At first my opinion for was what can I do with this? I experimented and changed the circles. I found one that sounded so good. Thank you for being alive this is my favorite app.🎶🎶🎶🎶

Great app, but needs customizable layouts like it's iPad counterpart

The sound distorts quite badly through the speaker on my iPhone 6S Plus running iOS 9.1. Other sound-making apps do not do this.

really fun to use and to experiment with

The iPad app Orphion triggered my re-interest in electronic/digital music. It's fantastic to finally have an even more portable instrument to play with. My 10 month old granddaughter loves it too!

I bought Orphion for the iPad and liked it, but didn't even realize there was an iPhone version. Upon discovering it was only 99 cents, it was an easy decision to try it out. The iPhone version sounds great, and even the smaller screen wasn't a huge problem because it was nice to hold the device and use both thumbs to reach the whole screen. As a MIDI controller, the app is excellent. I don't think it does velocity control (or I didn't figure it out), which is too bad. But the feeling of controlling a powerful synth library with the clean, neat interface of this app is pretty great. Really the only problem I have with the app is the once cited multiple times by other reviewers, which is that this iPhone version does not allow you to set up your own pad arrangements. There are probably about 10 of them available, and you can transpose them up or down with the sharp/flat buttons. But that leaves a pretty limited set of options. In the iPad version, there is a 99 cent in-app purchase to edit your own pad arrangements. Perhaps the developer thought the iPhone screen was too small for that, but some type of solution is needed, or the app is just a bit too limited in its usefulness. That problem aside, I really enjoy the interface and the sound of the instrument, which is sort of like a percussive plucked string. Certainly worth 99 cents, but could be better with more control options.

I would love the option of changing keys and moving further up and down the scale easily.

This is an incredible instrument but it is limited compared to it's big brother Orphion. I really wish there was an option to edit the notes/scales, at least give us more than 9 presets. It just seems like a demo version of Orphion. Here's and idea, why not just make Orphion for the iPhone? Or just give iPhone users the option to purchase the editor, like in Orphion. Why give iPhone users a lesser version? It's just a missed opportunity for the developer to make more money and have the app reach a wider audience. As it stands now, it seems like a demo/toy and I can't really use it they way I'd like. Such a shame for what could be one of the best midi controllers on the iTunes Store.

If you aren't creative this is not for you. If you are get it cause it's completely amazing and simple and I haven't even explored the midi yet.

the sound is really nice, especially with bass tones. works great at controlling other apps that accept midi. not able to edit the layouts and scales though. as a result it's much more limited than the ipad version.
