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.
best!

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.

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:

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?
