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.}

Ich habe keine Funktion entdecken können, auch nicht mit kostenpflichtigem add-on. Besitze ein iPad Air von 2025.

Se supone que trabaja desde IOS 9 y también en el iPhone 6Plus. Pues tengo mi iPhone 6 Plus con IOS 12 que antes trabajaba perfecto con midiflow y ahora ya no funciona ya la reinstale varias veces y CRASH ! No puedo ni entrar. Quiero escribirle al desarrollador pero no hay forma de comunicarse

Does not work as advertised and support appears to be non-existent.

Does not work for me anymore. After upgrading to iPadOS 18.1 it’s broken for me; it either does not launch at all or it completely loses connection to AUM and all hardware. I’m going to look elsewhere for an alternative…

The bugs I mentioned in an earlier review were resolved with an iOS update - I forget which one, it’s been a while. Midiflow has been stable for a while now, and I’ve been using it without incident. As I said then, the feature set and power this app has is great. I couldn’t do what I do without it. One perplexing omission I just discovered is its seeming inability to handle note-off velocities! As far as I can tell, they’re all turned into note-ons with vel=0. I’m OK with this although it sent me on a wild goose chase of troubleshooting that wasted a lot of time. If anyone uses note-off velocities as a modulation source for anything, you may want to look elsewhere - unless Johannes addresses this with an update. He is still unreachable, as far as I can tell. The forum is dead - and the “feedback” button on the top left of the UI (described in the documentation) is gone! It almost seems he doesn’t want to be bothered! Speaking only for myself - the app is working fine (for now) and I’m gonna stick with it as long as it works on my iPad and iPhone. I can’t help feeling a little nervous about the lack of support.

Realmente estoy fascinado con esta app, me es de mucha utilidad, el que diga que no, es porque no a encontrado todas sus maravillosas opciones, antes usaba AUM, pero en Midiflow he encontrado funciones realmente muy buenas, y hace poco traté de usar AUM con Midiflow y me di con la sorpresa que si funcionan juntas y he ampliado las prestaciones entre las dos apps, felicitar al desarrollador por su gran trabajo y solo pedirle que habilite guardar sesiones en varias instancias, para llamar una sola sesión si poner todas para no consumir recursos, espero haberme hecho entender, gracias Midiflow. Le doy 10 estrellas si pudiera.

I found a number of bugs, posted them on the support forum and got no response. Main one is layout issues in iOS 16.5.1 on iPhone 11, no ‘Done’ button/link visible so you get stuck whenever you go into a menu. On an older iPhone these navigation links appear. This app is probably good for some things, but the functionality I need (filter out Note Off messages) is not there. I was able to create this with MidiPipe on MacOS in about 2 minutes.

I was excited When I Read the I could send MIDI to several apps. But I was disappointed cause It does not work with Korg Module and VB3m organ. Works though With bs-16i. Any chance of refund?

Ich verwende Midiflow am iPad Pro, um zB die Velocity-Werte, die vom Arturia Keystep kommen - aus unerfindlichem Grund sind die praktisch immer viel zu heftig - zu korrigieren. Mit der Velocity-Re-Mapping-Funktion ist das hier ein Kinderspiel! Schlicht und übersichtlich gestaltet, dabei ziemlich selbsterklärend: ein cooles Swiss-Knife für alle Midianer*innen! Ganz ehrlich: ich finde Midiflow besser gemacht, als die allseits gut bekannte - und ein bisschen zu viel gehupfte - Mitbewerber-App, die das auch kann :-) … darum gerne: 5 Sterne!
