Pin 11 is the timing capacitor for the as3340. Some people are using high precision (5%) mylar capacitors for this, but on Sam’s BOM it is a simple disc capacitor. I have also used a disc cap, because at the time I did not even know that mylar exists 
. It works, my tuning is a bit off when I go to higher octaves, but I don’t know if I can blame the capacitor here, it’s probably the octave switch and I need to re-tune using this guide by antoine.
