A VST3 bridge for audio plug-ins

GrandBridge — the Universal Bridge Between Your DAW and the Full Power of Your Computer

GrandBridge loads in your DAW as a standard VST3 plug-in. Open any FX or instrument inside it, and the intelligent scheduler distributes its workload across CPU cores. As a result, any plug-in — old or new — becomes part of a true multicore system. GrandBridge bypasses a major bottleneck shared by all DAWs: uneven core utilization, where one core is already overloaded while others remain idle.

Result: suitable projects with several heavy plug-ins can gain up to 4×–16× more practical headroom. Actual gains depend on the DAW, buffer size, plug-ins and project structure.

How GrandBridge Distributes the Workload

Your DAW project

Available CPU cores

GrandBridge distributes the workload

FX and instruments

The DAW passes selected plug-in processing to GrandBridge. GrandBridge distributes that work across available CPU cores while latency, automation and project recall continue to behave as expected.

A Complete Plug-in Workflow

Workload Distribution Across CPU Cores

GrandBridge distributes the work of multiple plug-ins across available CPU cores.

Native-Style VST3 Shells

Create a dedicated VST3 Shell for any hosted plug-in.

Host & Global MIDI Control

Map hardware MIDI CC controls to GrandBridge Auto slots or Macros.

Macros & Automation

Expose hosted parameters to the DAW and group several controls behind one Macro.

GPU Zoom for Plug-in GUIs

Scale plug-in interfaces that were never designed for modern displays.

Sandbox Isolation for Every Plug-in

Each hosted plug-in runs separately from the DAW and the other plug-ins.

Built for Real Projects

FX and instruments, modern and legacy formats, direct GrandBridge hosting or dedicated VST3 Shells.

The largest CPU gains appear when a project contains several heavy, independently processable plug-in instances.

  • VST3 plug-in
  • VST3-compatible DAWs
  • Demo available
  • Host / Global MIDI Learn
  • Automation Slots
  • Dry/Wet for any FX
  • Macros: multiple parameters on one knob
