What's New in Sequincer

2.1.0

October 27, 2026

New in 2.1: • Track settings: hold a track to set its volume, mute or solo it, rename, duplicate or reorder it, or move its notes to another track. • Instrument icons: every instrument and drum sound has its own. • Version History: each song keeps its earlier versions. Restore any of them as a new song; the song itself never changes. • Duplicate songs. Tap ••• on a song in the song list for Duplicate, Version History, Song Settings, Move and Delete. • You can now delete the song that's open: your most recently edited song opens instead. • Safer saving: your latest edits are saved at once when you leave the app, dynamics changes are always saved, and with iCloud, Undo no longer brings back a bar changed on another device. • A bigger free plan: 2 tracks (one can be drums), and songs play up to 256 beats. • iPhone Duo: a Mix deck in laptop pose, with a fader per track. • Fixes: quick pinches no longer send the piano roll to another part of the song, and the plan screen shows the plan you just bought. The contact form works again. If you sent a message recently and got no reply, please send it again. In case you missed it, Sequincer 2: editing, rebuilt. • New gestures: tap a note to open its settings, double tap to delete it. Hold a note's end to resize it, its middle to move it. • Note settings: velocity, tuning in cents (Composer), start, length, sharps and flats, and track, for one note or a whole selection. • Edit and Select tools replace the old modes. Tap the bar numbers to select bars. • One action bar for selected notes, selected bars and Transpose. Transposing can now be undone. • A new track panel: tools, tracks, instruments, mute and routing in one place. New to Sequincer, or coming back? An interactive tutorial walks you through it in a few minutes, in the app and in the AUv3 plugin. Made for iPhone Duo: half fold it like a laptop, with the piano roll on top and your tracks or a trackpad below. The outer screen works too. Also: the grid uses the full screen height, a clearer bar header, and fixes for the grid jumping after zooming during playback on iOS 27, Copy to next bar pasting twice, and tiny invisible notes that blocked editing.

User reviews

Hi! I am an Sequincer user.

What if our community had a Discord place?

Response from developer

Hi, and thanks for the 4 stars! A community space is a great idea. I'm looking at ways to share and discuss songs made with Sequincer, and a Discord could be part of that. I'll announce it in the app if it happens. Meanwhile, version 2.0 is out with new editing gestures and an interactive tutorial. I'd love to hear what you think! There is a contact form in the settings page for any feature request.

Great release

Super app for its presentation, performance and flexible integration into all sorts of app workflows

Poor

32 beat limit on all files within the free version. I can understand why they did it, but the experience I had composing within those 32 beats was horrible. You cannot select and move notes, a system that is implemented in many other sequencers, because then you would be able to bypass the 32 beat system. Notes can erase other notes if you accidentally drag the duration a slight bit past it. And if you edit a note duration of for example Bb, if it is in front of other B notes you have placed in the same session, there is a chance that ALL NOTES YOU HAVE PLACED IN THE B ROW ARE ERASED. This is because for some reason it makes the duration of the first note you play in the column big enough to destroy all other notes.. the sequencer is fundamentally flawed. This bug would never happen in a million years on other sequencers. There are some sequencers that you can use in just a fire fox tab that are better than this. Would not recommend.

Response from developer

Update: thank you for this detailed review. You were right, and version 2.0 addresses most of it. • Moving notes: hold a note and drag it anywhere. With the Select tool you can select several notes and drag them together. • Notes erasing others: extending a note now stops at the next note on its row. A note in the way is only removed if you deliberately keep pushing into it. • B and B♭ in the same row: you can switch the grid to 12 notes, so every pitch has its own row. The bug that erased a row of notes when changing a duration is fixed. There's also a new interactive tutorial. I'm sorry the first experience was so frustrating. If you give it another try, I'd love to hear what you think.

Great Start for orchestrations

Takes a smidge work to get around. Great for importing music XML and editing. Best for seeing overall composition and sending midi parts.
