this has a bunch of stuff it uses an older version of pd sometimes but you can work around it , they changed a couple object names.

this is how you convert the other one, I dont really use symbol lists yet. so I looked it up on the help page for pack object.
abcd_rollover.pd

here I made an odometer thing
mod4_rollover1.pd

aaaa aaab aaac aaad aaba aabb aabc aabd aaca aacb aacc aacd

the ones place goes through "a,b c d" over and over and then the tens place changes to b when you hit "a" again. and then when the ones place changes to a "a" third time the tens place changes to "c" etc etc.

if you have a four number set. you would end up with 4x4x4x4 lists right?
so it looks like 0-9999 except that 0-9 is actually a 4 number set instead of a 10 number set. so you count upward and use the numbers as symbols but you only use 4 before rolling over. that might work.

if you want to turn the knobs . its not very complicated probably. you can send it stuff with like two or three object boxes without doing very much work.

you can set it up as you work. you have to use message boxes with loadbangs. and have it save your array etc. each position where you need a saved number you need to get it prepared to save . it doesnt really have a full save system.

look at "make note" you connect makenote to noteout
. also, note out doesnt send to note in.
