Fastest vanilla way now is to get the range from the source as a list with [array get] and then write to the dest with [array set]. It's faster than you'd think. You can do some minor bounds checking, but the way Pd ranges work mostly takes care of that for you.

Hey list,

Recently my rechunk~ abstraction has ceased to work. I've recently re-installed and, it seems the maxlib/arraycopy object is not working the way it used to. I used to send it a list with
[sourceArray start end destinationArray(
values,
but now, when the source array is longer than the destination array, I get error messages that:
arraycopy: start point 1223199 out of range for destination chunk_2_13
Where chunk_2_13 is an array created to be the same length as the chunk I wish to extract.

Does anyone have a better way of copying chunks from one array into another? Is there a vanilla way?

Questions, questions,
Ed
