Audulus 4: iOS and macOS modular synth is now FREE, iPhone support, and ditches subscriptions - December 11,2025

Audulus 4, the multi-touch iOS and macOS modular Synthesizer, is now FREE of charge and the latest update adds iPhone support and ditches subscriptions

Audulus is one of the longest-running modular Synthesizer apps on iOS, including macOS support. Taylor Holliday, the developer, has just released update 4.7, making the synth free of charge. You read it right.

The latest update 4.7 gives you the whole Audulus 4 experience for free (down from $19,99) with plenty of modules to explore. He also discontinues the subscription option.

Instead, you can expand Audulus by purchasing the Pro series modules via in-app purchase. They start at $1,99. You don’t have to, though, as the synth is fully usable for free. But if you want to support the developer, you can do this.

The update also introduces a new Lua message protocol for richer, faster vector graphics. Furthermore, it now includes an iPhone version.
This is excellent news! Now everyone with an iPad, iPhone, or macOS can use Audulus 4 without restrictions. Happy patching!
