MidiFire is a versatile and free-form AUv3 MIDI effect host developed by Soft Audio. It serves as a CoreMIDI router, processor, monitor, and clock source, allowing users to drop and arrange MIDI ports and modules on a canvas to route and process MIDI events. Whether creating complex MIDI processing setups or keeping it simple, MidiFire offers flexibility and customization. Users can save setups as scenes, share them, and switch between them using MIDI program change messages. The app also supports Bluetooth MIDI sessions, virtual CoreMIDI ports, and is compatible with various interfaces.

MidiFire stands out with its Stream Byter module, enabling users to create custom processing modules using textual rules. Additional niche modules like Tracking Clamp and Robotic Knob enhance MIDI control capabilities. For more information, tutorials, and support, users can visit the MidiFire website.
