So Atom is an AUb3 Midi Step Sequencer
Because it's an AUv3 plugin you will be able to load as needed instances as your iDevice can support and your project needs.
Each instance equals a midi channel or a midi instrument.
One instance will use around 3% of CPU
Each instance can have a sequence (named loop) with a different Length, Time signature and Tempo speed (Tempo multiplier).
A Piano roll on the left side. (Scroll up and down with 2 fingers, pinch to Zoom in & out.
A Draw tool (1 Tap to add a note, one more to delete), an Eraser, a Divider, and a Multi selection tool. (Tap to select multiple notes or tap to add a note to the selection)
Notes length can be set from both directions.
This is cool as well as the ability to Zoom in the selected notes only.
Of course we have a Snap to Grid feature and a Grid setting menu.
2 arrows allow you to transpose one octave up or down the selection.
A Duplicate selection tool.
A Quantize menu.
A pop-up widow to set the Velocity of the selection..
A quite interesting Stretch function (video) and the possibility to Flip notes horizontally or vertically.
The ability to select a Scale from the 32 available. The selected scale will be displayed throughout the grid.
The possibility to display ghost's notes of another Atom instance.
And finally a multiple Undo and Redo.
Now, I will explain you why I choose to make the Atom | Piano Roll review today.
Yesterday I had to start a new casting for a Netflix movie (one more time I have to keep the silence about it and I think you can imagine how it's difficult to me)
So because of this I had to change my plan...
I had to choose a very very very easy review.
I choosed to make the Atom | Piano Roll review.
That may seem like a strange choice regarding all the features described above....
Don't you think?
I have a lot of Apps in my iPad that are wisely waiting for their turns. Apps that might seem much simpler, faster to review.
But, no, I have chosen Atom because this App is so understandable that we don't have to think while you are using it.
Everything makes sense for anyone who has already worked with a Midi Step Sequencer.
But don't get me wrong, it doesn't mean that Atom is not a professional tool but despite all its features it will only take you 5 minutes to get started...
This is the real Strength of this Midi Step Sequencer !
Atom is the AUv3 Midi Step Sequencer for iDevices.
The one you should recommend to your friends and hide to your enemy.
Atom is close to the perfection!
If I am saying close it's only because there is one thing and one thing only that I will be really happy to have in a future update.
This is the ability to add cc in the Velocity window.
Just in case I need it...
Atom | Piano Roll is my Midi Step Sequencer and I am sure that it's already the Midi Step Sequencer of all the lucky iOS musicians who own it.
Atom | Piano Roll is a Killer App, a Must have!

The App Store description
Piano Roll is a sequencer for iOS, and the first in our Atom series of modular sequencer plugins. Record, replay, loop and manipulate MIDI notes anywhere.
The MIDI audio unit can be loaded in compatible hosts (AUM, ApeMatrix, Audiobus, BeatMaker 3, Cubasis 2, etc.). Make sure your host is capable of loading, transmitting to, and receiving MIDI from audio unit MIDI plugins.
It’s intended to augment existing MIDI processing capabilities, or in scenarios where a host doesn’t provide sequencing functionality out of the box.
1) Loop record
Grow your ideas over any number of bars. Overdub drum loops, layer complex melodies, or even record an entire track. Arm recording in multiple instances, in the background, receiving from hardware or even other audio units. Piano Roll is always sample accurately synced with the host.
2) Step input
Quickly create sequences. Insert notes respecting grid length, and resize them to any duration. Layer chords in one operation. Just send the notes, Piano Roll takes care of the rest.
3) Extensive editing tools
All the standard editing tools you are used to are implemented, pen for entering notes at any length, brush for painting continual notes at grid size and scissors for slicing.
Advanced tools allow you to be productive. Grow notes backwards or forwards. Group notes with additive selection. Select rows or chords in one operation. Time and pitch flip. Velocity editing is precise and unobtrusive. With Piano Roll, anything you need is a tap, hold, or swipe away.
3) Non destructive quantize
Quantised or not? You decide when, and how much! Enable full quantisation beforehand with grid snapping. Turn it back off, or adjust the strength afterwards on an already recorded sequence. Choose the quantisation percentage for note starts, note ends and even note durations. In Piano Roll, you have full control over timing precision.
4) Dynamic stretching
Stretch a clip from 4 bars to 8. Fix the note lengths or extend them in harmony. In Piano Roll, your sequences are elastic.
5) Advanced time signatures
Does 4/4 sound boring to you? Create complex polyrhythms by choosing any timing. From 3/8 to 11/8. From 2/1 to 17/16. Piano Roll lets you invent your own rhythm.
6) Advanced tempo settings
Negative BPM? No problem. Pick a tempo for every clip and play backwards or forwards. Multiply host tempo or choose something arbitrary, all with extreme accuracy. Piano Roll gives you control over tempo like never before.
Never go outside a scale, or go chromatic and add spice to the melody. With scale overlays, your music isn’t forced to sound in a predetermined way, and you aren’t forced to be a music theory genius to sound the way you want. Piano Roll gives you the ability to decide in which key to be and when.
8) Visibility layers
Aid composition by overlaying other clips from other plugin instances over the one you’re editing. Make sure your chords are in harmony with the melody, visually. Piano Roll roll helps you focus where you need, when you need it.
10) State saving
Your sequences are saved alongside the project you already work with. And they’re loaded back automatically when opening up a project. Clips can be saved as host presets. Piano Roll is in perfect harmony with the host you already use.
