[PD] using tabwrite~ for a circular buffer?

[Johnny Mauser]

Funny incident as i was searching for this today as well.
I indeed used a delay line in combinatin with tabsend~ and a banged switch~
to be able to have an up to date table of 8192points every 40ms at a
samlingrate of 44.1k. Hope this gives any clues, esle i could give an
example tomorrow.

Best,

Johnny
