Very much enjoyed the comments on octave/keyboard. I forget there are composers who like to modulate.
Both your comments are an enhancement. You also seem to know a lot about synths. Tell, me: how does one find how many (and over what time period) of a certain synth were made? Like - the Yam TG33 : nice unit, but I've never seen one other that the one we put in up at SUNY.
