That sounds very good.
So you get stable readings with more than 10 bit resolution? (I don’t believe you 
please show some proof on a youtube video and tell how you did it)
The ADCs on the Teensys are actually even 16 bit… but since you can never get that stable because of the noisefloor they advertise it as “up to 13 bit” - which is probably under laboratory conditions.
If I could have 12 bit I would be completely happy, as this marks the threshold where it’s no longer possible to move a knob to an exact value. But for me, I got 10 bit at best, and it was more stable on an Arduino, which has only 10bit ADCs to begin with.
