midiSTEPs is a powerful and fun MIDI 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

Definitely NOT a “toy”!

I have had this app for a few days, and I just can not leave it alone! The title calls it a toy, but it doesn’t feel or behave like one. I have some minor issues with it, but mostly I really like it.

There are lots of possibilities here, especially working with a multi-timbral synth like the Korg iM1 or the bs-16i. It’s extremely flexible, with lots of options for variability. I especially love the ability to randomize the notes, or the velocity, or the note gate length. Being able to do this allows the sequences to sound a lot less mechanical and boring.

The one feature I’m still getting used to is the file saving system; it just doesn’t operate the way you think it does. There’s no option to just save the “set” you’re working on, or at least I can’t find it.

It would also be really nice to have a good assortment of scales to pick from; the app provides only major & minor.

Nevertheless I still give it 5 stars; VERY interesting app.

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!

Awesome step sequencer!

This is the best sequencer out there. I use it everyday in my music creation. It has an easy to use interface and has many many features. Love it!
