What's New in Sequentia

2.0

July 22, 2026

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.

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!

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.

With 2.0: the perfect companion!

Incredible with midi and now standalone !!!

Response from developer

Thank you very much for your high rating and your review. Your feedback helps us continue improving the app, and we’re glad you enjoyed the new audio engine in Sequentia.

Well made!

Very well thought out it’s so fun and functional. SUGGESTION - it’d be awesome, If you included a few more straightforward style choices like pop/rock. Kinda all techno heavy styles currently.

Response from developer

Thank you so much for the kind words and the five stars! And great point, the styles do lean techno-heavy right now. Good news: pop, rock and a bunch of other non-techno styles are already built and on the way in an upcoming update. Thanks again for the feedback, it's exactly the kind of thing that shapes what we add next.

Delightfully simple, super inspiring

I bought a lifetime license minutes after using the app with OP-XY. Ridiculously easy to set up and super fun to use as an idea starter. It’s a great way to explore genres you’re not familiar with.

I also appreciate the design of the app. The visual design and UX are on point.

$40 for a lifetime unlock is an incredible value. So stoked I found this app.

Response from developer

Thank you so much, this genuinely made our day! So glad it clicked with your OP-XY right away, that's exactly the kind of workflow it was built for. Really appreciate you noticing the design and UX work too, a lot of care went into keeping it simple. Welcome aboard, and thanks for going Lifetime!
