I think prophet is my new favorite synth :wink:

The piano distorts a bit, but I didn’t want to record it again.

Wow! Beautiful, esp the chord progression around 2’20"

Am wondering about ‘case’ - is it a different language or in another documentation source? I sometimes see techniques I’d like to understand and can’t find in Lang/tutorial. Thank you!

It’s the way Ruby does switch

I dont remember where I picked up the “case”, but I find it very useful. I dont know if there is a better way to do these selections. Since Sonic Pi is build on Ruby then we basically can check if something from the normal Ruby language works in Sonic Pi.

I think I watched this video as some point.
