Stepp is a music sequencing plugin that provides you with a foundation for building your own audio step sequencers. Stepp offers sample accurate playback of your audio clips through a programmable sequence and a system for managing your audio files called sound banks. The result is a plugin that allows you to build any step sequencer interface you wish, and use Stepp to handle the underlying audio sequencing.

Stepp is the audio sequencing technology behind the mobile game, Lily, and this is perhaps the clearest example of the level of freedom you have with Stepp.

Stepp comes with two demo scenes showcasing music sequencers built with Stepp, including audio samples, which can be seen in the video. Additionally, all source code is included so you’re free to inspect how any feature is implemented.
