Midiflow allows you to send MIDI from app to app in a similar way to what you already do with audio. That way, you can sync apps with each other or send MIDI parts from a sequencer app to different synth apps. You can also route the MIDI from your keyboard to apps and assign different key zones to them. Different settings can be stored as a preset, recalled later and inserted into another preset. Furthermore, all MIDI transfer can be monitored in order to find problems or just to learn what MIDI is doing (normally) behind the scenes.
Important news: There is a full documentation on the Midiflow website now!
HOW DOES IT WORK?
Midiflow allows you to create multiple routings. Each routing receives MIDI data on its source and sends it to its destination. The selectable sources and destinations include your CoreMIDI compatible MIDI interface and other apps if they provide a virtual MIDI port. You can also create custom ports that can be used by other apps to receive data from Midiflow or send data to it. A routing also has a modifier which allows you to filter data or modify it. That way, you can transpose notes, limit them to a key range, change the MIDI channel of the incoming data, etc. (see the feature list below).
LIST OF FEATURES
+ MIDI clock – specify tempo and your apps will be in sync
+ Channel filtering and remapping
+ Velocity filtering – a routing is only active for notes in a given velocity range
+ Note shift – shift all notes by a given number of half-tone steps
+ Note remapping – shift each note individually
+ Velocity remapping – apply a velocity curve, transform to fixed velocity, or specify the map value by value. In the latter case, you can also export the mapping to the clipboard, edit it in another app like Apple Numbers, and paste it back in Midiflow
+ Filtering out Clock or dividing the tempo into subdivisions
+ Filtering out SysEx
+ Connect to other iPads/iPhones via Bluetooth MIDI (iOS8 or higher)
+ Save a configuration as a preset, which can be recalled later or inserted into another preset
+ Custom virtual MIDI ports, which can be selected in other apps as a source or destination
+ Control aspects of Midiflow via MIDI. For example, select presets or control the clock with any MIDI command
+ Launch your synth apps from Midiflow (works with an increasing number of apps)
+ Sharing your configurations
ADDITIONAL FEATURES (available as an In-app purchase)
+ Filtering and remapping of controllers – transform (a) the controller type, e.g. from CC1 to pitch-bend or note value to CC1, and (b) transform the value in several ways: as a linear remapping from an input range to an output range, as a curve, or as a value by value list. In the latter case, you can also export the mapping to the clipboard, edit it in another app like Apple Numbers, and paste it back in Midiflow. This allows you to create very sophisticated remappings.
+ Controller conditions – adjust your routings depending on other MIDI messages. This allows you to create sophisticated behavior within your setup by switching routings on and off.
DOES MIDIFLOW WORK WITH MY SYNTH APPS?
Midiflow works with every app that has a correct MIDI implementation. In the best case, it has an own virtual MIDI port and can be configured so that it receives MIDI only on that port. Unfortunately, some apps don't have that, but can at least be restricted to one MIDI channel. In that case, you can send to that channel on the global MIDI port "Network Session 1". If you can't select a channel either, then the app won't work with Midiflow. There is a tutorial video on www.midiflow.com that explains this in more detail.

This app seems to do what I wanted which is to get a clock in from a usb midi interface and then re-route the clock, through the same usb interface and a powered usb hub, to multiple synths. However I’m having some difficulties with the user interface where I’m not able to return to the main page from the “create a song” page and from the “select input keyboard” page. Please fix this issue or explain me how to do it. Give 3 stars for now….
Accessing my PUC+
I just bought the PUC+, iRig Keys I/O 49, and BeatBuddy along with forScore
This app provides quick, reliable communication to all.
Thank you
Solid
There are other similar apps that are theoretically cool but full of bugs. Midiflow works without those bugs and has tons of control. So I go with the one that does it all and is solid. Midiflow to the rescue. Since there are so many features, it takes a bit of time to catch on. It took me an hour or so to get the main stuff and the rest came as I needed them.
Great app. The developer also created a bunch of must have apps to greatly enhance the new midi features in audiobus 3.
If you are into using midi in your music then this app belongs in your toolbox.
I must say that it bugs me a lot when reviewers give a bad review when they do not get the results they expected or if an app does not do what they think it should do. I suggest contacting the developer before writing a bad review in case it’s your lack of knowledge of midi that is causing your heartaches and not the app. I am able to do most things that is not possible without an app like this and kudos for how it has never shown me any bugs. I think it is the best app of its type available for IOS. How anyone can give a bad review is beyond me. Studying the details of how midi works in depth is important before trying to do advanced stuff. If you do not really understand midi in IOS and in general, trial and error will get you in trouble more and more as your setup gets more involved. And how can you blame the app for issues with ios? It bugs me because this is clearly the best app of its kind for IOS. Work with the developer instead of letting out your frustration in a review. Isnt the goal to end up with the best app possible or is it to show how smart you are by trying to blame an app for your lack of ability and you ingenuity. A bad review will not help you so why write one. Ok, if you try to contact the developer and he/she does nothing to help then go ahead, but first make sure its the app at fault.
Easy to use
I love this app, after a 30 minutes of playing with it, I realize how easy and flexible it was. Do not forget to open your apps if you want midiflow to see them.
Some deficiencies limit its usefulness
This app looks really good, with thorough documentation (yay!), but it's got some bugs and quirks that limit its usefulness, at least for my purposes.
It is not as transparent as I would like...even when you ask it to bypass any modifications to the incoming data stream, it still messes with it...blocking some Midi codes (aftertouch) and morphing some others (note off events).
One feature I really wanted was to be able to remap virtually any Midi message based on its hex code. Although it claims to be able to do this (needs IAP) it doesn't work properly at all. Instead of remapping (replacing) a code, it merely adds the new code to the data stream without replacing the original code (which is what remapping is supposed to mean).
I hope these deficiencies can eventually be remedied, but for now, I am not able to use this app for the purposes I intended.
Easy routing, powerhouse
I love this app, it's perfect. I can't wait to see if there are any other possible routing conditions that can be created, but this always works for what I need.
Solved My MIDI Keyboard Issues
I've wasted a lot of time trying to get Modstep and Animoog to play nicely with my MIDI keyboard. No matter what configure I tried, I would get stuck notes ringing forever.
MidiFlow has solved all these problems.
I now route my MIDI keyboard -> MidiFlow -> Modstep -> Animoog, and it all works perfect.
Nice clean user interface too.
Must have for Mobile MIDI musicians!
Great work, keep it up! The applications for this are pretty endless. MIDI support is quite ubiquitous for many of the commercial synths and sequencers on the app store, making this compatible with every single music app I use. If you use various MIDI controllers with the ipad like me, this is a must have for the studio or live performances. The controller re-mapping on the ipad is a dream come true for me! Thanks!!
Beware, midi on ios is super flakey
I had very little success using this app. My intention was to use it with other apps. According to the developer and other users this is largely because apps all implement midi differently and there is no real standard on iOS. Some apps works great with it and others not at all. This app may do what you want perfectly or not.
Brilliant
Great little app, exactly what I needed. I needed to split what came out my keyboard so I could record instruments on different tracks. This worked perfectly. Just ordered a drum pad with four pads, that only outputs on one channel, but I'll be able to split and route by note using midiflow. Well done.
