What's New

Version 1.8.2


- Allow multiple simultaneous connections to/from Bluetooth MIDI devices.


- Prevent Pianoroll Draw Mode from creating notes outside the part.
- Fix rare crash when exporting MIDI file with events that occur before the first bar.
- Fix wrong display of number of active MIDI inputs in "Sources" panel when Audiobus was connected as a source.

Version 1.8:


- SIDEBAR: Audiobus sidebar for switching between connected apps, with access to all Xequence transport controls (Play, Stop (the Rewind icon) and Record) from any other Audiobus app.

- SYNCHRONIZATION: Full synchronization (Start, Stop, Tempo, Phase). Please note that Ableton Link has to be enabled in Xequence, all participating apps, and Audiobus.

- MIDI OUT: 16 Audiobus MIDI Out ports for connecting up to 16 Xequence instruments to 16 separate Audiobus MIDI lanes or apps. Displays connected apps' names inside Xequence.

- COMPATIBILITY NOTE: Some apps hosted in Audiobus as a MIDI receiver might not work correctly due to implementation issues in these apps. In these cases, please send the MIDI directly to the app (do not put the target app on Audiobus' MIDI screen. Instead, put it as a source on the Audio screen and select the app itself as the MIDI Destination on Xequence's instruments screen). This problem can only be fixed by the receiver app developers.

- MIDI IN: Audiobus MIDI In port for recording the MIDI output of other Audiobus apps. (all input will currently be merged to a single track, i.e. multitrack MIDI recording is not yet supported, but will be in a future update.)

- MIDI THRU: Xequence's usual MIDI Thru will also work inside Audiobus, passing whatever is received from the MIDI lane OR from any other source selected in Xequence's settings to the current track's instrument, which can be an Audiobus destination, hardware, OR another app.

- STATE SAVING AND RESTORE: Xequence will save the current project, including all modifications done since the last save, in the Audiobus preset, and restore it when a preset is recalled.

- MIDI MERGE: Xequence merges all MIDI input both from the Audiobus lane AND any other MIDI sources, both hardware and software, and can record it or send it to the current track's instrument (MIDI Thru).

- Please note that Audiobus MIDI and State Saving still are very new and evolving technologies, and you may encounter issues which are caused by problems in third-party apps. However, please do let us know if you have a problem that you suspect might be due to a Xequence bug, and we're happy to investigate!


- MIDI Input has been cleaned up: The "Any" source has been replaced by "Xequence Destination" and can be enabled alongside the other available sources. To send MIDI to "Xequence Destination", most apps have a menu that will list "Xequence Destination" so you can send to it. Of course, the other way around (Xequence actively connects to other sources) is still available by enabling one of the other sources in the "Select MIDI sources" panel.
- Better contrast for instrument colors in "Light" theme.
- Pianoroll: When switching between note and velocity editing, scroll and zoom are now preserved.
- Various optimizations.


- Pianoroll: Fix vertical scrolling of keys on the left sometimes not in sync with scroll position of editor.
- Pianoroll: Fix slightly wrong vertical zoom in Drum editor mode when using "Zoom All" with the ruler enabled and "Ruler Auto-Dismiss" disabled.
- Keyboard: Fix sliders with "Return" option sometimes not returning to their zero position.

At last!! A professional sequencer


At last!! A professional sequencer that supports the iPhone as well as the iPad!!!! This thing is awesome!!! It is a work of art!! Even with a small iPhone screen, it is easy to use. Everything is well laid out. Having worked with MIDI before, I didn’t even need to look in the manual!! Music beginners do note, however, this is a midi sequencer. It is a professional tool. You will also need a MIDI instrument in order to hear sound from it. I mention this, because I worry that newbies who don’t understand what they are buying will get frustrated or upset and give poor ratings because they don’t understand how midi sequencers work—this is the real thing—not a toy!! Very full featured!! This app is one of the best things to come along in a long time to the iOS music-making community. 5 Stars!!!

Awesome workstation


With midi import export implemented this is my favorite workstation. Stable, easy to use.

I do wish however we could grab midi files directly from drive or Dropbox, it’s been very frustrating trying to bounce midi files all the way to the device itself sometimes at the end of the process they are greyed out in the files ap so I can’t copy them to xequence folder. So please just let us import from Dropbox soon.

Developer Response

Thanks, we know that this was a highly sought-after feature and we tried to fit it in as soon as possible (the app was first released only three months ago!). So, glad to see everything's sorted for you now.



Buy this. This sequencer does what others don't. I paired this with Korg Gadget and now have everything I need to make iOS music.

Most other iOS DAW software has one fatal flaw: the sequencer. Enter Xequence. This works like a desktop DAW, and integrates with just about any software you can imagine, giving you the freedom to create music as you go, rather than trying to learn the quirks of your app.

Read the manual and learn how to turn your iPad into a music creation operating system. AUM and Audiobus combine to give you options that FINALLY allow you to use all your apps to full advantage.

Spend the bucks and buy the in app purchase of unlimited tracks.

Easy, sensible and powerful, worth every penny.
