Thanks to the help from the answers I received from my previous post, I was able to go further into my first patch--which is a 6 oscillator drone machine.
After I added some waveform switching using [selector~] I can only get one oscillator (Osc 3) to make sound, even though the routing is the same for each oscillator.
I'm uploading the patch so someone can take a look. Sorry for the mess! (it's my first creation so if there's strange programming going on, any help would be appreciated)
