So thanks to a lot of help, I have my Bela playing Soundfonts (on the sd) over Midi And Osc, I can issue program changes from either. I also knocked up a VST that forwards Midi over Osc so I can sequence as well as play 'Live'.
I'd like to put a web interface on Bela that can retrieve and soundfonts lists from my Bela program - I can do it on my laptop but I'd like to be able to control selection from my phone or an iPad without external apps.
I've had a hack around with OSC.js and various equivalents but am scratching my head....
I realise this is out of scope but I just wondered whether anyone had had a go at something similar ?
