[ Jordan Rudess about this app ]
Sunvox is a serious music application. I am personally running it on my iphone. In the overcrowded world of music apps, Sunvox stands out as both unique and powerful. If you are a musician and own an iphone, you owe it to yourself to try this amazing application!

* Distortion: new type "saturation" (adding odd harmonics) + five of its variations;
* MultiSynth: new option "Output port number = random" (three different algorithms are available);
* Loop: new controller "Length unit" (line/128;line;line/2;line/3;tick;ms;Hz);
* Loop: new controller "Maximum buffer size" (in seconds) to protect against allocating too much memory;
* Loop: the maximum of the "Repeat" controller has been increased to 128 (128 = repeat endlessly);

The Swiss knives of… knives, if knives were music applications

There are a very select group of audio apps that I install on every new device before any other apps. SunVox is definitely one of those apps!

Tracker functionality isn’t everybody’s cup of tea, but the modular wiring and multitude of modules are really the star of the show. You can create just about any type of Synth and fx combo you can think of in a very lightweight environment.

I’ve been a big fan of SunVox for a long time. Many apps have come along since I first tried SunVox. Most have been relegated to being reinstalled once in a while, only to be uninstalled to clear out clutter. SunVox never leaves my devices, and it gets used very often for sound design and generative audio.

Abandoned Shell ,

Had it since the original iPad. Still love it!

This was the first music production app I got on my original ipad like 12 years ago and I still use it from time to time today! It’s incredibly robust and filled with features and if you have a little imagination, you can figure out how to create all kinds of sounds with this thing. I imagine it would be a Helpful way to learn about modular synthesis and trackers. One of my long running all time favorite mobile music production apps and I am still amazed that it was created by a single guy (much like NanoStudio). Cubasis was created by one of the industry’s biggest players and it still feels so clunky and unusable to me…. Anyway, definitely get this, you won’t regret it!

SunVox is amazing!!

Yes this app won’t cost you much money, it’s free on Mac, PC, Linux and even Raspberry Pi if you really want to try before buying. I was trying to make a stand alone box running it on Raspberry Pi but then I realized it works so much better on my Phone and this was 3 years ago. It can do so much and continues to get developed to be even better year after year. Some people don’t care for Trackers well I don’t either and I don’t use it often. I has infinite possibilities for sound creation. Works flawlessly on everything from my old 2011 iPad 2 running the latest SunVox version to my new 2017 iPad Pro.

I’m just resending my same review as before because the iOS review system is stupid!
