Made some new Orba presets!

I was following along with what Andrea Mannocci said in a previous post and ended up making a few presets, one of which I like enough to share. It is a mod of the Cartridge Chords preset with more sustain / reverb and some filter movement. Tilt is kinda odd, not sure how to make this part better but hey, Its a start! File attached, place it with the other presets in the Artiphon folder within your directory. (search for .orbapreset and you will find the directory).

Thanks so much for all of your feedback. We’re happy to announce that we’ve now created a way for you to easily customize the sounds on Orba and create your own presets. You can check it out in our new thread here: 

I used images all the way up to 180kb and 800x800, no issues. The preset files were almost 200kb and still transferred perfectly on a mac using USB C.


There is now a *super cute* pixel art bread slice hugging a little pat of butter as the art, I could not be happier! Now I just need to find out which of the curves I set messes up tilt.

Any time now support team. Ready for some documentation help annnnny time...

FYI, the image I used was only 2kb but was 400x400 pixels before converting it and it reduced the file size of the preset by half. Still loads and plays fine. Seems that if the package size is an issue this is a big area to optimize.


BTW, default images are 120x120.

Ha! Fantastic! We may not be l33t hackers but we will make this little device bend to our whims! Off to go find digital butter pics...

Ah! That's an easy one! What you call "hash" is the base64 encoding of the image; if you copy the string and paste it here (, you'll get back your image. So if you want a custom image, you need to follow the inverse process (

I have not tried yet though... not sure what's coverImageHash

Sweet! Cant wait to try it. I am also interested in finding ways to add other pics to the presets using that large hash data at the top. Seems to be the bulk of the data they are sending actually. 

Ended up in a theremin like experiment (Lead)

Also, fundamental, in order to make any lead preset diatonic it suffices to change the last bit to

<TuningEntry key="C" name="Major" intervals="P1, M2, M3, P4, P5, M6, M7, P8"
               midiOctave="3" transpositionType="RetainNotes" type="tonal" tuning="60, 62, 64, 65, 67, 69, 71, 72"/>


BTW, if you end up messing things the bad way, you can always uninstall the application, delete the presets folder and reinstall. Everything will be recreated with default values.

Or you could use this zip file to restore factory presets.

I've been diffing some random bass presets: for modifiers and seekers (whatever they are) only the uuid is changing. Same for BezierCurvesEntry, GestureCurveAssignmentsEntry, EventCurveAssignmentsEntry; no change.

However, they do change across different kind of presets (e.g. Bass VS Chords)

It is only a time matter before nerdy hackers reunite under this thread! :D

Nope this should be quite doable. As far as the bezier curve, all the presets seem to use the same one so this does not seem to be a source of sound shaping as of yet. I even changed some of the bezierCurvesData hash and it did not break anything. Seems to be a placeholder and other than that I am at a loss as to how to alter the sound further. Seems to be the bulk of the shaping is done in the Synthpatch area. Orba team, any help you can add would be tops as we are trying to make the best of what we have here :)

I'd really love a synth lab area in the app where you can fiddle with patch params and send the preset live to orba to try. In fact, it wouldn't be that hard to implement, IMHO.

Also, while we wait (hopefully) for official documentation, if there's anyone is willing to contribute documenting parameters here, i.e. function, allowed range, etc., it would be more than welcome. @Sam, did you get to understand other parameters than the ones in the synth patch? Those are kind of straightforward, however others, e.g. gestures, bezier curve, etc., are quite cryptic to crack open.
