External Memory for saving Pure Data array values

I am working on a Pure Data patch that I want to use with the Daisy Seed to create a guitar pedal. One problem I’m having is that the arrays created won’t be remembered after I turn off the pedal. Is there a way to utilize external memory so that the arrays will be there when the pedal is turned on?
I was kind of thinking of not using the SD card support because it only needs to remember 700-800 float values.

Wow thank you so much! <3
