So…
With Experimental Setup - MIDI basic, you don’t have access to change the scale in your instrument ( you have a Pico?)
You do have access thru STAGE, the ones that are labelled.
For other scales:
- in Workbench, select the “Edit Tool”
- double-click on “scale talker 1” (to edit its content)
(change just the name of the scale for the one you would like to use instead) - click ENTER every time you change something.
- ok at the end
- and don’t forget to save the setup, maybe with another name.
Hope this helps, have fun with other scales 
Any doubts just let me know
I’m around…
