To me the behaviour of [phasor~] and [line~] seems just fine, they are both
time depended and simply listen to the internal clock. The problem rather lies
in the convertion from samples to milliseconds/frequency. You can't trust
[samplerate~] there because it doesn't reflect the implicit upsampling for the
overlap.
I think the easist solution is to add some documentation and warnings in the
[samplerate~] and/or [block~] help patches for the overlap case. This way you
don't have to worry about any back compatibility issues. After all, we've had
to live with for years and it's no problem at all once you are aware of it.
PS: I attached an even more confusing case, this time with [del]. [del 128 1
samp] won't make a 128 sample delay, because 'sample rate' is internally
defined the same way as in [samplerate~].
