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. midiSTEPs features: 64 step sequencer based on the classic SH-101 sequencer Set note, chord or rest per step Set accent and tie per step Set CC, velocity, length parameters per step Mute and skip individual steps Probability options for individual steps Set start and end points within sequence Edit individual steps Transpose, loop or one shot, start and pattern sync options Four independent sequencer parts with 16 patterns each per set Parts can have different speeds, lengths, sync and trigger options Pattern Mix page with clip-launcher style pattern triggering External MIDI clock sync with clock shift adjustments and swing MIDI AUv3 extension support allows you to use midiSTEPs as a plugin in AudioBus, AUM, Cubase, etc Ableton Link syncing support Audiobus 3 MIDI support Easy to set up CoreMIDI configuration and MIDI mapping Easy to use touch interface designed specifically for iPad ## Key features - 64-step sequencer - Note, chord, and rest per step - CC, velocity, and length per step - Step muting and skipping - Probability options per step - Multiple patterns and parts - External MIDI clock sync ## Recent user reviews (10 of 31) All indexed reviews: https://appshunter.io/ios/app/midisteps/id1001532047/reviews.md ### 5/5 — Very good *2023-12-29, version 3.0.5* why did I discover this before,,,,finally a tool that does the job and is exactly what I wanted thank you ### 5/5 — Love this. *2022-11-07, version 3.0.5* 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. ### 5/5 — Perfect SH-101 Sequencer *2021-03-13, version 3.0.4* 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. ### 5/5 — Creative developer *2020-12-13, version 3.0.3* 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. ### 5/5 — Thx for the update *2020-09-12, version 3.0.0* Long time user thx for bringing auv3! Lovely sequencer! ### 5/5 — AUv3! YES!! *2020-09-09, version 3.0.0* Thank you! ### 5/5 — Definitely NOT a “toy”! *2020-09-09, version 3.0.0* 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. Updating as of 9/8/2020: latest update allows MidiSTEPs to be used within AU host apps like AUM; this works very well; each instance of MidiSTEPs is one sequencer like the ones in the stand-alone app, and you can use as many as you like... ### 5/5 — Finally it's AUv3 *2020-09-07, version 3.0.0* Just became 6 stars. Incredible must have app for making music. Thanks to tge dev for doing the work so I can use it in AUM. I was using is to pump midi into AUM but now it's even more convenient and fun. ### 5/5 — MidiSTEPs *2020-09-07, version 3.0.0* My favourite sequencer now upgraded to AUV3, Yesss! Thank you Art for this app. I agree with a previous reviewer though, this is definitely not a “toy” sequencer ### 5/5 — Absolutely superb *2020-08-27, version 2.2.0* Simple and beautifully easy. ## Frequently asked questions about midiSTEPs ### What does midiSTEPs do? midiSTEPs is a MIDI AUv3 step sequencer that allows you to send MIDI note and CC messages to other music applications or external synthesizers.
