Multiple Oled displays

Hi there,

I have been looking for ages but can't seem to find the answer. For my diy hauptwerk organ I want to use 70 to 80 0.95 inch OLED displays. Preferably SPI full color displays. Unfortunately I can only find information using one or two dispays. Does anybody know how to wire this and what librarys to use? A single arduino doesnt have enough ports to drive that many displays. How am I going to solve this?

Kind regards from the Netherlands,

Daan

What sort of update rate do you expect / require?

They only need to update when starting the organ or when loading a different organ, so just occasionally.
