MidiBridge is the comprehensive MIDI tool that iOS is missing and absolutely essential for anyone using MIDI with an iDevice.

A backgroundable virtual MIDI patchbay/router/manipulator that interconnects all MIDI interfaces (external, virtual and network) on an iOS device at a fraction of the cost of equivalent hardware.

- Connect any MIDI in to any MIDI out (including merge and clone)
- Add full CoreMIDI compatibility to Synthstation 25 and Midi Mobilizer I
- Go wireless between any iDevice or connect to Mac or PC
- Interconnect just about any CoreMIDI virtual app
- Apply keyboard splits, velocity curves and other useful MIDI functions on any MIDI port

- All CoreMIDI physical devices
- Akai Synthstation 25
- Line6 Midi Mobilizer I
- CoreMIDI network (as a session originator or receiver to/from Mac or PC)
- CoreMIDI virtual ports (to/from other apps)

- Runs in background
- Visual indication of connections, MIDI events received/sent/blocked and CoreMIDI network
- Full OMAC music app fast-switch support
- Support for H-Pi microtonal keyboards, including U-PLEX via USB
- Block/allow event filtering by type (Note/Program/Controller/Sysex/Aftertouch/TimeSong) and MIDI channel
- Initiates CoreMIDI network connections from iDevice
- Save/recall module presets
- Keeps track of MIDI interfaces and restores connections/modules automatically
- Streamlined efficient code passes/filters events very quickly

- Velocity curve
- Keyboard range split
- Note remap
- Note transpose
- Velocity split
- Channel remap
- Controller remap

- Drive most CoreMIDI apps (eg. Animoog, GarageBand, SampleTank, BeatMaker) from a Synthstation 25 or original Midi Mobilizer
- Connect Geo synth to SampleTank (see Jordan Rudess on youtube)
- Filter out active sense messages from instruments
- With a powered hub and Apple CCK, connect multiple USB class compliant MIDI devices and route between them
- Connect your battery operated keyboard/drum controller (or SynthStation) to your iDevice and connect wirelessly to perform cable-free
- Connect a MIDI transport surface wirelessly to your computer and move around your studio controlling your DAW transport
- Duplicate MIDI events from one external device to another and to a remote MIDI destination wirelessly at the same time
- Use as an inline MIDI filter, cloner, merger or splitter
- Connect apps that have CoreMIDI network support but no virtual MIDI support to virtual ports by connecting to 'localhost' to create a loopback virtual interface (see our website)

Indispensable in a modern MIDI environment


The developers of MIDIBridge really went all out when they created this very powerful MIDI tool. I have a rig that has evolved into a controller routing labyrinth and for sure the control data for my Eventide H9's would not find it's way with midi over USB without the power of MIDIBridge! In building a rig you might not find all of the uses at first but in the quest to get deep musical control over the modern processors and instruments that are available you will need the power of MIDIBridge. Thanks!

Great App, Great Developer


This has been my "MIDI-Ox for IOS". It's a very deep, highly configurable swiss army knife for coreMIDI. The feature set is rich and well thought out. The doumentation, website, etc, are a model the rest of the ios app industry should take note of. In stark contrast to 90% of the other apps I own (and I own a lot), the dev, Nic, has been enormously responsive and supportive of his apps. Wish he made everything. Support this guy.

Essential MIDI app. IOS 9 crashes though


This app has quickly made its way onto my list of gear essentials due to its incredibly useful and dynamic MIDI routing options, but since upgrading to iOS 9 I crash on startup. Just reinstalled as per the instructions for iOS 9 users to do so, but to no avail. I'm sure the dev will get it sorted out as quickly as possible. In the meantime, I feel slightly crippled.
