I think it does! Upsampling vs downsampling.

I do realize that zipper noise might appear if the control rate of for 
instance a fast amplitude envelope is too low. That's why it would be 
more flexible to have adjustable contaolrate. This is one of the ways 
csound gets it's speed.

Nope, not needed...

hopefully LADSPA2 can address this.  Many new users have this problem, 
but it's basically unavoidable. :/


I still don't see why users should be kept from using controlrate.

> An audio rate signal is an entire buffer of values (say, 512, or 
whatever your jack buffer size is), but a control rate signal is just a 
single value for each block.  Once proper end user documentation exists, 
I'll try to explain this well..


I guessed all that (except that controlrate is locked to jack 
buffersize) from how things work in csound, no need (for me at least) 
for an explanation...
