Finally someone has built an App to address the shortcomings of ep-133, ep-1320 and ep-40. These machines are beautiful and highly capable but confusing. This App brings a ton of quality of life features that make the ep series more fun.

This app breathes new life into the ko ii. I already loved it but now this app has got me beat making nonstop. I especially love the chord production feature (which has always been my weakness). This app is definitely worth it!
