Hi all, I'm a bit confused about the grain rate of [line] the help says that 'the default grain rate is 20 ms' however, when I connect a [delta] to a [line], it shows zero's, while inserting a [speedlim 20] changes that. also some other tests in attached patch. can someone explain ?
as matju already stated, [delta] is something, a lot of people (including me) do not know.
assuming it is the same as: | [t b b] | | [timer] |
then it "looks" like you get "0", whereas in reality you get: [20, 0( [*]
the "20" shows up so incredibly short (and is then overwritten by "0", that you simply cannot see it. [print] usually allows you to track such things, as you not only see the last value, but the entire history.
[*] why? when [line] receives a new target, it will immediately send out the start value, and then (in grain-time ms) the next value until it reaches the target value. in your case this translates to:
- you generate the first number ("7") and send [7 20( to [line]
- line will immediately output the current value ("0") and after 20ms it
will output the next value ("7")
- at the "same" time, you generate a new value ("9"), and send this to
[line], which will immediately output the current value ("7").
since both the start value and the target value are output at the same logical time, [timer] caluculates a time-difference of "0", which will be visible for the next 20ms.
the way I understood it, [delta] is the equivalent of: [image: delta.png] I also don't know where I got [delta] from, it doesn't seem to have a help patch associated with it. anyways, replacing [delta] with the above gives the same result. but I'm starting to see why... Tim
