This is K0r-Drag.
A draggable chord triggered X/Y pad with dials to control key, scale, and variant.
I simply took the Harp Pad code, tweaked it to trigger chords instead of individual notes with the option to change thru a limited set of key, scale and variant types.
I was trying to do a drag capable arpeggiator but I wasn’t nailing it- so I went simple. I’m easily impressed, and if you are too- you might like it. You might not like it.
Either way- it’s free, it works, and only occupies a few kb’s of your precious space.
Directions for usage:
1.) simply load the script within the Mozaic AUv3 plugin inside your iOS host app (like AUM).
2.) route its MIDI output to your chosen synthesizer.
3.) hit play on your host transport
4.) drag your finger across the X/Y canvas interface. **
**Moving horizontally shifts through quantized chord progressions and scale degrees, while moving vertically dynamically morphs the velocity, chord inversions, or harmonic complexity—allowing you to fluidly sweep through expressive chord changes with a single continuous gesture.
