I'm trying to make an abstraction that toggles between 1 and -1 at audio rate whenever its input decreases, so I came up with this:

I reduced the block size in the hope that it would reduce the delay of send~/receive~ to 32/44100 seconds, but I'm getting the following errors:

receive~ 1011_nextVal: vector size mismatch
sigsend 1011_nextVal: unexpected vector size

I was lead to believe this should work from the [block~] help file:

"Patches using send~/receive~ or throw~/catch~ to intercommunicate must have the same blocking -- and if their parents are blocked bigger than they are, there might be weirdness."

Am I doing something wrong?

I have to say....it's remarkable how often I find the answer to my question while composing it or within minutes of posting it. Apparently send~/receive~ doesn't work at block sizes other than 64, and one should use tabsend~/tabreceive~ instead. Not sure how I stumbled across this post from 8 years ago. I do think the [block~] help file is misleading though.
