Thanks for answering!
Who is the OP?
The Original Poster. :)

Me? Well, if it is me... yes, I would like to have NULL as init value.
But, I understand that [change] must work like it works right now.
It's OK.
I use "I go bananas" patch to make it work (with [+ 1]). Then, I read
Jonathan's reply... that has the same fix (with [* -1]).
Thanks everyone.

Subject: Re: [PD] [change] bug?
that's the way it works alright.
Yes. It's helpful to know that in Pure Data, an object that takes an
optional float argument
typically sets the value to zero if the user doesn't provide an
argument.
It's not a requirement: an external author can set the default value
to anything they want.
It's just that doing that requires extra work (i.e., manually
checking the arguments), whereas
defaulting to zero happens automatically.
Anyway, I think the OP might want [change] to default to NULL-- that
is, let the next incoming
value pass no matter what because there isn't a previous value yet.
That could be handy.
You can make your own version of that by first sending a copy of the
incoming value through a
spigot:
[spigot 1]
|
[* -1]
|
[set $1(
|
[change]
Then set the right inlet of [spigot] to zero and send the incoming
value to your [change]
object, and it will be guaranteed to pass.

If your first value sent to it is zero, just initialize it with some
other value as the argument

If i create [change] and send it a [0(, it outputs nothing. It
seems like it has already the 0 value initiated.
I think [change] should not work like this...
