Sequentia is a generative MIDI sequencer for synths, drum machines and modular. Add a module and it writes its own part: drums, basslines, arps, chords, melodies. Press Random and a full pattern is playing. Turn on Mutate and it keeps evolving while it runs. The pattern libraries are written for techno and acid, and the generative modules go further out than that. Seven finished demo tracks come with the app, to open and take apart. WHAT WRITES THE PARTS Drums, eight lanes, with the swing each genre actually has. Bass, sixteen styles from techno to dub to EBM. Acid, 303 lines that really slide. Chords and Arp, in your key, following each other. Stabs, from skank to rave. Piano, drawn by hand or written for you. Euclid, three rings at different lengths, drifting apart and landing together bars later. Rain, notes falling from a drizzle to a downpour. Bounce, physics balls playing your key off the walls. Sampler, your own loop, warped to the tempo and the key. Mod, LFOs that sweep your synth's knobs on their own. Vinyl, a record that turns while the rack plays. Mixer, to solo, mute and balance live. ONE STUDIO, YOUR WHOLE RIG Every module picks its own MIDI device and channel, so each machine gets its own part. MIDI over USB-C, Bluetooth or network. MIDI Clock keeps the gear in time. In Logic, Ableton and any other DAW the app is a MIDI source you can record straight onto a track. Leave the app and the music keeps playing, with the controls on your Lock Screen. MODULATE AND CONTROL YOUR HARDWARE Pick your machine from the library and its control map loads, ready to turn: over a hundred and thirty synths, grooveboxes and drum machines, every map read out of its own manual. Put an LFO on any of those knobs and it sweeps in time with the pattern. Arm the red R, turn a knob by hand, and the move becomes a loop locked to the bar. CC coming in works too, so a controller fires Random, Mutate, mutes and the transport. LIVE JAM Every module keeps pattern slots. Fill them as you go and switch on the bar, like clips. Live Performer is one pad for the whole rack: move a finger and every module answers at once with more density, new variations or a break. Fills, swing and humanize are a tap each, while everything runs. SCENES, AND A SET YOU CAN PLAY Save a section as a scene, put the scenes in order, and the timeline plays the set. Or switch scenes by hand while it runs. A project holds several racks, each with its own key and tempo, so a breakdown can sit lower and slower than the drop. ONE PROGRESSION, EVERYTHING FOLLOWS Write the chords once. The basslines, arps and stabs follow the changes. NO HARDWARE YET Every module plays through the app's own synth, free, so a whole track works with nothing attached. Load your own samples into the Sampler, or build a drum kit out of them. EVERYTHING IN ONE PROJECT Notes, patterns, scenes, samples, routing and arrangement live in one project that saves itself. Take the whole thing out in one step: the rack as MIDI, or every scene as its own folder, named so the session opens in your DAW making sense. Samples come with it if you want them. ON IPHONE AND IPAD One app for both. On the tablet the rack becomes a grid of cards you page through, three across on a 13 inch. Menus come in from the right and leave the instrument where it is. Open a module and it steps into the middle of the screen with its settings beside it. Landscape, for a stand and two hands. Turn iCloud on and the same projects, presets and samples are on both devices, in a Sequentia folder you can see in Files. Off until you switch it on. Sequentia is free, and so is the built in sound, Live Performer and CC Control. Sequentia Pro adds pattern slots, scenes, several racks, every drum style, your own libraries, unlimited projects and MIDI export.

But the pricing for a license to run this app is horrible. $80 to avoid paying a subscription fee? Disappointing. **Developer response:** Thanks for the kind words about the design and the sounds. Lifetime is not the only way to get Pro, and it is not needed to use the app fully. There is a monthly plan and a yearly plan, both priced to be accessible, and most people start with the monthly one. Lifetime is a separate option for anyone who does not want a recurring payment at all: bought once, never renews, yours permanently. That is why it sits above a year of the subscription rather than below it. ### 5/5 — Impressive app! *2026-09-05* An impressive new app. If you want a streamlined tool for live jamming and sequencing external gear (drum machines, synths), particularly for electronic music, you need to try this out. I was shopping for a more powerful hardware sequencer. For the time being, not anymore! One difficulty with using sequencers is that you need a good balance between usability and depth. Too technical and deep and you get stuck in programming stages and experiments. Too superficial and you end up with the same bloopy sequences or beats again and again. Here you can quickly find a key, lay down one or two types of sequences (e.g. acid line, general bass, or stabs, basic euclidian) and then randomize, create quick variants, and apply various mutations. Even better: you can work out sequences on phone (and now ipad) with stock sounds to use later once you’re back working with hardware. All of these features push you towards making music. For example, you can’t edit the stock sounds and the core sequence types are deliberately constrained (e.g. a single euclidian sequencer has three pulses at a time). I’ve used the app quite a bit in the last week and have found a couple minor bugs, usability issues, and had a couple of ideas for development. Possible bugs: Sometimes stabs pitch up and down an octave when you enter them or randomize. It’s not always clear why. The visual representation has also been inconsistent on them sometimes. I also love the new iPad release generally (was using phone version on iPad) but I’ve noticed if I add variations (which introduces a new bottom row to the rack card) the display cuts the very top and bottom off of the display. Still perfectly usable, but might benefit from being longer. Usability: I like the ‘halo’ gradient effect when you touch the screen and make selections. It works well on the dark versions of the app. However, on the light versions, the halo obscures the display enough that it can be difficult to navigate some options. Ideas for development: I much appreciate the minimal approach and like the choice to avoid too much customization. Suggestion 1: I would love to be able to offset the start of a sample (e.g. to start a bar or two into the sequence). Suggestion 2: in the chord sequence, I would appreciate the option to select ‘silence’ or ‘no chord’ for a section of the sequence. This would allow for sequences with breaks. Thanks for your work on this, keep it up! **Developer response:** Thank you so much for the high praise and for such valuable and helpful feedback. The ideas you suggested will definitely be considered for future improvements to Sequentia. And thank you as well for reporting the bugs - they will also be carefully investigated in detail. ### 4/5 — Very intriguing app, but… *2026-09-04* $80 is a little steep for the perpetual license. I completely understand that developers need to get paid, particularly solo ones, but $80 is on the extreme high end when compared to some of the best tools in the industry. I mean I can get some of the best synths, fx, sequencers out there, packed with content, for significantly less and those are backed by a team of devs and piece of mind that it won’t be vapor ware in 6 months. BTW, this does really appear to be a well thought out, polished app that’s worth investing time into learning but the pricing model as it is now is probably gonna be too much of a barrier. I’d love to be able to outright own the app, but for now I’ll probably continue testing the free portions as long as possible, to get a better feel for what’s on offer here. Kudos to the dev if there’s no time limit or major restrictions for checking it out. My advice to the dev would be: you have a legitimately interesting app here and to consider a rent-to-own option and/or dropping the full price to $30 max. Again, I sympathize with the plight of a solo developer, but some of the best iOS music making apps are a fraction of the cost of this one. I mean access to Apple Logic on iPad costs me $4.99/month. Either way I’m really interested in testing out this app and will support it the best I can if the functionality matches the presentation, but the pricing does seem a little out of sync with market. **Developer response:** Thanks for the feedback. Lifetime is not the only way to get Pro. There is a monthly plan and a yearly plan, both priced to be accessible, so everyone can pick what fits their budget. You do not need the Lifetime version to use the app fully. The monthly Pro subscription unlocks everything. ### 5/5 — so much fun *2026-09-03* Very inspiring workflow with a perfect balance between manual input and generative features (both is possible). The UI is fun both on iphone and tablet. Amazed by every single update! **Developer response:** Thank you for the great review! 🖤 We definitely plan to add a "run in background" option in the future. Due to technical constraints, an app must generate its own audio to remain active in the background. To make this possible, we are working on a major update that will introduce a full internal audio engine. This will achieve two major goals: it will officially enable background operation, and it will allow musicians to create, hear, and save ideas entirely standalone, without needing to connect external MIDI devices. Stay tuned! ### 5/5 — Masterpiece *2026-09-03* A masterpiece of software. Powerful, great looking and very well made. **Developer response:** Many thanks for your positive feedback and the high rating. ### 5/5 — Great potential *2026-08-17* Lovely app with huge potential. Curious what the developer does with this gem of an app. Keep going! 5 stars hands down **Developer response:** Thank you for your high rating and support! ### 5/5 — Game changer !! *2026-08-07* One of the most inspiring MIDI sequencers I’ve ever used. The generative workflow is intuitive, creative, and incredibly fun for live performance. A few feature requests that would make it perfect: * Add a Waldorf Protein CC preset/mapping. * Add a Song/Playlist mode to chain projects seamlessly for live sets. * Make pattern variations even faster to trigger during performance. * Please bring native iPad support! Thanks for creating such a unique and inspiring app!! **Developer response:** Thank you so much for the five stars and such thoughtful feedback, we really appreciate it. We'll definitely add a CC preset for the Waldorf in an upcoming update. And in a bigger update coming later, there will be a Scenes mode and a Live Jam mode, which will let you do exactly what you're asking for. Down the line, once the app is stable and fully featured, we'll definitely look into iPad support too. Thanks again for the support. ### 4/5 — Fun app so far *2026-08-05* This is a fun app so far, good UI, intuitive, and easy to use. However any time I add a module like, bass or acid, the extra modules do not produce any sound. Only when I mute and unmute them do they play the first step and then nothing else. **Developer response:** Thank you for your high rating and feedback! We’ll definitely investigate this bug and fix it in the next version. Thank you for reporting it and for helping us make Sequentia better! ### 5/5 — Amazing app *2026-07-27* Really fun! Love pulling my phone and just jamming around with this app. Very well thought interface for iPhone. **Developer response:** Thank you for the high rating and the positive review! I really appreciate your support. There’s a lot more exciting stuff already in development, and I’m looking forward to sharing it with you. Thanks for supporting Sequentia! ### 5/5 — 2026 *2026-07-26* Excellent! Plz Auv3, adaptive to Cubasis 3. **Developer response:** Thank you, that really means a lot, and thanks for taking the time to leave a review. AUv3 and an iPad version, so it fits nicely with hosts like Cubasis 3, are both things we want to do. Right now the focus is getting the iPhone experience fully right based on real user feedback, and AUv3 plus iPad support are next once that groundwork is in place. Thanks again for the kind words. ## Frequently asked questions about Sequentia ### What is Sequentia?

The rack is a grid of cards you page through, three across on a 13 inch. Menus arrive from the right and nothing underneath them moves. Open a module and it steps out of the rack into the middle of the room with its settings beside it, so you are looking at the thing you are changing. Landscape, for a stand and two hands. Your projects, on both Turn iCloud on and your work follows you. Start a track on the phone in the morning and open it on the tablet in the evening, with the presets, the samples and the covers already there. There is a Sequentia folder in Files, so a project is a file you can copy, send and keep like any other. Off until you switch it on. Export the whole thing at once One door for the whole project instead of one module at a time. Take the rack out as MIDI, or every scene as its own folder, named so the session opens in your DAW already making sense. If there are samples in the rack, one tick brings the audio along with it. Fixes A sample dropped into a rack that was already playing now starts on the beat instead of a sixteenth late. A modulation lane keeps the name of what it is aimed at when you close the project and open it again. ### 3.1 — 2026-08-22 Bounce A new module. Balls travel a box, and every wall they touch plays a note in your key. It looks like chaos and runs on the grid, so it grooves. Set how many are flying and how fast, hold whole fields as pattern slots, save the ones you like as presets, follow your chords, and bounce any length of it to a .mid file. New sounds Twenty eight of them, and they land where a rack usually thins out: eight pads, six keys, six basses, four modular voices, a lead, a bowed string and two more acid patches. Every one is loudness matched to the rest, so a new sound changes the character and never the volume. The app now holds 174. Scenes set up your synths A scene can send a program change the moment it starts, so the right patch is already waiting for the first note. It can send CC as well, picked straight from your instrument's own control map, and CC can fire again as the scene leaves, to put the filter back where it was. Every rack keeps its own tempo and key A rack is a section now, not just a set of parts. Give the breakdown its own tempo, put the last one in another key, and switching racks live carries both across on the bar line. A new rack starts from the one you were standing on, so nothing changes until you want it to. More machines in the CC library It nearly doubled. A hundred and thirty two instruments from twenty two makers now load their real control map, each one read out of its own manual: Roland, Korg, Sequential, Oberheim, Yamaha, Behringer, Teenage Engineering, Sonicware, Modal, Dreadbox, ASM, Strymon and more. The chart also walks you through getting a controller talking to the app, step by step. Fixes Your saved projects show up again after updating. Nothing was ever lost, the shelf just would not draw. And a shelf that cannot be read comes back on its own instead of being saved over empty. A crash that could happen while one rack played and you looked at another. Custom kit samples no longer click, and a long hit like a ride keeps ringing when the next one lands. Stabs patterns open in the editor exactly as they sound. ### 3.0 — 2026-08-17 Sequentia 3.0. The app stopped being a rack that loops and became a track you can play. Pattern slots on every module Roll a pattern you like and keep it. Roll another. Every module holds its slots, and you switch between them on the bar while everything runs. A slot hands back exactly what you put in it. Scenes A section of your track, saved. Put the scenes in order and the timeline plays them, or jump around by hand mid flight. The last bar of a scene can be a fill, and you say what happens at the end: loop, stop, or hand over to the next rack. Several racks in one project A rack is a whole set of modules. Keep up to eight of them in a project and change the rack live, on the bar, with a fill to announce it. You can build the next rack while this one is playing. Sampler Bring your own loop in. The app reads its tempo and key, warps it to the project, and it plays with everything else. Trim it, reverse it, pitch it, keep a different take in every slot, and export the warped file exactly as you hear it. Your own samples in Drums Drop your WAV one shots onto the eight lanes and the kit is yours. Tune, decay, tone and reverb on each lane, a folder used as a pool so every roll pulls a different hit, and kits you save and reuse. Your controller turns the app CC coming in moves the app's own knobs. Random, Mutate, mutes, note length, octave and the transport, all from the controller in front of you. Inside the app there is a searchable chart of every CC it answers, next to the switch that turns it on. Vinyl A record that turns while the rack plays. Nothing to program. Projects The library is a shelf of covers now, and a project has a page of its own. Shoot your own cover, rename it, play it from the shelf. A project saves itself. Undo goes back a hundred steps and survives closing the app. Seven tracks in the box Night Shift, First Light, Redline, Slow Motion, Voltage, Invaders, and Live Jam, which runs fifteen minutes in four movements. Open one and take it apart. Sound Fourteen drum kits drawn from scratch, with every hat on its own metal. A new voice for the built in synth: unison, FM, noise, drift, and velocity that opens the filter. The reverb and the delay were rebuilt so you can hear them. Also Eleven themes. An intro you can watch again. One fader for the whole drum kit. Ten more machines in the CC library. Every menu speaks the same language, and there is not one system alert left in the app. Fixed The last chord of a progression cut off at the loop. Chords disappeared after a key change. Random answered with silence. The acid drive crackled. Scrolling broke on iOS 26. ### 2.1 — 2026-08-03 Three new modules. All three are free. CC Control Your synth's own knobs, on the phone. Pick your machine from the built-in library and its real control map loads, ready to turn. Over fifty synths, grooveboxes and drum machines, every map read out of its own manual. Arm the red R, turn a knob, and that move becomes a loop in time with the rest of the rack. Live Performer One pad for the whole rack. Move your finger and every module answers at once: density, variations, a break. Your arrangement, played rather than drawn. Euclid Three rings, each at its own length. They drift apart and land together bars later, which is the whole reason euclidean sequencers exist. Also in this version Chords ships a library of real progressions. Piano writes techno melodies, and you now decide what happens to your own melody when the project key changes. Hip Hop doubled its grooves and Glitch joined the list. The menu is rebuilt, undo works everywhere, and a shake takes back the last step. Fixed A module could show one sound and play another. The performer's ride would not switch back to manual. Typing a name could stall the app. Menus could be clipped at the bottom of the screen. ### 2.0 — 2026-07-22 Sequentia 2.0. The app makes sound now. Until this release Sequentia only spoke MIDI. No gear connected meant silence. That is over. Every module has its own voice and plays straight through the phone. Press Play and you hear the pattern, no gear needed. BUILT-IN SOUND 87 sounds: 12 acid voices running a real 303-style emulation, 67 polyphonic presets, 8 drum kits. Families run from acid and bass through keys, plucks, pads, organs and kits. Open Sound in a module's menu, pick a family, pick a preset. It switches live while the pattern is playing, so you choose by ear instead of by name. Every module opens on a sound that fits what it writes, so a rack of six does not come out sounding like one instrument stacked six times. The speaker button on each module turns its sound on or off, and every preset is loudness matched, so changing sound changes the character and never the volume. Connect real gear and the phone sound steps aside. It will never double your synth. NEW MODULE: STABS Chord hits. Skank, stab, rave. 12 styles plus Random, loop length from 4 steps to 32, and a preset library. The chord slab visual shows every voice at its own pitch, so you can watch the chord move. DRUMS: 984 GROOVES, 18 GENRES Techno, House, Trance, Psy, Disco, Dub, Synthwave, Pop, Rock, Lo-fi, Funk, Hip Hop, Reggaeton, R&B, UK Garage, Trip-hop and more. Each genre carries its own swing, so House feels like House instead of Techno with different drums. PIANO WRITES IN A GENRE Not one generic style any more. Pick the genre and the phrasing follows it, so Piano sits with the rest of the rack. BACKGROUND PLAYBACK The pattern keeps running when you leave the app. Lock screen and Dynamic Island show what is playing, and a tap brings you back. ACID SLIDES ACTUALLY GLIDE They never did. The app wrote slides and the gates went legato, but the pitch never moved, on hardware or in the export. Now a slide bends pitch on your 303-style gear, in the exported MIDI, and in the built-in sound. BETTER STARTING POINTS Every styled module now lands on something usable the moment you add it, before you touch a control. Arp follows a Chords module by default. FIXES Bass Mutate did nothing on 8 of its 15 styles. It works on all 15 now. Rain drops trigger exactly the note you see hit. Onboarding and the in-app Manual were rewritten around the built-in sound. Sequentia still talks to your hardware first. The sound is there for when the hardware isn't. ## Apps similar to Sequentia | App | Rating | Price | Category | | --- | --- | --- | --- | | [Mochizuki - AUv3 Synth](https://appshunter.io/ios/app/mochizuki-auv3-synth/id6776942580) | 3.5 (10) | Free | Music | | [Derson DSynth Mobile](https://appshunter.io/ios/app/derson-dsynth-mobile/id6778253991) | — | Free | Music | | [Orbeat: Drum Machine](https://appshunter.io/ios/app/orbeat-drum-machine/id6783843640) | 5.0 (6) | Free | Music | | [MOUND - Music Generator](https://appshunter.io/ios/app/mound-music-generator/id6768479656) | 4.6 (5) | Free | Music | | [Nugget 02 - Series 9000](https://appshunter.io/ios/app/nugget-02-series-9000/id6767371080) | 5.0 (2) | Free | Music | | [Beat Kitchen Harmonic Synth](https://appshunter.io/ios/app/beat-kitchen-harmonic-synth/id6780983442) | 4.8 (12) | Free | Music | ## More apps by Yahor Kamarou - [Pleex](https://appshunter.io/ios/app/pleex/id6504772498) All apps by Yahor Kamarou: https://appshunter.io/developer/1551374720 ## Related topics [midi sequencer](https://appshunter.io/ios/topics/midi-sequencer) · [sequential](https://appshunter.io/ios/topics/sequential) · [step sequencer](https://appshunter.io/ios/topics/step-sequencer) · [beat sequencer](https://appshunter.io/ios/topics/beat-sequencer) · [synth sequencer](https://appshunter.io/ios/topics/synth-sequencer) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
