Midiflow

The app crashes on the first note struck when a roli seaboard in single channel mode is connected to an analogue synth

Beautiful interface and very intuitive. I am using it successfully to remap my electronic drum kit for use in GarageBand on iOS.

There were a number of midi utility apps to choose from when I was looking last year and feel very happy I chose midiflow. I chose it then because it had all the features I could want (admitedly some via in app purchase) plus it seemed to be the most active (more recent releases and updates) than anything comparable. Now the same developer has just released a suite of midi utilities that are built around a specific purpose. While I like the new tools alot and think Audiobus 3 is great I am still very glad to have this app on my device not least of which is because it works on older (pre iOS 10) devices.

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.
