Hey zyxy398!
Those ADC pins are for inputs as they are analog-to-digital converters.
Daisy comes with 2 DACs that can be used for CV outs.
I did talk about how we could possibly add more DACs in this post that I think you may find useful!! No Dac output with custom seed targets - #7 by Takumi_Ogata
Which programming language are you thinking about using by the way?
