Around 2000-ish I was making music with a similar piece of software called Jeskola Buzz which is also a modular[1] tracker[2].

About 5 years ago I remember thinking it would be cool if I could use that type of UI again and it would be great if something like that existed that could run on my tablet. So I searched and I was amazed when I found SunVox. It's a very capable piece of software, highly recommended

So much love and respect for SunVox, watch this unbelievably beautiful example song with crazy surprise about halfway through: https://youtu.be/AHFSrxlouh8

Immediately reminded me of Jeskola Buzz [0]. While most screenshots don't show it, it also had a tracker included [1].

One of the very few softsynths that has good interface for touchscreens, think it is the only one I have found that I actually enjoy using. Not a big fan of its sound, just not what I am after, but I don't mind it and it works great as a portable scratchpad.

I've been using SunVox on and off for like 15 years now. I'm not really musically inclined, but I always come back to toy around for a bit. The creator is the sort of mad genius type, he seems to have made his own programming language and cross-platform rendering toolkit to make it all work and has a number of projects based on it. Because of this, SunVox is available on basically any platform you can think, including both major mobile OSes app stores and Linux for a few dollars ($5, iirc) and is definitely worth it. If you're familiar with a sequencer workflow (other notable projects: LSDJ [^0]), it doesn't seem too "out there", though the built-in synthesizers tend to lean towards a more airey feel. Highly recommend loading up the example projects, lots of people (including the creator) have some samples in there to poke around with. It's really interesting seeing how different people use the tools provided to compose, sometimes taking wildly different approaches to get similar results.

TLDR: download it and load up the sample projects, it's really fun

Ah, SunVox. It's like an instrument that Alexander Zolotov (AKA NightRadio) made for his own (excellent) music, and has generously shared with the world, creating a virtuous cycle of refinement in both his music and the instrument.

I can't say enough nice things about SunVox. When I first saw it I was looking for trackers, and didn't spend much time with it. The second time I was looking for modular synthesizer apps, and that's when I fell in love. SunVox was my "gateway drug" to deeper learning about audio synthesis and processing techniques.

You can create entire compositions and useful effects processors with SunVox using only the modular synthesis parts of it. It's very tracker-oriented, and you can do lots of tracker things with it, but don't be fooled into thinking it's a tracker. It HAS a tracker, and that is a strong part of its history and common usage, but it is much more than that. The modular interface is very approachable and powerful once you get accustomed to some of the fundamentals.

"MetaModules" are one of its secret weapons. They let you package an entire SunVox project into a module, and expose an interface of up to 96 controllers, along with audio and note I/O. They can be arbitrarily nested… MetaModules all the way down. Besides sharing full compositions, MetaModules are one of the primary ways people share their creativity in the SunVox community. One prolific producer just released a collection of 236 modules built over the last four years. [1]

Heck, it's even Turing-complete. Someone implemented a CPU using SunVox! [2]

SunVox has a library version that lets you embed the audio engine into your own app [3] and there's even a WASM version. It's particularly well-suited for games, because you can control up to 16 independent SunVox instances at a time (to separate music and SFX for example) and it will mix them together.

During my own explorations of SunVox I reverse-engineered and documented the file format [4] and wrote a library called "Radiant Voices" [5] for Python and TypeScript that lets you read and write SunVox files. If you read/write to specific filesystem locations, you can effectively hook into the SunVox clipboard, making it possible to write auxiliary apps that smoothly integrate with SunVox.

One of my favorite experiments combining those techniques was to create a "MetaModule Construction Kit", which lets you use Python to create and manipulate MetaModules parametrically, experiment with them using MIDI and an alternative UI, then copy them over to SunVox itself once you are happy with the resulting MetaModule. [6]

(Sadly, I don't find myself having enough time as of late to keep those side projects up-to-date with the latest versions of SunVox. YMMV if you decide to explore them. Contact me if you want to chat about them at all, especially if anyone's interested in collaborating to help bring them back in sync with the latest version of SunVox.)

I could go on and on singing praises about this software (and other apps created by the same author), but I'll spare both the reader and myself… for now. :-)

For the adventurous, a new beta was released earlier this month:

https://warmplace.ru/forum/viewtopic.php?t=7005

For the iOS version: $6, no subscription, no tracking?

Bought it before even looking at all the screenshots, if for no other reason than supporting developers like this.

I used his PhonoPaper software to do this... https://youtu.be/HT0HH_fc4ZU

This is a great sounding synthesizer; but closed-source as it seems; the compiled shared libraries can be downloaded and I found an old version of the source code here: https://github.com/bohwaz/sunvox.

Best example of a work done with this software imho

I used it in a few game jams and can thoroughly recommend it.

The interface might be intimidating at first, but with two wave generators and a couple of patterns you can already conjure a passable background track. A bit more complexity and it can sound pretty good.

Wow can't believe this ran on a Palm. I wish I had known this back in ~2005

Check out https://www.bespokesynth.com/ as well and it is completely open source

I was impressed by how fast it launched when I tried it.

man that's so frickin' beautiful

I always thought this software was weird. To me modular implies parameter modulation for sound design, but this seems to be designed around sequencing fixed sounds, or am I missing something?
