I'm trying to do a pretty basic operation, and although I think it should be easy to do it just isnt working - anyway what i want to do is manipulate data by drawing directly onto arrays, to control envelopes for example. I'm using tabdump to create lists from the arrays and lister to store the lists however i can't seem to figure out how to get the lists to control anything, for example what's necessary to send the lists from lister to a line~ external? just hooking them up doesnt seem to work. Does the line~ external need more data than what i am giving it? or does the data from lister need to be "played" (i see from just hooking lister to a number object that the value remains static) I've spent ages looking for the answer myself and can't seem to find it so i'd be grateful for any help. thanks.

have you seen envgen from ggee? it's a graphical breakpoint envelope editor that outputs a list you can feed to line~.

thanks, i'll check that patch out, on the ggee front though i think i immediately investigated it when i heard of the envgen object (i have a peculiar obsession with drawn envelopes) but i think i found that it was linux only or that it contained no binaries or something (i have yet to find time to learn how to compile - it should be pretty simple but i think my computer has issues with compilers and havent sorted it out becuase i dont think it would be a good use of my time at the moment) but i think i'll look into it again just in case.

line~ only accepts 1 or 2 element lists at a time.
Further I hereby predict: You won't be happy with array drawing for more than one week or one month. Better use something else. Maybe look into data structures but they take more time to understand (I'm still struggling often...)

-how come? is the use of arrays in pd innately problematic? i know that large arrays seem a little cpu hungry (or at least they slow down the gui or something) but for now all i want is a very quick way to draw synth and filter envelopes, probably i will use more purely data based envelope controls in the future but there is something to be said for the visual simplicity* that drawing can achieve...
*in light of things simplicity probably isnt the right choice of word..;-)

Oh, nothing against drawing, drawing is great. But arrays as they currently are done in Pd feel so awkward and they hurt audio computation so much, that I don't think that anyone is using them over a long time.
Try 7.stuff/data-structures/5.array.pd for an alternative.
