wrong HP, module is 21 not 19


i'm curious how others work with 1 v/o in - what is the use if the slightest touch on the pitch knob will change pitch? why would one want to to struggle so much to be in tune? can anyone help me out here, what am i missing? why can't c be a c, as a standard, and the diluting of pitch correctness be an extra? i guess it's both module specific and eurorack in general, but i find it so cumbersome to work with, i'm starting to wonder if i'm missing some super simple way of thinking about it that will make it all settle, or, naturally, if eurorack isn't for me.
