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.}

2.0.10
May 29, 2021
- 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.
2.0.9
May 15, 2021
*** 16 channels in one instance ***
- New: Added support for multi-channel workflows. Each instance can sequence 16 channels (or “tracks” in non-MPE modes) which can be routed to any number of instruments.
- New: Each channel can be individually enabled, shown/hidden, or locked/unlocked (ghosted). Multiple channels can be shown and edited at the same time! Hidden or locked (ghosted) MIDI channels don't participate in new selections, processing operations such as quantize etc.
- Improved: The default multi-channel mode ("MPE") will now enable all channels by default. The newly added “Filter" mode works like MPE, but allows manual enabling/disabling of individual channels. The improved "Funnel" mode will funnel/copy all MIDI events into the selected channels and is useful for “faking MPE” with certain instruments.
- Improved: All channel focus/lock operations will now automatically update note entry settings. Manually inputting notes will respect the targeted channel, shown in the top-left. All note entry settings can still be customized by long pressing the “Add” button.
- Improved: The Magic Clipboard will now paste on the first "targeted" channel, shown in the top left. Long pressing the paste buttons will paste preserving the original channels, for more advanced use-cases.
Tips:
- You can use the "MIDI Channel Colors" theme when working with multiple channels in a single instance.
- Make sure your keyboard or MIDI source emits on the right channel. Atom 2 records everything exactly as received.
*** More automation and multi-take recording features ***
- Exposed an 'Add Empty Pattern' parameter to complement the existing 'Duplicate Pattern' and 'Clear Pattern' parameters for external control. Map them to a Note, CC or PC message using your host’s MIDI learn features. Now you can create a new take in your recording as a persistent pattern with just a single MIDI message.
- Added a more spontaneous way of arming recording on supported controllers: the global arm record button ("Capture MIDI") on the Launchpad X and Pro Mk3 will now arm/disarm the focused (visible) clips, no matter which mode the controller is in (e.g. arm the visible clip while in Note or Chord mode). The top-right logo on Launchpad controllers now will also illuminate with the color of the most recently focused (visible) clip.
- Added an easier way of controlling automation endpoints: with a simple “snapback automation” setting, enabled by default and available in the advanced launch settings, automation snaps back to its home value at each loop start. This makes recording automation such as a filter sweeps or crescendo modulations a lot easier. The home value is always set to the earliest value in the sequence.
*** Other new features and tweaks ***
- New: A new way of switching between note entry and note selections: on the Apple Pencil 2, double tapping will switch between the two input modes.
- New: Added an in-app toggle for switching dark mode on/off.
- New: Added an in-app toggle for disabling animations.
- New: Improved or changed various icons across the UI.
- New: When “loop” is off, clips will now automatically un-launch when reaching the end marker.
- Fixed: CC and aftertouch events are now properly funneled in thru mode when MPE is disabled.
- Fixed: Performance improvements when working with very long clips.
- Scripting: All MIDI callbacks in the scripting sandbox will now include the port info as the last argument.
- Scripting: Exposed `addEmptyActivePattern`, `armScene`, `getAllFocusedClips`, `hasFocusedClips`, `getAllRecordingTracks`, `hasRecordingTracks` methods to the scripting sandbox.
