Ok, you're right about the encs, much more easier for bank changing.
About the faders, i read that it's possible to plug 8 pots directly onto the core, wouldn't that be possible with faders ?
So to sum it up: Core, AINSER64, Din/Dout, and 1Din for encs + Led digit to indicate on which bank i am.
I was planning a 16 led/button matrix for starters, is the left space on the DIN usable to plug the bank selector encoder ?
And if I go for a 32 matrix, how do i plug the bank encoder ?
I haven't considered an LCD because i need to control a DAW, since all the features will be displayed on screen, is i worth it?… (also, money's short…)
Also, should i use tact switches or rubber button ? I don't really get how to make the connections between the buttons and the DIN.
Thanks !
