[PD] Research delay

[Gintaras Lau.]

Hello João Pais,

exactly I'm looking for help to get on a track to understand the
situation for such approach in the world of sound technologies. I
noticed programmers use these tricks in they patches to get some
predictable or in-range randomization. I'm not quit sure about
formulation of question, because I was using commercial sound
sequencing software, VST's and etc. The opportunities of pd strongly
impressed me so I fought to use it in research I'm writing.

It's simple to use values of env~ and apply to control limiters,
delays and etc. What I expect to figure out is technological aspects
and theoretical approach. That's besides programming a patch, but I
couldn't hold my self to try. I saw people discussing various topics
(off programming) on list and did it my way. Nobody understood me on
pd~forum as well, so now I'm sure a revision and clarification is
necessary for the direction of my work


Thank you very much.
G
