Midiflow

Please implement using joystick controllers.

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.

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!!!

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!

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

IOS14 iPhone11, no back to main button, can’t return parent menu, such as edit name, change velocity…

Sad that I paid for the app annnnd the remapping function Please fix as this is really the only reason I bought this

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.

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!

When I try to search for nearby devices, the app closes. I bought for two iPads in case one of them was wrong. The app does not work on none of them.
