[PD] copy data between arrays

[Peter P.]

Hi list,

I am sure this has been asked many times, but I can't find a solution in
the mailing list archive. How can I copy data between arrays, in my case
arrays of 480000 samples without using externals and without blocking
the DSP computation (causing dropouts)?
I know that I can write to disk and read from it again, but is there a
way that does not require disk access?

Thanks for all ideas!
Peter
