Charis Cat shared this in-depth look at creating the After Eight Step sequencer – a DIY project that extends traditional step sequencing with artificial intelligence.
The After Eight Step is an Arduino and Max-powered 8-step sequencer. It uses Markov Chains to generate musical accompaniment, based on any sequence of notes. Details on this are available on Cat’s site.
If you’re interested in creating an After Eight Step sequencer, source for the project is available on github.
