Audulus, the modular audio platform for iOS, iPad, and macOS, has announced that its full core platform is now available for free.
Audulus builds on the long tradition of visual, node-based programming. It started as an experiment in iPad-based music creation and has grown into a powerful modular environment for advanced sound design.
Users can now access the complete Audulus node library to design custom synthesizers, sequencers, effects, controllers, and advanced DSP- and graphics-driven tools. Audulus can be used to create synthesizers, sequencers, audio effects and more.
A growing set of Pro Modules is also available for purchase, offering expanded capabilities and supporting continued development of the platform.
Features:
- Complete modular synthesis environment with visual node-based patching
- Full node library for synthesis, sequencing, effects, and DSP
- Canvas Node with Lua programming for custom user interfaces
- GLSL Shader node for advanced graphics and visual effects
- AUv3 plugin support for integration with DAWs

This is vastly underrated. People seem to like the skeuomorphic interface approach, which Audulus doesn’t do, so I wonder if that’s limited adoption.
