Because I am not particularly smart, here are some of my notes.
"Vcc is your +9V power supply
Vref is a voltage reference, R2 and R3 from a voltage divider so that output is roughly at 4.5 volts. This is used in pedals where you have opamps and other components that need to be biased to a voltage above 0V so AC signal can pass through."
(From Seljer.)That's a thing I need to keep in mind.

I'm way too dumb to use opamps. I'm still too dumb to understand transistors.
Note Performer is a sample library specifically for music scoring apps. It can be used with Dorico. But what can also be used with Dorico is the Spitfire BBC library, which I already have.
