Is there anyway to store data separately inside abstractions not using arguments?
For example, say if there's an abstraction that writes a waveform to array from it's input, is there anyway to store the array values in abstractions separately when the parent patch was saved?

A possible solution would be to give each instance of the abstraction a unique identifier as an argument and have them save and load the data to disk using a filename based on this identifier. This solution does use arguments but it only uses one.

[table myTable 32]

[loadbang] <- auto load table data
|
[i $1] <-$1 is the unique id
|
[read tabData-$1.txt(
|
[s $0.myTable] 

[bang( <- save table data
|
[i $1]
|
[write tabData-$1.txt(
|
[s $0.myTable]

With an id of 4 this will load the contents of tabData-4.txt into the abstraction's own $0.myTab array. The [bang( will write the contents of the array back out to tabData-4.txt.

@portabello That's a very nice solution!

Thank you so much!
