[PD] pause writing to delay line / hybrid of array and delay

Hi Max, I'm responding to an email from another thread, but I think it
belongs here :)

So, I've seen your last revision of the patch and I'm not sure I get how it
is useful or why you need it like that. And now I'm really just curious and
interested in the applications of this.

It's nice that it is all vanilla, but it is still very limited as I see it.
You don't have sample accuracy for start writing and stopping or
pause/continue.

And I see that the looping (or ring buffering) isn't perfect either because
of this sample accuracy issue. You're analyzing to see if your signal
counter goes over the array size but the resulting bang comes out after
some samples, so... clicks.

Anyway, this approach of yours is quite similar to what I did here with
objects from cyclone, have you checked it? Doesn't it do the same thing?
Does it fail for your needs somehow?

I just made an update to the ELSE library (version beta 37) and now I can
do the same with objects from ELSE, so I'm attaching it here.

Note I've also added a new [del~] object with a freeze option and also
included that functionality in [ffdelay~], but I guess that's something not
really appropriate for what you want, what do you say?

cheers
