As @Eli claims i don’t post m u s i c, i propose this tune for beginners with a well-known tune Au clair de la lune in French, how you call it into your own country ?
I introduce an idea for futur : the use of json format to save parameters.
We can do with array yes we can.
# NLB - 25-03-2020
# Au clair de la lune -
# understand how to code a little tune
# use of json format for the hype (or not)
# use robert
require "json"
# json may be useful or not :-)
# See in the futur
# the idea : save into it parameters modified by knob of a midi device.
