yep !
1. easiest it is done in message domain !
the zexy-external provides functions to convert signals to messages and
back again. (pack~ & unpack~)
this is kind of annoying, when there should be more delays
2. make a sub-patch with blocksize=1
=---------
|block~1 |
----------
unfortunately pd cannot reconstruct the signal from block~1 to block~64
so you have to do this manually : pE : via the pack~ & unpack~ objects
i attach a demo patch for both solutions
mfg.sfs.gtr
