[PD-dev] DEFDACBLKSIZE and DEFSENDVS

[Giulio Moro]

well if you are looking for sizes multiples of DEFDACBLKSIZE it is already feasible.
My original question was also about why it is defined in multiple places and why DEFSENDVS is defined separately, yet setting them to two different values gives errors.

I've wanted variable dac block size as well, for embedding libpd in a plugin.. I'm guessing PD doesn't play well with jack when jack's block size is less than 64?

the joys of having not needing to support multiple operating systems?

also, the overhead with a blocksize of 8 is considerably higher than a
blocksize of 64, so when using *heavy* Pd-patches you might hit
performance problems sooner than later.

anyhow, i'm all for having a variable dac blocksize
$ pd -dacblocksize 8

ain't this is a deja vu [1]?
