What's New in Sequentia

3.0

August 17, 2026

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.

Great potential

Lovely app with huge potential. Curious what the developer does with this gem of an app. Keep going! 5 stars hands down

Game changer !!

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!!

Response from developer

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.

Fun app so far

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.

Response from developer

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!

Amazing app

Really fun! Love pulling my phone and just jamming around with this app. Very well thought interface for iPhone.

Response from developer

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!

2026

Excellent! Plz Auv3, adaptive to Cubasis 3.

Response from developer

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.
