MIDI Fabric

MIDI Fabric integrates MIDI routing, filtering, remapping, real-time effects, virtual MIDI devices, and message monitoring. It helps manage complex MIDI flows in live, production, and validation environments.

MIDI Fabric routing screen

Built for complex MIDI flows

MIDI routing

Connect MIDI sources to destinations flexibly.

Virtual MIDI devices

Create virtual sources and destinations to organize inter-app MIDI connections.

Filters and remapping

Filter by channel, message type, note range, velocity, and CC number, then apply channel conversion or transpose.

Real-time MIDI effects

Process Delay, Echo, Arpeggiator, Chord, Humanize, Quantize, Gate, Stutter, and more on routes.

Scriptable effects

Define your own MIDI effects in a simple DSL alongside the 10 built-in ones — shareable, ready to drop into any project.

MIDI monitor & debugger

Inspect received and routed MIDI messages for debugging and validation.

Also includes

  • SysEx Librarian
  • MIDI Recorder
  • SMF Player
  • Clock Analyzer
  • MTC Generator
  • MMC Controller
  • Latency Tester
  • Program / Bank Change sender
  • Remote control

MIDI Fabric routing canvas

Visual MIDI routing

Lay out your MIDI graph the way you think about it. Drag sources and destinations together, branch flows, and keep complex setups readable at a glance.

MIDI Fabric route with filter, remap, and effect presets

Filter, remap, effects

Apply channel and message-type filters, transpose, velocity curves, and real-time effects (Delay, Echo, Arpeggiator, Chord, Humanize, Quantize, Gate, Stutter, …) directly on a route. Save combinations as presets and reuse them across projects.

MIDI Fabric customizable effect UI

Customizable effect UI

Each effect ships with its own UI — but its visual style and control layout can be reshaped to fit your workflow. Re-arrange controls, swap themes, or build an entirely different panel for the same processing without touching the underlying logic.

MIDI Fabric monitor screen

Real-time monitoring

Watch every Note, CC, SysEx, and Clock message as it flows through your routes. Confirm filters, verify mappings, and isolate problems without leaving the app.

MIDI Fabric MIDI debugger

MIDI debugger

A focused workspace for stepping through traffic, sending crafted test messages, probing connected gear, and tracking down protocol issues — separate from the realtime monitor when you need a deeper look. When a Device Definition is registered for the target gear, CC and other parameter names auto-complete to that device's vocabulary.

MIDI Fabric DSL effect editor

Effects beyond presets

Need a transform that doesn't ship in the box? Express it in a small DSL — channel-specific routing, conditional CC mapping, custom note logic. Your effect compiles natively and runs alongside the built-ins, so you can blend "Delay → Humanize → my-custom-thing" without leaving the editor. The DSL is declarative and travels with your projects.

Planned platforms

  • macOS
  • Windows
  • iPad
  • Android tablet
