, effects, and the output node.

MIDI Events

Pattern generators send note-on/off messages to trigger synth voices.

Modulation Routing

LFOs and envelopes control any parameter on any node in the system.

Designed for Generative Composition

Every pattern generator uses algorithmic processes to create evolving, non-repeating musical structures. Compose systems, not loops.

Euclidean Rhythms

Distribute pulses evenly across steps. The mathematics of rhythm.

Markov Chains

Probability-driven note sequences. Each note influences the next.

L-Systems

Fractal growth rules that generate self-similar melodic structures.

Probability Sequencing

Per-step trigger probability. Controlled randomness in every beat.

EUC SYN FLT REV MRK LFO DLY OUT GRAPH engine

Built for Performance

Real-time audio demands zero compromises. The engine is designed from the ground up for lock-free, sample-accurate processing.

JUCE Plugin Architecture

Ships as AU, VST3, and Standalone. Works inside your DAW or on its own.

Lock-Free Audio Engine

No mutexes in the audio thread. Atomic parameters ensure glitch-free real-time processing.

Topological Graph Processing

Kahn's algorithm sorts the node graph every block. Automatic cycle detection with delay insertion.

Sample-Accurate Scheduling

Event queue with sub-sample precision. Every trigger lands exactly where it should.

Host Sync & Swing Clock

Tracks DAW tempo, time signature, and transport. Adds swing and micro-timing offsets per step.

Scene Morphing System

Eight snapshot slots with cubic interpolation. Morph entire parameter states smoothly over time.

Morph Entire Systems

Capture the complete state of your rack into scene slots. Then morph between them — every parameter interpolates smoothly.

  • 8-slot scene system for parameter snapshots
  • Capture and recall complete rack states instantly
  • Cubic ease-in-out morphing between any two scenes
  • Per-parameter target tracking with smooth transitions

Common questions

What formats are included?

All plans include AU, VST3, and Standalone builds for macOS. Windows support coming soon.

What does "devices" mean?

Each license is hardware-locked. Monthly allows 2 machines (e.g. studio + laptop). Yearly allows 3.

Can I cancel anytime?

Yes. Monthly subscriptions can be cancelled at any time. You keep access until the end of your billing period.

Is there a student discount?

Get in touch at hello@lowquo.io with your student ID and we'll sort something out.

What DAWs are supported?

dRACKS works in any DAW that supports AU or VST3 — Ableton Live, Logic Pro, Reaper, Bitwig, FL Studio, Studio One, and more.

How does offline access work?

dRACKS validates your license online, then caches it locally. You can work offline for up to 72 hours before needing to reconnect.
