Get to know Hydra.

Everything you need in a modern studio patchbay, engineered for zero-latency workflows on macOS.

Process Capture

Continuous app capture with Flux.

Flux lets you tap the audio output of any application and route it anywhere — hardware outputs, broadcast streams, or VST3 effect chains — continuously, without changing your macOS system output device.

  • macOS Core Audio Process Taps (14.4+)
  • Per-app volume trim & stereo ganging
  • Continuous non-destructive background routing
  • Zero aggregate device requirement

Crash Isolation

Sandboxed VST3 hosting.

Host third-party VST3 plugins in dedicated isolated worker processes. A failing plugin will never interrupt your main audio engine, live broadcast, or recording session.

  • Out-of-process plugin host architecture
  • Automatic crash recovery & reload
  • Zero main thread interruption guarantee
  • Compatible with all signed VST3 plugins

IP Network Audio

Broadcast your audio via IP.

Full support for AES67 AoIP and NDI® network streams. Ensure perfect timing across your facility with integrated Precision Time Protocol (PTP v2 IEEE 1588) clock synchronization and SAP discovery.

  • AES67 AoIP transmit & receive
  • NDI® stream integration
  • PTP v2 IEEE 1588 clock sync
  • SAP service discovery
