all pd control data are computed between audio block, it's not just midi message.

no, all of them. but you may have many in 0 logical time.
see atttachement :
the metro output value every micro second.
timer can attest that all value are send.
but if you have a look at the recorded wav file, you'll see that value are changed every 1.6ms on my computer : i.e : blocksize (64) / audio frequency (48 000)
in fact, values are changed 1600 times between every audio block, and stable for a block.
