midiSTEPs is a powerful and fun MIDI AUv3 step sequencer app that sends MIDI note and CC messages to other music apps and external synthesizers. It was designed to be super easy to use in a way that's similar to the SH-101 sequencer, where you can just quickly enter a few keyboard notes and you're ready to hit play and hear your sequence. At the same time, it also incorporates many ideas from other classic and modern sequencers, allowing you to set control values per step, mute and skip existing steps, switch between multiple patterns and parts, sync and link patterns in various ways, and modify your sequences.

midiSTEPs was designed from the ground up as a touch-based iPad sequencer app, so it's super easy and intuitive to enter, edit and play sequences.

64 step sequencer based on the classic SH-101 sequencer

The idea is great and the app has a nice, simple look. I bought it to sequence chords on my DeepMind12 and it...almost...works. It crashes after working beautifully for a few moments. I'll stick around for an update because the potential is huge. When working properly it will keep me from purchasing something like the kordbot. I'm hoping the issues get sorted out. Godspeed developers!

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.


Very, very cool app, but needs some explainer modules!

I make a lot of music on the iPad and have tons of apps all linked together through Audiobus, and with MIDI control of other apps through studiomux (app), so one could say I've got a pretty good handle on things. But for whatever reason I have had the hardest time figuring out how to make this app work and have it be fully integrated into my workflow. I've fiddled around a ton and have managed to figure out a thing or two, but it's gotten to the point where I end up wasting so much time trying to figure out how to actually get everything to work. I'd like to think its intuitive - the UI is clean and beautiful - but it's just not...for me.

This app is FOR SURE awesome, and I know if has a ton of potential that I am just not tapping into yet, but it definitely needs some walk through tool tips or an explainer video to show you how to control other apps / synths etc.

The feedback above also applies to midiLFOs. Looking forward to more tuts / explainer vids because I'd love to have this be a go-to app in my setup.
