Reached #1 on the App Store in the Top Paid Music App Category.

The most advanced AUv3 MIDI note editor, modular sequencer and clip launcher on iOS.

Notes:
- This plugin does not run as a standalone app and requires a compatible host.
- MIDI is not sound. To make sound you'll have to feed the MIDI into a synthesizer or instrument app. Bring your own synths!
- Hardware integration with controllers requires iCloud Drive.

Compatibility:
- Special integration with hosts: AUM and Drambo.
- Tested hosts: ApeMatrix, Audiobus, BeatMaker, Cubasis, MTS, Zenbeats. Limited support by NanoStudio 2. Not supported by GarageBand.

Build live sets for clip launching, or an entire track with unlimited length. Play the whole sequence, or adjust the loop markers to iterate over a single section. Step input, or record as played, all with perfect timing accuracy.

Write your own code, share it with the community! You can control hardware devices, adding support for new controllers or completely changing the behavior of existing ones. Build your own styling with custom layouts and themes. Change colors, fonts, sizes… make it yours!

Piano Roll 2 takes all the features you love about the first installment, and expands them into an entirely new breed of modular sequencer and clip launcher, unparalleled in flexibility and depth on iOS. We redesigned it from the ground up to incorporate a plethora of new features and workflows.
- It's a sequencer that augments the capabilities of your host or DAW.
- It's a composition tool that helps you to write beautiful melodies and complex polyrhythmic patterns.
- It's a clip launcher that integrates seamlessly with supported hardware controllers.
- It's a scripting playground that lets you customize your workflow with code.
- It's a swiss-army knife of possibilities when working with MIDI.

Here are just some of the many use cases this modular architecture supports:
- Build live sets for clip launching.
- Compose patterns with touch, Apple Trackpad and Apple Pencil, or use the step input mode to write melodies step-by-step.
- Capture performances in real time and export your patterns as MIDI files.
- Import and edit MIDI files created in other apps, or from commercial packs.
- Record generated MIDI of other plugins or sequencers.
- Write harmonies and counterpoint melodies by superimposing the patterns of other Atoms as ghost lanes.
- Construct complex polyrhythms by taking advantage of custom time signatures and grid fractions.
- Sequence the sequencers for full modular mayhem.

What’s New

Version 2.0.10

- Infinite undo. Edit fearlessly.
- Improved channel targeting: long pressing a channel’s show/lock buttons will now toggle them exclusively, for easier channel switching.
- Improved interplay between user configurations and custom styles: now always using larger fonts when the selected configuration demands them. Configurations (such as Larger Controls and Sausage Fingers) support an "includedStyle" field which always applies the specified stylesheet. In effect, you can now use "Larger Controls" with "Larger Fonts" in combination with "MIDI Channel Colors".
- Added a "MIDI Note Data" example style that shows all note info, including the note’s octave, value, velocity etc.

Note: When iOS notifies Atom of system-wide memory pressure, very old undo/redo history will be discarded.

The most amazing timeline AU available.

Atom 2 is wonderful. It is leagues ahead of the competition and by that I do mean even most DAW midi editor pale in comparison.

There’s only one serious contender against ATOM 2, and that is Helium. Both are amazing apps, and at the moment I use each for its own strength.

What i’d like to see coming to ATOM 2? Midi CC curves. Maybe this is available already but I haven’t found a way to “SEE” my midi CC data. It can record it, but it doesn’t seem to display it anywhere.

Helium has a sort of curve editor which works wonderfully for automation, whether it is recorded or drawn the thing works perfectly. This is probably the one thing that ATOM 2 is missing.

Also, as a side question, is there such a thing as an “undo last recording”? That is one thing I have done issue with - ATOM 2 can Undo so many levels, but as far as I can tell this has to happen note by note - it would be great if we could maybe keep undo pressed to undo the whole last recording, sometimes I have to press undo like 30 times or simply rely on selecting it all and deleting it, but it would be better if an undo option for the whole last recording was available.

Anyway, ATOM 2 forever, and if CC editing doesn’t come around then I’ll just use Helium for CCs... but hopefully in the future I can have it all in ATOM :).

EDIT: Multi-channel support, automation, and MPE recording are all now available with the latest update.

Works as advertised, seems like exactly what I needed

I even rebooted the iPad after install, and AUM and AudioBus both agree that this doesn’t appear to be available. Not as an audio unit extension, and not as an inter-app audio device. I’m going to try to uninstall and reinstall it and see if that fixes the issue.

EDIT: I’m an idiot! It’s a MIDI controller, not an input source! Duh! Yeah this is fine, that was totally my bad. Great job!

TOP TIER

Long story short, no other piano roll on iOS comes close to this. My only suggestions are chord inversion options and to make the velocity function more accessible. Currently I don’t enjoy having to go through a couple menus to turn up/down the velocities of all the notes at once.
