唯一的功能全面midi路由转换软件

非常好用. very good. 希望作者能开发出AUv3插件版. i hope there is an AUv3 version.

Let down by poor support

The software appears to be comprehensive, with few other apps working on iOS 15 filling this need. Although the standalone app is a disingenuous description, its not complete and requires further payment for other key aspects.
Unfortunately trying to get support on how to use it is impossible. There’s no acknowledgment of requests for help by email. Signing up to the forum does not allow requests to be made and there are a significant number of very good questions completely ignored on the forum.
Get it if you know what you’re doing otherwise look elsewhere.

Não funciona!!!

Porque a loja fica mantendo esse aplicativo ativo se ele não funciona mais. Comprei essa semana, gastei R$ 40 e não funciona. Favor devolver o dinheiro investido.

Frequent crashes

Good features, but the app crashed several times while editing the CC map, and some of the mapped CCs are dropped during performance, making it overall unreliable for live usage.

Rip off

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

Nem abre

Diz que é compatível com iOS 8 mas no iOS 10 sequer abre. 40 pratas gastas para nada.

Great app, but no support

I would have given this app five stars, but downrated it because there appears to be no support: impossible to register for the support forum, and the most recent posting there is 2021. I wanted to post a solution to a long-unanswered forum request.

Layout issues on my iPhone, can’t do what I want either

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.

App não abre

App simplesmente parou de funcionar. Abre por 2 segundos e fecha.

Antes disso, comprei a funcionalidade do remap e não funcionou.

What's up with the forum?

Great to see this app is being maintained but the forum appears to be dead - I've registered succesfully and can log in, but cannot post. The most recent post there is around 2 1/2 years old at the time I type this! I love this software but it's a bit disconcerting to think there is no support at all. I only wanted to post one minor feature request.

Between this, StreamByter and AUM, I can make an iPad/iPhone music rig that rivals what I've been doing for years on my Mac with Plogue Bidule. I'm afraid to update iOS because I might lose Midiflow!

[Addendum - 7/9/2024] - OK, since there's no way to reach the dev I can see, this wlll have to do. A user on a keyboard forum I frequent just downloaded this and immediately found a bug which I could reproduce: in the "Velocity remapping" page, select the fourth curve, then tap "Reset curve" - the box goes blank. There is no way to recover that screen I found. Next, bug or feature? Looks like Midiflow does not pass release velocity. All note-offs have a vel value = 0 coming out a Midiflow channel regardless of the actual value going in.

I still like and use this app, but seeing a locked support forum with the newest post being three years old does not inspire confidence!

Note off velocities are ignored

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.

Simply didn’t load at all after paid updates installed

I ve paid for three control updates for midi. After that, the app simply dont start (some kind of bug).
Cash in the trash.

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!!!

This 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!

Amazing but can be better

I love this app but to be perfect, it could have a way to mass sharing songs.

Useful, 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

iphone version can’t use

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

Force 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
