Nice to be here.
I hope this isn't a bad question - I am totally new to synths and to reading patch notes for synths. I found these patch notes (they relate to the Arp 2600, for a track by Todd terje).
I am unsure about conventions on patch notes but on the image there are many areas where there is no settings, preset or annotation marked in.
My question would be what assumptions should I make for the areas of the plan which are unmarked? And more simply why would these have been left blank?
