MidiFire is a free-form, modular AUv3 MIDI effect 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.

Initiate and connect Bluetooth MIDI sessions within the application.

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 mac on the Mac 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.

All I can say is AWESOME!

I’m solo guitarist/singer using Midibridge on my iPad mini 2 to interface Stage Traxx to TC Helicon Voicelive 3 through Quicco mi.1. I’ve been working on changing my setup to use Mainstage 3 to reduce the connections I have to make during setup. MidiFire is a godsend. I can still use Stage Traxx on my iPad mini 4 and connect through core midi to my MacBook Pro. The best thing I like about the Stage Traxx - MidiFire setup is that I can send a tempo value midi message from Stage Traxx to the Dynamic Clock in MidiFire, and Mainstage concert can be set up to accept the midi clock directly from MidiFire. I reverted back to my Harmony G XT and will use Stage Traxx and MidiFire to mute harmony during performance. I will also setup my FCB 1010 with the mi.1 for manual control of Stage Traxx and Mainstage. I’m always looking for ways to get more efficient in setup and breakdown. I’ll be able to reduce the time from 15 minutes to 10 minutes. Thank for a Great app at a reasonable price!

MIDIFire is an excellent app. It offers all the power of MIDIBridge and MUCH more in 64-bit (iOS 11 compatible). It has been working flawlessly for me. The Graphic user interface is beautiful, powerful, and intuitive. The ability to save my setups and easily transfer them to other iOS devices is a very welcome addition. MIDIFire should be a part of any serious MIDI user's setup. Thank you, Audeonic!

Fantastic app and service

I've been looking for a solution to my live iOS setup for a while but could not find a MIDI utility that accomplished what I wanted to do. I found the MidiFire scene setup to be easy and intuitive. And not only does the Stream Byter solution inside MidiFire solve the problem nicely, Nic at Audeonic offered amazingly swift and helpful support. Highly recommended!
