United StatesMidiflow 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.
Where is the return button!!!
I bought this app with high hopes and it can do the simplest thing which is to go back to the previous page….??!!! Do not waste your money I want a f..ing refund!!!
United StatesThis app looks abandoned, and for me, buggy
I want to be nice because I know these i-apps are not big money makers for smaller developers. Midiflow has (imo) a fantastic feature set, and once you get to know how it’s organized, it’s pretty easy and quick to set up a patch for very detailed and complicated scenarios. I bought the app, then paid for all the IAPs. I should have checked here and on his forum first. Johannes seems to have abandoned this program. When it works, it’s great, but it’s unstable. It crashes a lot, right after I edit a song. I save the song (overwrite), switch to another song, crash - and when I go back to the song I was editing, all the edits I made before saving it are gone! Make the edits again, save (overwrite), then save an extra copy (with a different name) as a backup. Switch songs, crash. Once again my edits are gone, AND the backup song I saved is gone too! To say this is extremely frustrating is an understatement! I know this isn’t the place for bug reports but as someone else mentioned, Johannes’s forum is locked and the most recent post there is over a year old as of this writing. I got an automated response to an email I tried sending to the admin of his forum saying “we don’t respond to emails, ask on the forum”, lol. The last update to this program is a year ago. All this to say I’m disappointed that I can’t recommend this app, as great as the features are. I play music for a living and was hoping to take this and my iPad on stage with me. I’m honestly not sure what I’m gonna do. Things do seem to be working when I’m not trying to save songs, and I already have many hours invested learning the app and programming the presets for the gig I’m doing. More stress testing I guess, once I have the programming finished. I probably shouldn’t update my iPad’s OS now, no telling what will happen!
United StatesUseful, but no support
Good set of features for managing your MIDI chain on IOS, but if you run into a bug or have a question there is no response, and the community forum is locked
United Statesiphone version can’t use
IOS14 iPhone11, no back to main button, can’t return parent menu, such as edit name, change velocity…
United StatesForce closes when I try to remap
Sad that I paid for the app annnnd the remapping function Please fix as this is really the only reason I bought this
United StatesPricing too complicated, does not work with AUM
The title says it all. You get the app then you have to start buying all the bits and pieces individually, and you really don't know which ones you need because info is very cryptic written for engineers not musicians. Additionally it does not work inside AUM.... or at least I did not find a way of making it show. A true pity because it should be a very useful app..... Great idea, poor implementation. It happens frequently when you fall in love with coding and do not listen or check your software with the end users.
United StatesExcellent MIDI router for iOS
Midiflow is a focused, full-featured, and efficient app for routing MIDI data among devices connected to an iOS tablet/phone. It is intuitive to setup, and basically worked straight away. The fact that it runs in the background is a crucial feature for any MIDI routing app. Setup and use case is this: Three MIDI-capable devices on a USB hub connected to my iPad Pro via the camera connection kit. Devices include: a digital mixer, a programmable MIDI foot switch, and a DMX lighting controller that has 5-pin (DIN) MIDI In port connected to the USB hub via a USB<->DIN MIDI controller cable. A multitrack audio app sends digital audio to the mixer and midi note instructions to DMX controller. MIDI foot switch needs to send MIDI note and CC commands to the audio app, digital mixer, and DMX lighting controller. As is, only the audio app properly receives and sends MIDI data, since it is acting as a MIDI host app the iOS device; but, the app does provide MIDI thru/router functions to forward the MIDI data to other destination devices. Enter, Midiflow. Midiflow is setup to receive MIDI data from the foot switch and forward these commands also to the mixer and DMX controller devices. Works perfectly! This is a rather simple use case, but good demonstration of Midiflow’s critical function. Add to this its ability to also transform MIDI data while routing it to the proper destinations, while running as a background app on iOS... Just perfect!
