I agree about the [trigger] object - from the demo patches the
significance didn't get through to me.
about the angriness, it is certainly my perception that tricked me -
communicating in the writing using just a few words skips the
niceness that we express with body language etc. this group is
incredible helpful - I just need to count my posts and constructive
replies received.

Who's angry? Arguing with strangers on the internet is about the
biggest waste of time I can imagine! ;-)In any case, [trigger] is the object you should investigate more,
as it makes the situation you want possible: change on both sides
of the [+] creates output.See attached.

Derek, I went through M-P's patches, trust me. He talks a lot about
looping etc but not about trivial stuff that I mentioned. I knew flossmanuals but the dat flow tut escaped my notice. there
is a very suitable example that is practical to me. Thank you very
much for pointing me there. For the sake of replying one rather angry reaction (I guess he
won't read) - when incrementing a coarse / fine value of for
instance tuning it is totally irrelevant which parameter is
changed first. the point is to output a new value whenever either
is changed. So pointing out that the hot/cold logic is essential
to pd's workings doesn't even remotely give me a clue. But that's ok, nobody is perfect. Thanks again for the patient posters, I appreciate a lot. Jurgen On Nov 21, 2008, at 7:50 PM, Derek Holzer wrote:Hi Jurgen,
understanding hot and cold is essential to understanding the way Pd handles order of operations, so it's best to learn it right from the start. In your example, it is unclear/ambiguous whether the fine
number gets sent to the add before or after the bang gets sent to the
coarse number. (This is determined by creation order, which cannot be
seen on the screen). This can lead to errors later.The preferred way is to use [t b f], where the [f] outlet is
connected to the cold side of the [+], and the [b] outlet is connected to
the hot side of the [+]. A bang to the hot side of many objects tells it
to do the same operation again with the information contained in the
inlets. In this case, the hot inlet will have the previous number stored
in it as well. All this is explained in Miller's HTML manual, the
"control" documentation patches, and also in the in-progress Pd FLOSS Manual: http://en.flossmanuals.net/puredatabest! Derek

Hi,
when using an [+] object I find it most of the time
counterproductive that the right inlet is considered cold.for example, if I want to use 2 different controls for 'coarse' and 'fine' tuning parameters it is necessary to add them together.
however when changing 'fine' value which for instance is connected to
the right inlet the new value is only taken into consideration once the
'coarse' value connected to the left inlet is changed as well.the only workaround I found was to [bang] the hot inlet form the
cold one as illustrated in the attached patch. but I don't find that
elegant.is there a better way to make both inlets hot?
