Sunvox: Modular Music In Your Pocket
Sunvox is a small and highly efficient modular synthesizer and pattern-based sequencer designed to be used on portable devices. I first encountered it on the Pocket C.H.I.P., but as the mages on their website will testify, it runs on all kinds of PDAs and portable devices. It has a very impressive set of features and is free on most systems, except the Android and iOS.

Here are the specs:
- Highly optimized synth algorithms, flexible architecture; SunVox works on a variety of devices with different CPUs;
- Supported systems – Windows (2000+); macOS (10.9+); Linux (x86, x86_64, ARM (Raspberry Pi, PocketCHIP, N900, etc.), ARM64 (PINE64, etc.)); iOS (9.0+);, Android (4.1+); Windows CE (including Pocket PC and Windows Mobile; ARM only);
- supported sound systems: ASIO, DirectSound, MME, ALSA, OSS, JACK, Audiobus, IAA;
- SunVox as a plugin: AU instrument/effect for iOS;
- Support of 16/24/32bit WAV, AIFF and XI samples;

- XM (FastTracker) and MOD (ProTracker, OctaMED) import;
- Real-time sample recording;
- Real-time recording of any types of sound events (notes, Touch Theremin, controllers);
- Powerful microtonal (ultra-chromatic) sequencer;
- Generative music features: random selection of notes, random values of controllers, probability effects; see examples;
- Free cross-platform library for developers is available; so it’s possible to use SunVox engine in your own applications;
- A lot of built-in modules (synths and effects) + ability to make very complex connections between them.
This is quite a comprehensive list for such a small piece of software! More info and resources at the Sunvox website: https://warmplace.ru/soft/sunvox/
