One of the most powerful music creation tools for iOS: modular synth (+AU), MIDI sequencer and tracker.

SunVox is one of the most powerful music creation tools for iOS. It is a small and fast cross-platform modular synthesizer with pattern based sequencer (tracker).

[ Key features ]
• Modular interface.
• Powerful microtonal sequencer.
• Highly optimized synth algorithms.
• Support of 16/24/32bit WAV, AIFF and XI samples.
• XM (FastTracker) and MOD (ProTracker, OctaMED) import.
• Multitrack WAV export.
• MIDI import/export.
• Mic/Line recording (using the Sampler).
• Audio Unit Extension (AUv3 instrument/effect), Audiobus.
• Generative music features: random selection of notes, random values of controllers, probability effects.
• It's possible to use SunVox engine in your own applications using the free library for developers.
• It is also available for other systems (see the site).

[ Brief instruction ]
The main menu - button with the SunVox icon in the upper left corner of the screen.
To connect one module (source) to another (destination): first touch on the source, second touch on the destination.

[ 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!

What’s New

Version 2.0e

2.0e: bug fixes.
* iOS 11+: SunVox Audio Unit (AUv3) can now send MIDI notes and MIDI CC to other AU modules;
* iOS 13.4+: full USB/Bluetooth keyboard support (like on desktops);
* multiple module selection + ability to save several selected modules to a sunvox file;
* timeline: supertracks (see simple_examples/supertracks.sunvox);
* improved import of old tracker formats (XM and MOD);
* new module - FMX: 5-operator Frequency Modulation synth;
* new module - FFT frequency transformator;
* timeline menu: new option "Vertical mode";
* timeline menu: new functions "Load" and "Save" to load/save selected patterns from/to a sunvox file;
* timeline menu: new function "Detach" to convert the clones to the normal patterns;
* module editor menu: new function "Detach" to detach the selected modules from the rest;
* module editor menu: new function "Make MetaModule" for packing the selected modules into a single MetaModule;
* now it is possible to delete modules, but keep the links;
* pattern properties: X and Y fields - exact coordinates of the pattern on the timeline;
* module properties: X and Y fields - exact coordinates of the module;
* module visualizer: "Phase Sync" oscilloscope option has been added; activate it to see a single waveform cycle;
* module visualizer: new buttons "reset", "apply", "copy", "paste";
* ADSR->Sustain: new value "Repeat" (repeat the envelope until the module is stopped);
* ADSR->Smooth Transitions: new value "volume change" (the volume will change smoothly, but the envelope start is not smoothed);
* Amplifier: new controller "Bipolar DC Offset";
* Analog Generator: the "Freq2" controller has been ranamed to "Osc2" (pitch deviation of the additional oscillator);
* Analog Generator: new controller "Osc2 volume" - additional oscillator volume;
* Analog Generator: new controller "Osc2 mode" - mixing mode of the additional oscillator with the main one (add;sub;mul;min;max;bitwise AND;bitwise XOR);
* Analog Generator: new controller "Osc2 phase" - starting phase of the additional oscillator;
* Analog Generator: new option "Increased frequency computation accuracy";
* Delay: new controller "Delay multiplier";
* Delay: new "Delay unit" values: sec/44100, sec/48000, sample;
* Delay: max delay length has been increased to 60 sec;
* Delay: new controller "Feedback" (for sound and events);
* Echo: new controller "Right channel offset" (how much to shift the right channel relative to the left in time);
* Echo: new controller "Filter";
* Echo: new controller "Filter frequency";
* Filter Pro: new modes "stereo + smoothing" and "mono + smoothing" for additional parameter smoothing;
* Filter Pro: new types "LP 6dB" and "HP 6dB";
* LFO: new controller "Sine quality";
* MetaModule->Play patterns: new values "on (repeat, endless)" and "on (no repeat, endless)";
* MetaModule: number of user defined controllers has been increased to 96;
* MetaModule: controller color can now be changed by adding "@X" to the beginning of the name, where X is the group number from 0 to F;
* MultiSynth: new option "Output port number = round-robin (cyclic)";
* Sampler: new option "Increased frequency computation accuracy";
* new pattern effects (column EE):
* 1A - fine velocity slide up/down (XX - up speed; YY - down speed); once at the beginning of a line;
* 33 - slot sync (for sv_sync_resume() in SunVox library);
* 34 - set (XX) or reset (YY) project options: 1 - no portamento on the first tick; 2 - no velocity slide on the first tick; (for compatibility with old tracker formats);
* 3C - copy track XX from from the pattern YY; for example, if XXYY = 0023, then the first track will be copied from the pattern named "23";
* 3D - write a random value to track YY; min value, max value and column must be in track 0, starting from line XX; see example "pat effect 3D random value";
* new examples and modules.

I don’t know how people dislike this! This app lets you be creative. It does take some time to learn and to get a used to but once you’ve got a basic understanding, you’ll be set to make some decent songs! Stick with because everything will become second nature and soon enough you will be a master at SunVox! Please get this if you’re interested in music creation as it’s absolutely amazing and the best money I’ve spent on an app. Good luck with your songs!

Too arcane for me ...

& Nov 2020 update looks interesting but I’ve no clue as to what any of it means..(I’ve had this app for years, too..)

Demos sound good, I suppose...(when I can figure out how to load them. The ui is perplex..)

Some say it’s “retro” as if that’s a good thing. No, it isn’t..research indicates this was a desktop port from time ago, fine, but touching any of the screen elements either leave me stumped or feeling like i broke something..

Apparently an external keyboard is required because the “on-screen input is fiddly”. Fail! A half decent app allows me to stick to the iPad only if I want/need to.

Others say “go find yutuub tutorials”, no, I should be able to at least figure something out for myself.

I found blip interactive apps good in this regard..

(Nanostudio 1 & 2, which is well regarded by experts for having both accessibility AND depth (no mean feat) which I’ve found to be true)..

Or else it’s “well, this apps got steep learning curve but stick with it for rewards!”, no, I have no time for numerous learning curves, how many more learning curves are required, really..can’t I just get on with making music, for once?..

Wait, what’s this. Auv3 as an effect in other daws, just added, interesting, let’s try ... and ... nope. No sound, no effects, no nothing. Still none the wiser...

Unbelievably Incredible!

I Have NEVER In My Whole Life Seen Such An Unlimited Creative Explosion of a DAW Music Studio That Not Even Is It EXACTLY THE SAME Software Port of the PC Version... BUT Has LITERALLY NO LIMITATIONS On what you want to do in any software on a pc... ON IOS!! Compared to other iOS Music Production Studios (flstudio mobile etc) This has and lets you do so much more that even a single wav sample size is literally unlimited to the point of the capability of your device. Just Unbelievably Amazing! Excellent Software!
