An expressive, matrix-controlled arpeggiator designed to play with your thumbs. Control super fast arpeggios with precision, and apply pitchbend, tremolo, and vibrato with the iPad’s accelerometer. • "Arpeggionome makes amazing patterns in arrays of pulsing circles" (Peter Kirn, Create Digital Music) • "A masterpiece in design and functionality" (smitematter.com) • Rated as the "Most Creative MIDI App" by iPadMusic.com • "Arpeggionome Pro is a very very powerful arpeggiator that can really take your music to the next level" (Chip Boaz, iosmusicandyou.com) • "If you like great Arpeggiators, this is it!" (Jordan Rudess) Design an arpeggio pattern with various knobs and buttons, then move up-and-down the matrix to set its speed, or left-and-right to set its pitch. Tilt the device to control volume and pitchbend, or shake for vibrato. Arpeggionome Pro also features a robust MIDI implementation, allowing you to control other iOS music apps, external gear, and computer software like never before**. *An arpeggio is a musical technique where notes in a chord are played in sequence, rather than together. ** MIDI input and output is recommended for iPad 2 and later. Supports MIDI, Ableton Link, Audiobus 3, and Inter-App Audio. Please note, the App Preview video features Arpeggionome Pro controlling Animoog, an incredible synthesizer app created by Moog. Arpeggionome Pro does a have a built-in synthesizer, but... it doesn't sound as good that :] ## Key features - Matrix-controlled arpeggiator - Accelerometer for pitchbend, tremolo, vibrato - Adjust speed and pitch with matrix - Robust MIDI implementation - Ableton Link support - Audiobus 3 and Inter-App Audio support ## What do users think of Arpeggionome Pro | matrix arpeggiator?

There are so many ideas, ### 5/5 — Arpeggionome Pro *2026-01-03, version 1.3.0* January 3 2026 ### 1/5 — Awful *2023-10-09, version 1.3.0* If I could get a refund I would take it. Waste of sonic energy. ### 5/5 — Отличный арпеджиатор *2022-10-20, version 1.3.0* 5+ Отличная штука, активно пользуюсь. Респект создателю. Добавить бы еще побольше гамм ### 1/5 — Bad idea *2022-10-06, version 1.3.0* A interface não é intuitiva, tudo é muito confuso, os arpeggios são estranhos, está mais para um videogame do que para ago que possa colaborar com sua produção musical. Não dá pra fazer arpeggios como um Juno ou korg antigos. Não recomendo. ### 5/5 — Outstanding *2022-03-06, version 1.3.0* Clever, inspiring, useful. ### 4/5 — Excellent but doesn’t play well with others *2022-01-11, version 1.3.0* Would really like to use as an instrument in iMPC Pro 2. Or even work with Audiobus 3. But, it doesn’t. Other than that, it’s really really fun to play with! ### 3/5 — Crippled *2021-11-29, version 1.3.0* This app is perhaps fun to use and as such, a toy, it’s pretty well designed. Unfortunately, it is seriously crippled if you want to use it for more serious applications. The reason is the lack of ability to create your own scales. Any decent arpeggio generator allows at the minimum a creation of your own scale. This app is missing all 7th chord scales which are a must in any music, same goes for augmented and diminished scales. Yes, you can create some of those by using a chromatic scale and then finding a combination of notes distance but then you are limited only to that very specific note distance (I was able to create a diminished scale this way but that is only because of its symmetrical nature, very hard if not impossible to create 7th scale). In addition, surprisingly the app does NOT offer ability to create arpeggios on the fly based on the notes you press on a MIDI keyboard or the built in keyboard (which is there only to provide visual representation of the arpeggio) - this is something that almost every arpeggio generator has, both software and hardware. All you can control with the incoming MIDI is either changes of patterns or programs, NOT individual notes! I noticed that this developer does not like 7th chords / scales as they are also missing in the Fugue Machine preset scales, but since in Fugue Machine you can input your own notes using chromatic scale, this is not a big problem. Phrygian scale is included but nothing 7th scale (Phrygian scale can be achieved simply by starting on the 3rd degree of a major scale, no separate scale needed). All in all, this app has a great potential but is leaning on the side of being a gimmick, a toy and not a more serious music creation app. Another note, the video included in the Preview above on the App Store is misleading and suggests that the matrix can take multi touch (there are two points in performance matrix and two flashing cross hairs). This is not how the app works, in fact it states in the manual that “when the performance matrix receives multiple touches, only the last touch is active”. ### 4/5 — Needs new update *2021-07-20, version 1.3.0* I use this all the time. Sounds great with Bose Speakers. But it’s time for an update. Last 1 was 4 years ago. Maybe more colors. Please add all you avid users of this app. Let’s keep this going. ### 1/5 — Not intuitive *2021-02-23, version 1.3.0* To use it with garage band it's tricky and the registration on it it is elaborate to do. I do not feel I spent my money in the right way. If I could, I would ask for a refund.

NEW FEATURES ABLETON LINK SUPPORT! Ableton Link is a new technology that synchronizes beat, phase and tempo of Ableton Live and Link-enabled iOS apps over a wireless network. It's awesome. Go to Settings>Ableton Link Settings for more info. AUDIOBUS 3 MIDI SUPPORT Audiobus 3 brings MIDI support to Audiobus, and Arpeggionome Pro is good to go :] 64 LIL BITS Arpeggionome Pro now supports 64 bit architectures. Yee. DOTTED NOTES! Arpeggionome Pro has a new setting called 'Matrix Mode', which adds dotted note values to the Performance Matrix. To try it out, go to Settings >Interaction Settings and set Matrix Mode to 'Halves+Dotted+Triplets'. You'll notice the matrix now has two columns of squares, triangles, and dots. ■ Rows with squares play rates that are perfect halves of a measure — starting at 1/2 at the bottom row. ● Rows with dots play rates that are the dotted values — i.e 1.5x the length of the square row above. ▲ Rows with triangles play rates that are triplet values — i.e. 0.33x the length of 2 square rows below. ALT INTERACTION SETTINGS In Settings>Interaction Settings, you'll also find a new button at the bottom of the list called "ALT Interaction Settings". This is an alternative interaction state that I recommend trying. It's a bit more difficult to control, but I find the results quite interesting. Compared to the "Default Interaction Settings", it uses the new Matrix Mode setting and disables Retrigger for all parameters. BUG FIXES VIRTUAL MIDI CLOCK BUG In previous versions, when listening for MIDI Clock on the Arp MIDI In port, Arpeggionome Pro read the MIDI clock twice, and therefore went twice as fast as it should. Fixed now. NOTES ABOUT THIS UPDATE Hey, it's been a while! The last time I looked at the Arpeggionome Pro code base was over 2.5 years ago! Time is weird. In any case, I'm really glad to finally get this long overdue update of Arpeggionome Pro out. And I'm especially excited about adding Link and the new Matrix Mode setting. ON LINK By supporting Link, Arpeggionome Pro has actually become more playable, and perhaps in a not-so-obvious way. I'll explain… As you may know, Arpeggionome Pro is designed to play super fast arpeggios. Further, it's designed to be held in your hands in portrait mode, so you can quickly perform changes with your thumbs. Also, under the hood, all changes you make are quantized — allowing you to anticipate time by touching a parameter early, so the change happens at exactly the right time. This is great, and works very well… However! It's always been a challenge to start the sequencer from not playing to playing. You could press the play button and just let it run, but if you wanted to control starting and stopping in a more expressive way (which I very much prefer!), it gets a bit more complicated. That first touch would always happen the moment you touched, but every other touch would be quantized. Subtle difference for sure, but definitely weird. Ideally, what should happen is that all touches are quantized, even that first one. So that, when you stop and start playback, it starts quantized, just like the other touches. So, something exciting… This is exactly how it works now! And it's all thanks to Ableton Link :] ON MATRIX MODE… Basically, at some point after releasing Arpeggionome Pro, I realized how I missed an opportunity to have dotted note lengths on the Performance Matrix — it launched with just halves and triplets. Yes, I could have just updated the app… but since I try to be super strict about not changing UI after an application has been released, I just accepted it and moved on (see Fugue Machine and Link to MIDI). However… now that I'm here and revisiting the project, I figured out a way rationalize adding it… by simply burying it in an optional setting. I think I'm ok with this :] THANK YOU! Ok ok, that was many words. Thanks so much for your support and interest over the years (over 4 now!) and please reach out if anything comes up. ### 1.2.1 — 2014-09-08 Audiobus updated to support State Saving and Inter-App Audio. ### 1.2.0 — 2014-04-17 - Quick Start guide. - Performance enhancements.
