VoidRack Pro is a playable browser modular synth built around patch cables, rack modules, and hands-on experimentation.

Build your own signal chains with oscillators, FM operators, sequencers, clocks, VCAs, envelopes, filters, reverb, delay, logic, random voltage tools, sample-and-hold, resonators, mixers, scopes, and more. Each rack row becomes a space for designing instruments, rhythms, drones, pulses, and strange generative systems.

This is not a preset machine. It is a patching environment designed for exploration.

Create simple voices or sprawling modular structures:

  • patch clocks into sequencers
  • route CV into pitch, filter, and amplitude
  • use random and logic modules to generate evolving patterns
  • blend audio paths with mixers, delay, blur, and reverb
  • shape motion with LFOs, envelopes, attenuverters, and utilities

VoidRack Pro is designed to feel like a compact experimental modular lab inside the browser, with a retro-futuristic rack interface and immediate visual feedback. It’s a tool for sound design, happy accidents, and building machines that surprise you.

Whether you want pulsing sequences, unstable textures, ambient drift, or rhythmic modular experiments, VoidRack Pro gives you a system to patch and play.

Brief instructions

Click BOOT SYSTEM to start.

Add modules to a rack row, then click sockets to patch them together. In general:

  • audio flows from sound modules into effects, filters, VCAs, mixers, then Master Out
  • gate/clock signals trigger sequencers, envelopes, and rhythmic events
  • CV modulates pitch, cutoff, level, and other parameters

A simple first patch:

  1. Add Pulse
  2. Add R-Sequencer
  3. Add VCO
  4. Add VCA
  5. Add ADSR
  6. Add Master Out

Then patch:

  • Pulse to R-Sequencer CLK
  • R-Sequencer OUT to VCO Pitch
  • R-Sequencer GATE to ADSR Gate
  • VCO OUT to VCA IN
  • ADSR OUT to VCA CV
  • VCA OUT to Master IN

Now adjust knobs and expand the patch with filters, effects, mixers, LFOs, logic, and random modules.
