Hi Xavier
I don’t know if you remember but I met you a couple years back in Horsham - Tubular Bells etc.
Anyway I think what you are proposing would be great for Code Clubs if you could ‘render’ the Code from Trinket etc.
One of the problems with the Sonic Pi projects in Code Club is that it can’t be run in the browser like most the other projects can - event the Sense Hat now has an emulator.
If the kids could use Trinket and then ‘export to WAV’ etc I think you could be onto a winner.
