### 5/5 — The best

*2019-06-30, version 1.4.2*

Very deep and very configurable app. Better and more flexible than an arpeggiator I could find in a synth. For those who make music or perform live with iOS apps

### 5/5 — Great app

*2018-09-15, version 1.4.2*

Only seems to work as a midi controller, which is fine with me, I love midi controllers, as long as there are enough synths, and there certainly are enough synths available for ios, maybe too many. Just kidding, there are never enough. Arpist is great but it seems to be forgotten in the fog of the ios rush of app production. I hope the developers make sure it keeps working going forward with all the IOS operating system updates. Arpist is so much fun. Yes, fun is all that matters, isn't it. Who complains when they are having Fun? Only crazy people. Nothing against crazy people, just saying.

### 5/5 — Very cool app

*2018-01-17*

Beautiful design, nice features. Thanks!

### 4/5 — MelomethodicalPatternizationalogic!™

*2017-02-05*

A universal app that is a great iPhone Arpeggiator for single thumb programming. The iPad version is exactly the same scaled up and oriented for portrait use. Overall, it's a useful melody sketch sequencer that one can chain up to eight patterns of various lengths so you can keep it simple or make a complex melody. Each pattern can be set separately to a number of pattern types available e.g. As Played, Up/Down, Inward/Outward, Low Pedaltone Descending, Douple, Octuple, Follow Octave, Random, etc. Tempo relies on itself as a source using standard Midi Clock or can track timing from other sources. While MIDI as a timing source is good and reliable with no strange timing artifacts, it could use Alberton LINK so I wouldn't have to use another app like MIDI Link Sync.

### 5/5 — Awesome

*2015-12-08*

One of the most versatile arpeggiators on iOS.  Maybe the best on iPhone (as most are for iPad). Great UI as well. And can you believe it all the advanced features have gone free now!  If you have MIDI synthesizers you got to have this.

### 5/5 — Great arpeggiator!

*2015-12-03*

Note to music novices-this is not supposed to make sound. You use it to connect to a DAW or hardware synth that may not have an arpeggiator feature. Also a no brainer for a free one with this many features.

### 4/5 — Understanding dawns

*2015-10-29, version 1.4*

For anyone who can't get a sound from this, it's because the app is purely a controller, without its own voices. Just load up a midi compatible synth, point this app at it, and bingo! Once I understood that, the app is actually quite innovative and fun. Possibly even useful to sonic dabblers, making IOS music. Okay, there's no AudioBus compatibility, but if you're controlling an app that is compatible, no problem. Using this method we can also record into a second or third app via AudioBus.

### 1/5 — crashing - IOS9.0.2

*2015-10-13, version 1.3*

For me - and another iPhone 4s with 9.0.2 IOS, it’s currently crashing (works on first try after download - then crashes). I’ve tried soft and hard reset - still same. Re-synced phone and downloaded via iTunes on sync - still crashing… :(

### 3/5 — Probably great but crashes every time

*2015-09-22*

I'm excited to use this app at some point. The controls look like a lot of fun to use with some iOS synths or other stuff via MIDI. It doesn't get past the opening screen. Nothing responds. Just crashes after freezing for a few seconds right after it opens.

### 5/5 — My one stop go to...

*2015-05-29*

One of my favorite midi arpeggiators. I find myself using it almost exclusively... Wonderfully easy to noodle on.
