finally got around to trying this out …
I think I understand the basics (perhaps not) but Im not getting sound out of timbre.
can someone just help me get that first step…

but Im not getting any sound out 
(Id watch some more youtube videos on orca, but YouTube appears to be having issues at the moment!)

so bangs has to be right, so simplest patch is

..'14C.0
