I want to make (or someone else to make) following product:

a pcb that attaches behind any pocket operator
it solders to the 2 pots of the pocket operator. (left is pitch right is morph)
teensy is on pcb.
software (its already exists in current opensource shipping product) makes teensy act as a midi host
Incoming midi notes are being mapped onto pot shift value thats transmitted on the pot, in order to make pot value equal to the last input (via usb) start note
some cc is mapped on morph pot
midipitchbend is added to pot value

is it doable? how do i make a pcb? what do i even need besides connection of all pot contacts to analog in outs of teensy? is it direct connection?

know no physics software engineer. can route pcb if you draw schematics
