Steps by Reactable is a small yet powerful MIDI sequencer that allows you to create complex rhythmic patterns in a surprising new way. Forget piano rolls and experiment with Steps’ inspiring dials. With Steps you can control any MIDI compatible app, send MIDI over network to your laptop or any other compatible device, and even synchronize external hardware analog synths such as Korg Volcas or Pocket Operators via an audio cable. Features: - Plug and play MIDI-out system automatically sends to all available MIDI input ports and our own virtual port. - Bluetooth LE MIDI support - Audiobus 3 Support as MIDI and Audio Sender - Connect your iDevice with an external MIDI interface and control MIDI hardware. - Synchronize external hardware synths such as Korg Volca or Pocket operators via the audio output. - A carefully designed user interface that allows you to quickly switch between performance to editing mode. - Play together with Ableton Link and sync multiple apps and devices over WiFi. - Global Swing function (50% - 75%) - applied automatically to eight and sixteenth notes. - Save and recall sequences, seamlessly during playback. - Global bpm control ranging from 20 to 999 BPM. - Global Gate level allows global control of note duration. - Global MIDI velocity control. - Global Glide function applies pitch bend to small distances between adjacent steps (if the synth being controlled supports pitch bend). - Global transpose ribbon allows for easy transposition of the entire pattern. - Step pitch preview function (available while transport is stopped). ## Key features - MIDI-out system - Bluetooth LE MIDI support - Audiobus 3 support - External hardware synchronization - Performance and editing modes - Ableton Link integration - Global swing and BPM control ## Recent user reviews (10 of 18) All indexed reviews: https://appshunter.io/ios/app/steps-midi-sequencer/id1224149283/reviews.md ### 3/5 — No built in little sound *2023-02-10* Would be great for in the go music making. What a shame. All I need is a sine wave or square going through a vca. Please update ### 4/5 — Great app, just one bug *2022-06-29* I think this app is great and it will do just what I need it to which is sending some midi notes over Bluetooth midi to control a DMX lighting controller from my iPad. But I seem unable to send a midi note of C-2, no matter what I do. In my DMX controller midi note 0 corresponds to note C-2. I can send C#-2 but when I pull the octave slider all the way down and pull the note for any of the 8 steps all the way down it will note send the C-2 note. Bump them up one note and they send C#-2. I can work around that but would be nice for that to work. Thanks! ### 4/5 — Simple, Novel Sequencer *2020-02-25* The thing I wish I had known before I bought it: Steps is a single, 8-note sequencer. Each note can repeat up to 8 times, but that’s not the same thing as a 64-note sequencer. That said, it’s nice UI putting together a melodic line on a phone. The dials make an interesting, if not particularly earth-shattering, sequencer interface. Build is solid, got it working with Animoog on Audiobus in just a few minutes. ### 1/5 — NO SE OYE EN IPAD 12 pro *2019-11-27, version 1.4* Acabo de instalar STEPS en un iPad 12pro, sistema versión 12.14 y no se escucha nada. Las cinco estrellas son para SNAP que funciona perfectamente. ### 5/5 — Powerful and Intuitive *2018-11-27* This Midi Sequencer can do some pretty cool things and has a great user interface. Their other app SNAP takes this app as a basis and makes a more streamlined version of a sequencer but this can make some very experimental sounds. The compatibility to sync with TE Pocket Operators or other hardware that uses a sync track is a really neat feature too. I’m very surprised this is 100% free with no in app-purchases or adds of any kind. You would be missing out big time if you don’t at least give this or SNAP a try. Please allow STEPS to customize the color interface as you can in SNAP. I remember emailing you a long time ago asking for said color change feature in STEPS but you you’d “leave it as green for now...” and then I see the feature in SNAP so now I feel like your teasing me haha. Otherwise I think the two apps are among the best in the App Store. A great minimal approach to UX/UI design that should win an award in my opinion. **Developer response:** Wow, this is the kind of review that one hopes for when developing musical apps. We're so glad you like it and hope that you keep enjoying the many possibilities of STEPS. Stuff like this is what gets us going. If you would like to contact us (I think I replied to your email earlier) with videos or tracks of you using steps we'll be more than welcome to publish it to our followers. And if you liked STEPS maybe have a look at ROTOR. ### 2/5 — Limited *2018-08-14* Pretty limited in practice, developer doesn’t respond to email... confused why this app got rave reviews. ### 5/5 — Another Amazing Product! *2018-06-02* This with the SNAP drum app seem to represent a new direction for apps....performance! How many piano rolls does a person need? This is no piano roll or old school sequencer. How nice would it be to rework whole sequences with a swipe of finger? Intuitive to the point of a primal connection with the tactile sensation and music alterations. Love this app like all this company's app. Suggestions: MIDI channel and cc control options and maybe add another whole sequences to have like 4 pages of steps - 1 each color and control more than 1 app, chord creations, or act as an LFO with cc control. Must buy ### 2/5 — Meh *2018-05-24* Good connectivity with other apps/devices and the interface is nice. The sequencer boasts of complexity but it really isn't complex at all. No randomised ordering, polyrhythmic possibilities, multiple sequences, or measures longers than 8 notes, this is really limiting and disappointing to be honest. I expected more from a paid app. ### 2/5 — Only 8 steps...? *2018-03-24* Need more than 8 steps to create a track... ### 3/5 — Not really... *2018-02-09* Unfortunately only 8 Steps!!! At „16“ Steps and some little modifications there are full stars. ## Frequently asked questions about STEPS ### What is STEPS - MIDI Sequencer used for?

(For iOS devices this means at least iOS 8 and for Macs it means at least Yosemite) - You can transpose the octave for a greater range of playback. Easily visualize which octave you're in betwen our -3 to 3 range. - You can now visualise rests in "Target Mode". We also added a nice new way to open or close all the steps. Just drag your finger up or down the "Gate Modes" button. This lets you work even faster when changing sequences live.
