Love this.

Such a great app for structuring harmonic thoughts, but I also made a killer Gene Krupa style swing groove with this using some of the length and velocity randomness features which I'll never forget.

Only request is to bring it to the iPhone, at least as an AUv3, so I can have compatibility with Cubasis projects I share/send between the devices.

Perfect SH-101 Sequencer

It’s like having 4+ Roland SH-101 sequencers on steroids. Everything you love about the 101 sequencer PLUS everything you ever wanted from the 101 sequencer in one tidy little app. And then some. Full on love affair.

Creative developer

Midisteps is a brilliant step sequencer.

used to control your sh-101 sequencer via clock in with the tr-808 trigger out? You can do that with midisteps as well. there are four sequencers, and one sequencer can control another.

Thank you for releasing an auv3 version.

Please release more applications Mr. Kerns.
