PDF Manual

The other day I received this in my mailbox:

I created a PDF Manual for Changeling from the web based manual you have online:


I like having offline manuals, and thought I’d share it with you to post online for other people to download if you want.


Thanks Jesse, that is so nice!

Dyads and User defined chords

Changeling Sequencer 1.4 is available in the App Store today!

It’s been a while since 1.3, and I blame the developers of Rocksmith for that ;-)

Seriously fun & addictive, but anyway:

This release of Changeling Sequencer brings two new types of chords you can select from the Chord dial.


The Dyad chord type adds the following voicings:

  • Root + Third
  • Root + Fifth
  • Root + Seventh
  • Rootless shell voicing: Third + Seventh

If you still feel that you are missing chord options the following feature might be for you!


The User chord type adds 5 voicing options that you may configure yourself!

You can do this in ‘edit mode’. Edit mode is activated by toggling the edit icon next to the keyboard lock. This icon is only visible when ‘user’ is selected as chord type.


After you enable edit mode, the keyboard scrolls to the middle root, and the scale degrees that are part of the user defined chord will be highlighted. You may toggle any scale degree on or off by touch (even the root note), as long as one scale degree remains part of the chord. It’s also possible to change the chord definition during playback of a recorded sequence, in order to find a chord that sounds right.

Have fun! And please send any support questions, feedback and/or feature requests to changelingsequencer@gmail.com


DJ/Producer Maxime Dangles created a Max4Live patch for Changeling Sequencer, and emailed it to me!

 I made that for fun and to improve my max/msp knowledge.

The patch allows you to control and record parameter changes from Ableton Live.

But I guess it’s also convenient for Live users with several control surfaces because with this you can configure a fixed CC MIDI mapping from Live to Changeling.

You can download the patch here.

Thanks Maxime!

In goes the MIDI

Changeling Sequencer 1.3 is available in the App Store now!

As some of you have requested after the first version was released, I have added a few ways of controlling Changeling Sequencer from an external midi controller.

In Diatonic mode:

The white keys on your physical keyboard correspond with the on-screen scale degrees; C = I, D = ii etc. The black keys are remapped to the serve the following functions:

  • Db: cycle scale down
  • Eb: cycle scale up
  • Gb: cycle root note down by the configured ‘modulation interval’ (default is semitone)
  • Ab: absolute root note change, the following key you press will be the root note
  • Bb: cycle root note up by the configured modulation interval

In Gated Input mode:

All midi notes that are not part of the current scale are discarded. This can be used for importing existing midi sequences into a pattern from an external midi sequencer/player.

When the Trigger screen is active in Changeling Sequencer:

Midi notes can be used to trigger patterns, the default mapping starts at midi note 48

Triggers are added to the queue unless the velocity is larger than 100, then they will change the pattern immediately.

You may use ‘midi learn’ to assign midi CC’s to the available parameters.


Forthinking, Vol. 2

This is awesome!
Jeff McLeod pointed me to a new recording of his:

I used Changeling on everything to control my synths (Voyager and Fizmo) and other apps (Molten Drum & Magellan). Every track on Vol. 2 features Changeling! Great fun, and it really allowed me to build all of these sounds.

Changeling sequencer 1.2 released!

In response to your feedback of the last version Changeling Sequencer is now playing a lot nicer with other apps. This includes MIDI clock sync.

In addition, version 1.2 contains two new big features: Trigger mode and Tracks mode.

Trigger mode

  • assign/unassign sequences to one of the 16 pads with a longpress gesture
  • trigger a sequence instantly by tapping an assigned pad
  • add a sequence to the queue by swiping upwards on the pad
  • remove a sequence from the queue by swiping to the left on the queue
  • toggle the queue loop

Tracks mode

  • switch instantly between tracks, by tapping the track number
  • mute and or solo tracks, toggle multiple tracks with one swipe!
  • change the assignment of midi channels by tapping on the selected track number
  • split chords of one track across different midi channels,
  • by assigning a root midi channel that is different from the main channel.
  • activity indicators for each track

To complement these two new features a ‘clone’ button was added to the sequence browser, so you can make variations of entire sequences fast and easy.


Jupiter Mozart Variations

Awesome to see Changeling Sequencer 1.1 in action on the first day!

This video was posted on YouTube by nakanosyun.

Thank you very much nakanosyun!

This is really interesting sequencer. I tried changing from Mozart’s famous phrase. You can also play external synthesizers via MIDI.


Changeling sequencer 1.1 is now available in the App Store!

Included are a lot of the features that have been requested in your reviews and emails:

  • Quantization
  • MIDI export by e-mail. The MIDI export recording is started by touching the play button in idle mode. Touch the stop button, and the export button will light up.
  • Multiple undo and redo, for a more robust saving experience
  • Custom soundfont (also for the people that think the default sound is not loud enough :-))

But the big bonus in this version is the new Tracks feature, and all the stuff that comes along with it. I’m pretty pleased with how this is turning out.

You now have 16 layers per sequence available, each one is tied to a MIDI channel (for now). Switch between tracks directly by using the tracks button, or cycle through them by swiping up and down the pattern area. You will see the active color change, also the channel number will update next to the sequence title.

Each track can be configured with its own set of parameters. New basic workflow: start out with recording melody line, transform it to a chord progression, switch to another track in playback mode, start improvising a solo until you hear something you like. Switch back to record mode (while continuing to loop). Hit some keys, undo and redo until you are satisfied.

By default all tracks share the same scale and root note. But you have the option to lock (and unlock) a root note and/or a scale for individual tracks. Try this by doing a longpress gesture on the ribbons, locked steps will be marked by a ‘*’.

This is a pretty cool feature, for it allows you to do a couple of things.

  • Improvise like a (basically) trained Jazz musician
  • Fix patterns to external channels that shouldn’t change midi notes, such as drum tracks.
  • Play out of tune, so use with moderation ;-) But it’s fun to find out what works together and what doesn’t.

Okay, I’m looking forward to hearing new feedback. Hopefully it’s as constructive as with the first version, so that I can continue to improve Changeling Sequencer with your help!

changeling sequencer in action

http://wwww.apps4idevices.com created this movie, thanks guys!

Changeling Sequencer allows you to record a simple melody (monophonic) and to change all recorded notes in various ways. (Scales, Root’s note, Transition & Arpegiator). This App is well done and you can use it as a MIDI controller too! A Super App!
