MidiFire is a free-form, modular AUV3 MIDI FX host, CoreMIDI router, processor, monitor and clock source from the makers of MidiBridge.

Drop and arrange MIDI ports and modules onto the canvas however you like and connect them up to start routing and processing your MIDI events. Pan, zoom and scroll the canvas. Add as many ports and modules as you wish. Connect them in series or parallel. Cascade them together. Merge and split. You can create highly complex MIDI processing setups. Or keep it simple - the choice is yours.


Essential processing modules for channelising, filtering, transposing, 'monofying', remapping and monitoring - or create your own. All included with the standard app.

A highly accurate remotely controllable MIDI clock source.

Save your work into recallable/re-usable scenes. Share your scenes with other devices, computers and people. Switch between your scenes via configurable MIDI program change messages.

Download even more functionality within the app for free using the 'Scenes Club' for useful and special-purpose scenes that you can incorporate into your workflow.

Define multiple virtual CoreMIDI ports to segregate your MIDI streams.


MidiFire supports all CoreMIDI hardware interfaces, the network interface, virtual ports (self owned or other apps') and Bluetooth MIDI.

Also available for iOS on the App Store. Scene files are interchangeable between iOS and macOS.


What sets MidiFire apart is the newly extended Stream Byter module first pioneered in MidiBridge. With this you can write your own processing modules using textual rules.

Newly added constructs to the Stream Byter include: IF/THEN, local/global variables, mathematical functions, timing variables, 'onload' rules, setting of block labels and sending arbitrary MIDI data. The Stream Byter is backwards compatible with rulesets you already have from MidiBridge; just copy/paste them in.


Also included are some specialised modules:

• Tracking Clamp - reduce tracking miss-hits from MIDI guitars.

• Robotic Knob - generate complementary CC messages to control synths and FX based on your playing.

• OSC Exchange - send and receive OSC data across a MIDI channel (DIN, USB, wifi or Bluetooth) between MidiFire instances.

Super-solid, super-flexible MIDI router/toolkit!

Wow! A MIDI routing app that never crashes, that lets you take your MIDI from one place and reliably (as in 100% of the time) route it to another…With a super-pro user interface, and a responsive developer, to boot! This app rocks, and it has become a vital part of my setup. I’ve purchased this app both for my MacBook pro as well as my iPad—it’s THAT good, and it’s become THAT ESSENTIAL to my setup. Bravo!

Must-have for MIDI musicians

This is the app that makes my hybrid DAW and MIDI hardware setup work painlessly. It's a mega-powerful MIDI patchbay in software, and if you're using USB MiDI for your device connections it provides all the functionality (and then some) of the classic hardware-based MIDI processing boxes for a fraction of the cost. Here's hoping an Apple Silicon version is on the horizon.

Super-deep yet easy to use!

Love this app. I use it to convert MIDI Note velocities into MIDI CC’s that I can then use to control FX etc. Makes FX super-expressive. It’s amazing.
